• PASS: SQLRally Thoughts

  - by Bill Graziano

  The PASS Board recently decided that we wouldn’t put another US-based SQLRally on the calendar until we had a chance to review the program. I wanted to provide some of my thinking around this. Keep in mind that this is the opinion of one Board member. The Board committed to complete two SQLRally events to determine if an event modeled between SQL Saturday and the Summit was viable. We’ve completed the two events and now it’s time to step back and review the program. This is my seventh year on the PASS Board. Over that time people have asked me why PASS does certain things. Many, many times my answer has been “Because that’s the way we did it last year”. And I am tired of giving that answer. We need to take a step back and review the US-based SQLRally before we schedule another one. It would be irresponsible for me as a Board member to commit resources to this without validating that what we’re doing makes sense for the organization and our members. I have no doubt that this was a great event for the attendees. We just need to validate it’s the best use of our resources. Please keep in mind that we haven’t cancelled the event. We’ve just said we need to review it before scheduling another one. My opinion is that some fairly serious changes are needed to the model before we consider it again – IF we do it again. I’ve come to that conclusion after speaking with the Dallas organizers, our HQ team, our Marketing team, other Board members (including one of the Orlando organizers), attendees in Orlando and Dallas and visiting other similar events. I should point out that their views aren’t unanimous on nearly any part of this event -- which is one of the reasons I want to take some time and think about this before continuing. I think it’s helpful to look at the original goals of what we were trying to accomplish. Andy Warren wrote these up in August of 2010. My summary of these goals and some thoughts on each one is below. Many of these thoughts revolve around the growth of SQL Saturdays. In the two years since that document was written these events have grown significantly. The largest SQL Saturdays are now over 500 people which mean they are nearly the same size as our recent SQLRally. Our goals included: Geographic diversity. We wanted an event in an area of the country that was away from any given Summit location. I think that’s still a valid goal. But we also have SQL Saturdays all over the country. What does SQLRally bring to this that SQLSaturday doesn’t? Speaker growth. One of the stated goals was to build a “farm club” for speakers. This gives us a way for speakers to work up to speaking at Summit by speaking in front of larger crowds. What does SQLRally bring to this that the larger SQL Saturdays aren’t providing? Pre-Conference speakers is one obvious answer here. Lower price. On a per-day basis, SQLRally is roughly 1/4th the price of the Summit. We wanted a way for people to experience something Summit-like at a lower price point. The challenge is that we are very budget constrained at that lower price point. International Event Model.  (I need to write more about this but I’m out of time.  I’ll cover it in the next installment.) There are a number of things I really like about SQLRally. I love the smaller conferences. They give me a chance to meet more people than at something the size of Summit. I like the two day format. That gives you two evenings to be at social events with people. Seeing someone a second day is a great way to build a bond with that person. That’s more difficult to do at a SQL Saturday. We also need to talk about the financial aspects of the event. Last year generated a small $17,000 profit on revenues of $200,000. Percentage-wise that’s reasonable but on an absolute basis it’s not a huge amount in our budget. We think this year will lose between $30,000 and $50,000 and take roughly 1,000 hours of HQ time. We don’t have detailed financials back yet but that’s our best guess at this point. Part of that was driven by using a convention center instead of a hotel. Until we get detailed financials back we won’t have the full picture around the financial impact. This event also takes time and mindshare from our Marketing team. This may sound like a small thing but please don’t underestimate it. Our original vision for this was something that would take very little time from our Marketing team and just a few mentions in the Connector. It turned out to need more than that. And all those mentions and emails take up space we could use to talk about other events and other programs. Last I wanted to talk about some of the things I’m thinking about. I don’t think it’s as simple as saying if we just fix “X” it all gets better. Is this that much better of an event than SQL Saturdays? What if we gave a few SQL Saturdays some extra resources? When SQL Saturdays were around 250 people that wasn’t as viable. With some of those events over 500 we need to reconsider this. We need to get back to a hotel venue. That will help with cost and networking. Is this the best use of the 1,000 HQ hours that we invested in the event? Is our price-point correct? I’m leaning toward raising our price closer to Summit on a per-day basis. I think this will let us put on a higher quality event and alleviate much of the budget pressure. Should growing speakers be a focus? Having top-line pre-conference speakers helps market the event. It will also have an impact on pricing and overall profit. We should also ask if it actually does grow speakers. How many of these people will eventually register for Summit? Attend chapters? Is SQLRally a driver into PASS or is it something that chapters, etc. drive people to? Should we have one paid day and one free instead of two paid days? This is a very interesting model that is used by SQLBits in the UK. This gives you the two day aspect as well as offering options for paid and free attendees. I’m very intrigued by this. Should we focus on a topic? Buried in the minutes is a discussion of whether PASS should have a Business Analytics conference separate from Summit. This is an interesting question to consider. Would making SQLRally be focused on a particular topic make it more attractive? Would that even be a SQLRally? Can PASS effectively manage the two events? (FYI - Probably not.) Would it help differentiate it from Summit and SQL Saturday? These are all questions that I think should be asked and answered before we do this event again. And we can’t do that if we don’t take time to have the discussion. I wanted to get this published before I take off for a few days of vacation. When I get back I’d like to write more about why the international events are different and talk about where we go from here.

• How exactly are Distributed File Systems used in cloud environment?

  - by vaab

  How exactly are Distributed File Systems used in cloud environment ? More precisely: Are live VMs images (or their filesystem) usually located in the DFS ? Are VMs usually used to run the backbone (actual code) of DFS structure ? Precise example citing DFS (ceph, Gluster, GFS, GPFS, Lustre) or cloud environment (Openstack , CloudStack, ...) would be appreciated, even if I'm more interessted by ceph on OpenStack for now.

• The Changing Face of PASS

  - by Bill Graziano

  I’m starting my sixth year on the PASS Board.  I served two years as the Program Director, two years as the Vice-President of Marketing and I’m starting my second year as the Executive Vice-President of Finance.  There’s a pretty good chance that if PASS has done something you don’t like or is doing something you don’t like, that I’m involved in one way or another. Andy Leonard asked in a comment on his blog if the Board had ever reversed itself based on community input.  He asserted that it hadn’t.  I disagree.  I’m not going to try and list all the changes we make inside portfolios based on feedback from and meetings with the community.  I’m going to focus on major governance issues since I was elected to the Board. Management Company The first big change was our management company.  Our old management company had a standard approach to running a non-profit.  It worked well when PASS was launched.  Having a ready-made structure and process to run the organization enabled the organization to grow quickly.  As time went on we were limited in some of the things we wanted to do.  The more involved you were with PASS, the more you saw these limitations.  Key volunteers were regularly providing feedback that they wanted certain changes that were difficult for us to accomplish.  The Board at that time wanted changes that were difficult or impossible to accomplish under that structure. This was not a simple change.  Imagine a $2.5 million dollar company letting all its employees go on a Friday and starting with a new staff on Monday.  We also had a very narrow window to accomplish that so that we wouldn’t affect the Summit – our only source of revenue.  We spent the year after the change rebuilding processes and putting on the Summit in Denver.  That’s a concrete example of a huge change that PASS made to better serve its members.  And it was a change that many in the community were telling us we needed to make. Financials We heard regularly from our members that they wanted our financials posted.  Today on our web site you can find audited financials going back to 2004.  We publish our budget at the start of each year.  If you ask a question about the financials on the PASS site I do my best to answer it.  I’m also trying to do a better job answering financial questions posted in other locations.  (And yes, I know I owe a few of you some blog posts.) That’s another concrete example of a change that our members asked for that the Board agreed was a good decision. Minutes When I started on the Board the meeting minutes were very limited.  The minutes from a two day Board meeting might fit on one page.  I think we did the bare minimum we were legally required to do.  Today Board meeting minutes run from 5 to 12 pages and go into incredible detail on what we talk about.  There are certain topics that are NDA but where possible we try to list the topic we discussed but that the actual discussion was under NDA.  We also publish the agenda of Board meetings ahead of time. This is another specific example where input from the community influenced the decision.  It was certainly easier to have limited minutes but I think the extra effort helps our members understand what’s going on. Board Q&A At the 2009 Summit the Board held its first public Q&A with our members.  We’d always been available individually to answer questions.  There’s a benefit to getting us all in one room and asking the really hard questions to watch us squirm.  We learn what questions we don’t have good answers for.  We get to see how many people in the crowd look interested in the various questions and answers. I don’t recall the genesis of how this came about.  I’m fairly certain there was some community pressure though. Board Votes Until last November, the Board only reported the vote totals and not how individual Board members voted.  That was one of the topics at a great lunch I had with Tim Mitchell and Kendal van Dyke at the Summit.  That was also the topic of the first question asked at the Board Q&A by Kendal.  Kendal expressed his opposition to to anonymous votes clearly and passionately and without trying to paint anyone into a corner.  Less than 24 hours later the PASS Board voted to make individual votes public unless the topic was under NDA.  That’s another area where the Board decided to change based on feedback from our members. Summit Location While this isn’t actually a governance issue it is one of the more public decisions we make that has taken some public criticism.  There is a significant portion of our members that want the Summit near them.  There is a significant portion of our members that like the Summit in Seattle.  There is a significant portion of our members that think it should move around the country.  I was one that felt strongly that there were significant, tangible benefits to our attendees to being in Seattle every year.  I’m also one that has been swayed by some very compelling arguments that we need to have at least one outside Seattle and then revisit the decision.  I can’t tell you how the Board will vote but I know the opinion of our members weighs heavily on the decision. Elections And that brings us to the grand-daddy of all governance issues.  My thesis for this blog post is that the PASS Board has implemented policy changes in response to member feedback.  It isn’t to defend or criticize our election process.  It’s just to say that is has been under going continuous change since I’ve been on the Board.  I ran for the Board in the fall of 2005.  I don’t know much about what happened before then.  I was actively volunteering for PASS for four years prior to that as a chapter leader and on the program committee.  I don’t recall any complaints about elections but that doesn’t mean they didn’t occur.  The questions from the Nominating Committee (NomCom) were trivial and the selection process rudimentary (For example, “Tell us about your accomplishments”).  I don’t even remember who I ran against or how many other people ran.  I ran for the VP of Marketing in the fall of 2007.  I don’t recall any significant changes the Board made in the election process for that election.  I think a lot of the changes in 2007 came from us asking the management company to work on the election process.  I was expecting a similar set of puff ball questions from my previous election.  Boy, was I in for a shock.  The NomCom had found a much better set of questions and really made the interview portion difficult.  The questions were much more behavioral in nature.  I’d already written about my vision for PASS and my goals.  They wanted to know how I handled adversity, how I handled criticism, how I handled conflict, how I handled troublesome volunteers, how I motivated people and how I responded to motivation. And many, many other things. They grilled me for over an hour.  I’ve done a fair bit of technical sales in my time.  I feel I speak well under pressure addressing pointed questions.  This interview intentionally put me under pressure.  In addition to wanting to know about my interpersonal skills, my work experience, my volunteer experience and my supervisory experience they wanted to see how I’d do under pressure.  They wanted to see who would respond under pressure and who wouldn’t.  It was a bit of a shock. That was the first big change I remember in the election process.  I know there were other improvements around the process but none of them stick in my mind quite like the unexpected hour-long grilling. The next big change I remember was after the 2009 elections.  Andy Warren was unhappy with the election process and wanted to make some changes.  He worked with Hannes at HQ and they came up with a better set of processes.  I think Andy moved PASS in the right direction.  Nonetheless, after the 2010 election even more people were very publicly clamoring for changes to our election process.  In August of 2010 we had a choice to make.  There were numerous bloggers criticizing the Board and our upcoming election.  The easy change would be to announce that we were changing the process in a way that would satisfy our critics.  I believe that a knee-jerk response to criticism is seldom correct. Instead the Board spent August and September and October and November listening to the community.  I visited two SQLSaturdays and asked questions of everyone I could.  I attended chapter meetings and asked questions of as many people as they’d let me.  At Summit I made it a point to introduce myself to strangers and ask them about the election.  At every breakfast I’d sit down at a table full of strangers and ask about the election.  I’m happy to say that I left most tables arguing about the election.  Most days I managed to get 2 or 3 breakfasts in. I spent less time talking to people that had already written about the election.  They were already expressing their opinion.  I wanted to talk to people that hadn’t spoken up.  I wanted to know what the silent majority thought.  The Board all attended the Q&A session where our members expressed their concerns about a variety of issues including the election. The PASS Board also chose to create the Election Review Committee.  We wanted people from the community that had been involved with PASS to look at our election process with fresh eyes while listening to what the community had to say and give us some advice on how we could improve the process.  I’m a part of this as is Andy Warren.  None of the other members are on the Board.  I’ve sat in numerous calls and interviews with this group and attended an open meeting at the Summit.  We asked anyone that wanted to discuss the election to come speak with us.  The ERC held an open meeting at the Summit and invited anyone to attend.  There are forums on the ERC web site where we’ve invited people to participate.  The ERC has reached to key people involved in recent elections.  The years that I haven’t mentioned also saw minor improvements in the election process.  Off the top of my head I don’t recall what exact changes were made each year.  Specifically since the 2010 election we’ve gone out of our way to seek input from the community about the process.  I’m not sure what more we could have done to invite feedback from the community. I think to say that we haven’t “fixed” the election process isn’t a fair criticism at this time.  We haven’t rushed any changes through the process.  If you don’t see any changes in our election process in July or August then I think it’s fair to criticize us for ignoring the community or ask for an explanation for what we’ve done. In Summary Andy’s main point was that the PASS Board hasn’t changed in response to our members wishes.  I think I’ve shown that time and time again the PASS Board has changed in response to what our members want.  There are only two outstanding issues: Summit location and elections.  The 2013 Summit location hasn’t been decided yet.  Our work on the elections is also in progress.  And at every step in the election review we’ve gone out of our way to listen to the community and incorporate their feedback on the process. I also hope I’m not encouraging everyone that wants some change in the organization to organize a “blog rush” against the Board.  We take public suggestions very seriously but we also take the time to evaluate those suggestions and learn what the rest of our members think and make a measured decision.

• Windows Azure Evolution &ndash; Caching (Preview)

  - by Shaun

  Caching is a popular topic when we are building a high performance and high scalable system not only on top of the cloud platform but the on-premise environment as well. On March 2011 the Windows Azure AppFabric Caching had been production launched. It provides an in-memory, distributed caching service over the cloud. And now, in this June 2012 update, the cache team announce a grand new caching solution on Windows Azure, which is called Windows Azure Caching (Preview). And the original Windows Azure AppFabric Caching was renamed to Windows Azure Shared Caching.   What’s Caching (Preview) If you had been using the Shared Caching you should know that it is constructed by a bunch of cache servers. And when you want to use you should firstly create a cache account from the developer portal and specify the size you want to use, which means how much memory you can use to store your data that wanted to be cached. Then you can add, get and remove them through your code through the cache URL. The Shared Caching is a multi-tenancy system which host all cached items across all users. So you don’t know which server your data was located. This caching mode works well and can take most of the cases. But it has some problems. The first one is the performance. Since the Shared Caching is a multi-tenancy system, which means all cache operations should go through the Shared Caching gateway and then routed to the server which have the data your are looking for. Even though there are some caches in the Shared Caching system it also takes time from your cloud services to the cache service. Secondary, the Shared Caching service works as a block box to the developer. The only thing we know is my cache endpoint, and that’s all. Someone may satisfied since they don’t want to care about anything underlying. But if you need to know more and want more control that’s impossible in the Shared Caching. The last problem would be the price and cost-efficiency. You pay the bill based on how much cache you requested per month. But when we host a web role or worker role, it seldom consumes all of the memory and CPU in the virtual machine (service instance). If using Shared Caching we have to pay for the cache service while waste of some of our memory and CPU locally. Since the issues above Microsoft offered a new caching mode over to us, which is the Caching (Preview). Instead of having a separated cache service, the Caching (Preview) leverage the memory and CPU in our cloud services (web role and worker role) as the cache clusters. Hence the Caching (Preview) runs on the virtual machines which hosted or near our cloud applications. Without any gateway and routing, since it located in the same data center and same racks, it provides really high performance than the Shared Caching. The Caching (Preview) works side-by-side to our application, initialized and worked as a Windows Service running in the virtual machines invoked by the startup tasks from our roles, we could get more information and control to them. And since the Caching (Preview) utilizes the memory and CPU from our existing cloud services, so it’s free. What we need to pay is the original computing price. And the resource on each machines could be used more efficiently.   Enable Caching (Preview) It’s very simple to enable the Caching (Preview) in a cloud service. Let’s create a new windows azure cloud project from Visual Studio and added an ASP.NET Web Role. Then open the role setting and select the Caching page. This is where we enable and configure the Caching (Preview) on a role. To enable the Caching (Preview) just open the “Enable Caching (Preview Release)” check box. And then we need to specify which mode of the caching clusters we want to use. There are two kinds of caching mode, co-located and dedicate. The co-located mode means we use the memory in the instances we run our cloud services (web role or worker role). By using this mode we must specify how many percentage of the memory will be used as the cache. The default value is 30%. So make sure it will not affect the role business execution. The dedicate mode will use all memory in the virtual machine as the cache. In fact it will reserve some for operation system, azure hosting etc.. But it will try to use as much as the available memory to be the cache. As you can see, the Caching (Preview) was defined based on roles, which means all instances of this role will apply the same setting and play as a whole cache pool, and you can consume it by specifying the name of the role, which I will demonstrate later. And in a windows azure project we can have more than one role have the Caching (Preview) enabled. Then we will have more caches. For example, let’s say I have a web role and worker role. The web role I specified 30% co-located caching and the worker role I specified dedicated caching. If I have 3 instances of my web role and 2 instances of my worker role, then I will have two caches. As the figure above, cache 1 was contributed by three web role instances while cache 2 was contributed by 2 worker role instances. Then we can add items into cache 1 and retrieve it from web role code and worker role code. But the items stored in cache 1 cannot be retrieved from cache 2 since they are isolated. Back to our Visual Studio we specify 30% of co-located cache and use the local storage emulator to store the cache cluster runtime status. Then at the bottom we can specify the named caches. Now we just use the default one. Now we had enabled the Caching (Preview) in our web role settings. Next, let’s have a look on how to consume our cache.   Consume Caching (Preview) The Caching (Preview) can only be consumed by the roles in the same cloud services. As I mentioned earlier, a cache contributed by web role can be connected from a worker role if they are in the same cloud service. But you cannot consume a Caching (Preview) from other cloud services. This is different from the Shared Caching. The Shared Caching is opened to all services if it has the connection URL and authentication token. To consume the Caching (Preview) we need to add some references into our project as well as some configuration in the Web.config. NuGet makes our life easy. Right click on our web role project and select “Manage NuGet packages”, and then search the package named “WindowsAzure.Caching”. In the package list install the “Windows Azure Caching Preview”. It will download all necessary references from the NuGet repository and update our Web.config as well. Open the Web.config of our web role and find the “dataCacheClients” node. Under this node we can specify the cache clients we are going to use. For each cache client it will use the role name to identity and find the cache. Since we only have this web role with the Caching (Preview) enabled so I pasted the current role name in the configuration. Then, in the default page I will add some code to show how to use the cache. I will have a textbox on the page where user can input his or her name, then press a button to generate the email address for him/her. And in backend code I will check if this name had been added in cache. If yes I will return the email back immediately. Otherwise, I will sleep the tread for 2 seconds to simulate the latency, then add it into cache and return back to the page. 1: protected void btnGenerate_Click(object sender, EventArgs e) 2: { 3: // check if name is specified 4: var name = txtName.Text; 5: if (string.IsNullOrWhiteSpace(name)) 6: { 7: lblResult.Text = "Error. Please specify name."; 8: return; 9: } 10:  11: bool cached; 12: var sw = new Stopwatch(); 13: sw.Start(); 14:  15: // create the cache factory and cache 16: var factory = new DataCacheFactory(); 17: var cache = factory.GetDefaultCache(); 18:  19: // check if the name specified is in cache 20: var email = cache.Get(name) as string; 21: if (email != null) 22: { 23: cached = true; 24: sw.Stop(); 25: } 26: else 27: { 28: cached = false; 29: // simulate the letancy 30: Thread.Sleep(2000); 31: email = string.Format("{0}@igt.com", name); 32: // add to cache 33: cache.Add(name, email); 34: } 35:  36: sw.Stop(); 37: lblResult.Text = string.Format( 38: "Cached = {0}. Duration: {1}s. {2} => {3}", 39: cached, sw.Elapsed.TotalSeconds.ToString("0.00"), name, email); 40: } The Caching (Preview) can be used on the local emulator so we just F5. The first time I entered my name it will take about 2 seconds to get the email back to me since it was not in the cache. But if we re-enter my name it will be back at once from the cache. Since the Caching (Preview) is distributed across all instances of the role, so we can scaling-out it by scaling-out our web role. Just use 2 instances and tweak some code to show the current instance ID in the page, and have another try. Then we can see the cache can be retrieved even though it was added by another instance.   Consume Caching (Preview) Across Roles As I mentioned, the Caching (Preview) can be consumed by all other roles within the same cloud service. For example, let’s add another web role in our cloud solution and add the same code in its default page. In the Web.config we add the cache client to one enabled in the last role, by specifying its role name here. Then we start the solution locally and go to web role 1, specify the name and let it generate the email to us. Since there’s no cache for this name so it will take about 2 seconds but will save the email into cache. And then we go to web role 2 and specify the same name. Then you can see it retrieve the email saved by the web role 1 and returned back very quickly. Finally then we can upload our application to Windows Azure and test again. Make sure you had changed the cache cluster status storage account to the real azure account.   More Awesome Features As a in-memory distributed caching solution, the Caching (Preview) has some fancy features I would like to highlight here. The first one is the high availability support. This is the first time I have heard that a distributed cache support high availability. In the distributed cache world if a cache cluster was failed, the data it stored will be lost. This behavior was introduced by Memcached and is followed by almost all distributed cache productions. But Caching (Preview) provides high availability, which means you can specify if the named cache will be backup automatically. If yes then the data belongs to this named cache will be replicated on another role instance of this role. Then if one of the instance was failed the data can be retrieved from its backup instance. To enable the backup just open the Caching page in Visual Studio. In the named cache you want to enable backup, change the Backup Copies value from 0 to 1. The value of Backup Copies only for 0 and 1. “0” means no backup and no high availability while “1” means enabled high availability with backup the data into another instance. But by using the high availability feature there are something we need to make sure. Firstly the high availability does NOT means the data in cache will never be lost for any kind of failure. For example, if we have a role with cache enabled that has 10 instances, and 9 of them was failed, then most of the cached data will be lost since the primary and backup instance may failed together. But normally is will not be happened since MS guarantees that it will use the instance in the different fault domain for backup cache. Another one is that, enabling the backup means you store two copies of your data. For example if you think 100MB memory is OK for cache, but you need at least 200MB if you enabled backup. Besides the high availability, the Caching (Preview) support more features introduced in Windows Server AppFabric Caching than the Windows Azure Shared Caching. It supports local cache with notification. It also support absolute and slide window expiration types as well. And the Caching (Preview) also support the Memcached protocol as well. This means if you have an application based on Memcached, you can use Caching (Preview) without any code changes. What you need to do is to change the configuration of how you connect to the cache. Similar as the Windows Azure Shared Caching, MS also offers the out-of-box ASP.NET session provider and output cache provide on top of the Caching (Preview).   Summary Caching is very important component when we building a cloud-based application. In the June 2012 update MS provides a new cache solution named Caching (Preview). Different from the existing Windows Azure Shared Caching, Caching (Preview) runs the cache cluster within the role instances we have deployed to the cloud. It gives more control, more performance and more cost-effect. So now we have two caching solutions in Windows Azure, the Shared Caching and Caching (Preview). If you need a central cache service which can be used by many cloud services and web sites, then you have to use the Shared Caching. But if you only need a fast, near distributed cache, then you’d better use Caching (Preview).   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

• Azure WNS to Win8 - Push Notifications for Metro Apps

  - by JoshReuben

  Background The Windows Azure Toolkit for Windows 8 allows you to build a Windows Azure Cloud Service that can send Push Notifications to registered Metro apps via Windows Notification Service (WNS). Some configuration is required - you need to: Register the Metro app for Windows Live Application Management Provide Package SID & Client Secret to WNS Modify the Azure Cloud App cscfg file and the Metro app package.appxmanifest file to contain matching Metro package name, SID and client secret. The Mechanism: These notifications take the form of XAML Tile, Toast, Raw or Badge UI notifications. The core engine is provided via the WNS nuget recipe, which exposes an API for constructing payloads and posting notifications to WNS. An application receives push notifications by requesting a notification channel from WNS, which returns a channel URI that the application then registers with a cloud service. In the cloud service, A WnsAccessTokenProvider authenticates with WNS by providing its credentials, the package SID and secret key, and receives in return an access token that the provider caches and can reuse for multiple notification requests. The cloud service constructs a notification request by filling out a template class that contains the information that will be sent with the notification, including text and image references. Using the channel URI of a registered client, the cloud service can then send a notification whenever it has an update for the user. The package contains the NotificationSendUtils class for submitting notifications. The Windows Azure Toolkit for Windows 8 (WAT) provides the PNWorker sample pair of solutions - The Azure server side contains a WebRole & a WorkerRole. The WebRole allows submission of new push notifications into an Azure Queue which the WorkerRole extracts and processes.

After installing this package, a WnsRecipe assembly is added to project references. To send notifications using WNS, first register the application at the Windows Push Notifications & Live Connect portal to obtain Package Security Identifier (SID) and a secret key that your cloud service uses to authenticate with WNS. An application receives push notifications by requesting a notification channel from WNS, which returns a channel URI that the application then registers with a cloud service. In the cloud service, the WnsAccessTokenProvider authenticates with WNS by providing its credentials, the package SID and secret key, and receives in return an access token that the provider caches and can reuse for multiple notification requests. The cloud service constructs a notification request by filling out a template class that contains the information that will be sent with the notification, including text and image references.Using the channel URI of a registered client, the cloud service can then send a notification whenever it has an update for the user. var provider = new WnsAccessTokenProvider(clientId, clientSecret); var notification = new ToastNotification(provider) {     ToastType = ToastType.ToastText02,     Text = new List<string> { "blah"} }; notification.Send(channelUri); the WNS Recipe is instrumented to write trace information via a trace listener – configuratively or programmatically from Application_Start(): WnsDiagnostics.Enable(); WnsDiagnostics.TraceSource.Listeners.Add(new DiagnosticMonitorTraceListener()); WnsDiagnostics.TraceSource.Switch.Level = SourceLevels.Verbose; The WAT PNWorker Sample The Azure server side contains a WebRole & a WorkerRole. The WebRole allows submission of new push notifications into an Azure Queue which the WorkerRole extracts and processes. Overview of Push Notification Worker Sample The toolkit includes a sample application based on the same solution structure as the one created by theWindows 8 Cloud Application Services project template. The sample demonstrates how to off-load the job of sending Windows Push Notifications using a Windows Azure worker role. You can find the source code in theSamples\PNWorker folder. This folder contains a full version of the sample application showing how to use Windows Push Notifications using ASP.NET Membership as the authentication mechanism. The sample contains two different solution files: WATWindows.Azure.sln: This solution must be opened with Visual Studio 2010 and contains the projects related to the Windows Azure web and worker roles. WATWindows.Client.sln: This solution must be opened with Visual Studio 11 and contains the Windows Metro style application project. Only Visual Studio 2010 supports Windows Azure cloud projects so you currently need to use this edition to launch the server application. This will change in a future release of the Windows Azure tools when support for Visual Studio 11 is enabled. Important: Setting up the PNWorker Sample Before running the PNWorker sample, you need to register the application and configure it: 1. Register the app: To register your application, go to the Windows Live Application Management site for Metro style apps at https://manage.dev.live.com/build and sign in with your Windows Live ID. In the Windows Push Notifications & Live Connect page, enter the following information. Package Display Name PNWorker.Sample Publisher CN=127.0.0.1, O=TESTING ONLY, OU=Windows Azure DevFabric 2. 3. Once you register the application, make a note of the values shown in the portal for Client Secret,Package Name and Package SID. 4. Configure the app - double-click the SetupSample.cmd file located inside the Samples\PNWorker folder to launch a tool that will guide you through the process of configuring the sample. setup runs a PowerShell script that requires running with administration privileges to allow the scripts to execute in your machine. When prompted, enter the Client Secret, Package Name, and Package Security Identifier you obtained previously and wait until the tool finishes configuring your sample. Running the PNWorker Sample To run this sample, you must run both the client and the server application projects. 1. Open Visual Studio 2010 as an administrator. Open the WATWindows.Azure.sln solution. Set the start-up project of the solution as the cloud project. Run the app in the dev fabric to test. 2. Open Visual Studio 11 and open the WATWindows.Client.sln solution. Run the Metro client application. In the client application, click Reopen channel and send to server. à the application opens the channel and registers it with the cloud application, & the Output area shows the channel URI. 3. Refresh the WebRole's Push Notifications page to see the UI list the newly registered client. 4. Send notifications to the client application by clicking the Send Notification button. Setup 3 command files + 1 powershell script: SetupSample.cmd –> SetupWPNS.vbs –> SetupWPNS.cmd –> SetupWPNS.UpdateWPNSCredentialsInServiceConfiguration.ps1 appears to set PackageName – from manifest Client Id package security id (SID) – from registration Client Secret – from registration The following configs are modified: WATWindows\ServiceConfiguration.Cloud.cscfg WATWindows\ServiceConfiguration.Local.cscfg WATWindows.Client\package.appxmanifest WatWindows.Notifications A class library – it references the following WNS DLL: C:\WorkDev\CountdownValue\AzureToolkits\WATWindows8\Samples\PNWorker\packages\WnsRecipe.0.0.3.0\lib\net40\WnsRecipe.dll NotificationJobRequest A DataContract for triggering notifications:     using System.Runtime.Serialization; using Microsoft.Windows.Samples.Notifications;     [DataContract]     [KnownType(typeof(WnsAccessTokenProvider))] public class NotificationJobRequest     {               [DataMember] public bool ProcessAsync { get; set; }          [DataMember] public string Payload { get; set; }         [DataMember] public string ChannelUrl { get; set; }         [DataMember] public NotificationType NotificationType { get; set; }         [DataMember] public IAccessTokenProvider AccessTokenProvider { get; set; }         [DataMember] public NotificationSendOptions NotificationSendOptions{ get; set; }     } Investigated these types: WnsAccessTokenProvider – a DataContract that contains the client Id and client secret NotificationType – an enum that can be: Tile, Toast, badge, Raw IAccessTokenProvider – get or reset the access token NotificationSendOptions – SecondsTTL, NotificationPriority (enum), isCache, isRequestForStatus, Tag   There is also a NotificationJobSerializer class which basically wraps a DataContractSerializer serialization / deserialization of NotificationJobRequest The WNSNotificationJobProcessor class This class wraps the NotificationSendUtils API – it periodically extracts any NotificationJobRequest objects from a CloudQueue and submits them to WNS. The ProcessJobMessageRequest method – this is the punchline: it will deserialize a CloudQueueMessage into a NotificationJobRequest & send pass its contents to NotificationUtils to SendAsynchronously / SendSynchronously, (and then dequeue the message).     public override void ProcessJobMessageRequest(CloudQueueMessage notificationJobMessageRequest)         { Trace.WriteLine("Processing a new Notification Job Request", "Information"); NotificationJobRequest pushNotificationJob =                 NotificationJobSerializer.Deserialize(notificationJobMessageRequest.AsString); if (pushNotificationJob != null)             { if (pushNotificationJob.ProcessAsync)                 { Trace.WriteLine("Sending the notification asynchronously", "Information"); NotificationSendUtils.SendAsynchronously( new Uri(pushNotificationJob.ChannelUrl),                         pushNotificationJob.AccessTokenProvider,                         pushNotificationJob.Payload,                         result => this.ProcessSendResult(pushNotificationJob, result),                         result => this.ProcessSendResultError(pushNotificationJob, result),                         pushNotificationJob.NotificationType,                         pushNotificationJob.NotificationSendOptions);                 } else                 { Trace.WriteLine("Sending the notification synchronously", "Information"); NotificationSendResult result = NotificationSendUtils.Send( new Uri(pushNotificationJob.ChannelUrl),                         pushNotificationJob.AccessTokenProvider,                         pushNotificationJob.Payload,                         pushNotificationJob.NotificationType,                         pushNotificationJob.NotificationSendOptions); this.ProcessSendResult(pushNotificationJob, result);                 }             } else             { Trace.WriteLine("Could not deserialize the notification job", "Error");             } this.queue.DeleteMessage(notificationJobMessageRequest);         } Investigation of NotificationSendUtils class - This is the engine – it exposes Send and a SendAsyncronously overloads that take the following params from the NotificationJobRequest: Channel Uri AccessTokenProvider Payload NotificationType NotificationSendOptions WebRole WebRole is a large MVC project – it references WatWindows.Notifications as well as the following WNS DLL: \AzureToolkits\WATWindows8\Samples\PNWorker\packages\WnsRecipe.0.0.3.0\lib\net40\NotificationsExtensions.dll Controllers\PushNotificationController.cs Notification related namespaces:     using Notifications;     using NotificationsExtensions;     using NotificationsExtensions.BadgeContent;     using NotificationsExtensions.RawContent;     using NotificationsExtensions.TileContent;     using NotificationsExtensions.ToastContent;     using Windows.Samples.Notifications; TokenProvider – initialized from the Azure RoleEnvironment:   IAccessTokenProvider tokenProvider = new WnsAccessTokenProvider(         RoleEnvironment.GetConfigurationSettingValue("WNSPackageSID"),         RoleEnvironment.GetConfigurationSettingValue("WNSClientSecret")); SendNotification method – calls QueuePushMessage method to create and serialize a NotificationJobRequest and enqueue it in a CloudQueue [HttpPost]         public ActionResult SendNotification(             [ModelBinder(typeof(NotificationTemplateModelBinder))] INotificationContent notification,             string channelUrl,             NotificationPriority priority = NotificationPriority.Normal)         {             var payload = notification.GetContent();             var options = new NotificationSendOptions()             {                 Priority = priority             };             var notificationType =                 notification is IBadgeNotificationContent ?

With WNS, tier integration is so automated that you don’t even have to leverage a HTTP push API such as SignalR. This is a pretty powerful development paradigm, and has changed the way I look at Windows 8 for RAD business apps. When I originally looked at Win8 and the WinRT API, my first opinion on Win8 dev was as follows – GOOD:WinRT, WRL, C++/CX, WinJS, XAML (& ease of Direct3D integration); BAD: low projected market penetration,.NET lobotomized (Only 8% of .NET 4.5 classes can be used in Win8 non-desktop apps - http://bit.ly/HRuJr7); UGLY:Metro pascal tiles! Perhaps my 80s teenage years gave me a punk reactionary sense of revulsion towards the Partridge Family 70s style that Metro UX seems to have appropriated: On second thought though, it simplifies UI dev to a single paradigm (although UX guys will need to change career) – you will not find an easier app dev environment. Speculation: If LightSwitch is going to support HTML5 client app generation, then its a safe guess to say that vnext will support Win8 Metro XAML - a much easier port from Silverlight XAML. Given the VS2012 LightSwitch integration as a thumbs up from the powers that be at MS, and given that Win8 C#/XAML Metro apps tend towards a streamlined 'golden straight-jacket' cookie cutter app dev style with an Azure back-end supporting Win8 push notifications... --> its easy to extrapolate than LightSwitch vnext could well be the Win8 Metro XAML to Azure RAD tool of choice! The hook is already there - :) Why else have the space next to the HTML Client box? This high level of application development abstraction will facilitate rapid app cookie-cutter architecture-infrastructure frameworks for wrapping any app. This will allow me to avoid too much XAML code-monkeying around & focus on my area of interest: Technical Computing.

• Where can I find more documentation on bulding an Ubuntu-based cloud infrastructure?

  - by Shazzner

  I've been reading: https://help.ubuntu.com/community/UbuntuCloudInfrastructure It's fascinating stuff, but documentation seems a bit sparse. Where I work, we have this aging, clunky VMWare ESXi setup for all our internal servers. I'd really like to read up on possible migration or just information on Orchestra, integration with Juju, etc that isn't a bunch of loosely connected blog posts. :p This is concerning 11.10 and, presumably, 12.04. To make this less vague, specifically documentation on: Orchestra - features, comparisons, videos, etc Integrating Juju with Orchestra - I'm familiar with using Juju for deploying on AWS, but that wiki page glances over connecting it to orchestra Building a private cloud - Advantages, using/deploying Openstack, etc Working with internal networks - Configuring DMZs, setting rules, etc Any recommended books would be appreciated too. I didn't intend for this to be a 'do all my homework for me! LMGTFY' post, I'm just hungry for information and haven't found a good repository of knowledge for much of this.

  Le Cloud marquera-t-il le retour des DRM ? Les labels militent pour imposer de nouvelles technologies de marquage très discrètes Les vendeurs de musique en ligne commercialisent de fichiers sans DRM. Cependant, il y a deux catégories chez ces commerçants : ceux comme Apple, Walmart ou LaLa qui distribuent des MP watermarkés (enregistrant les informations personnelles de leur propriétaire, ce qui pose problème si les fichiers sont partagés sur des réseaux P2P) ; et ceux comme Amazon ou Napster qui ont su résister aux pressions des maisons de disque et qui délivrent des MP3 propres.
