  • Cloud Providers that support FreeBSD?

    - by Jed Daniels
    I'm looking for recommendations from the wise and all-knowing Server Fault community on cloud hosting providers that support running FreeBSD. Ideally ones that don't require special tweaks to the FreeBSD system, but any recommendations would be appreciated. Suggestions? Recommendations? Advice? Tips? War stories? Thanks in advance.

  • Amazon EC2 migration from one region to the other

    - by Gnanam
    I'm using the following Amazon EC2 resources in the US East (Virginia) region: 1 Running Instance 1 Elastic IP 2 EBS Volumes 100 EBS Snapshots 1 Key Pair 2 Security Groups 5 My Own AMIs (customized based on my application stack) My instance is based on Linux distribution (CentOS) and my AMIs are S3-backed. Both EBS volumes are mounted on this running instance. We're planning to migrate our deployment to US-West region. Because Amazon EC2 resources are not shared across regions, my questions are: What are all the factors that I need to consider in advance? What are all the recommended & different ways of migrating each EC2 resources from one region to the other? Are there any hidden risks involved during and/or after the migration? Experts ideas/suggestions/recommendations on this are highly appreciated.

  • Reduce power consumption of gaming computer while idle

    - by White Phoenix
    This is my current build: EVGA X58 (first generation) motherboard Intel i7 965 clocked @ 3.3 Ghz 3x DDR3-1600 Corsair RAM at stock timings and voltages Corsair AX750 80 Plus Gold PSU 1 Optical Drive 1 Seagate 7200.10 500 GB drive 2x Western Digital Caviar Black 1 TB drives OCZ Vertex 1 60 GB EVGA GTX 460 oc'd at 800/1600/1850 Antec 1200 case HT-Omega Striker 7.1 Sound Card Windows 7 32-bit Professional (PAE Enabled) I've already seen this post Reduce power use on computer and this post How do I lower power consumption of my computer and while useful, I'm looking for answers specific to my build and OS. I'm pretty sure this build is a energy-intensive build by default, but I want to try to reduce the amount of energy my build uses when I leave it idle (when I go to bed or go out, etc). The first requirement for this machine is that I need to leave it on, so I cannot turn it off while it's being unused. I run it as a file server for personal reasons and I also leave it on in case people leave me messages on various IM services and chat clients (IRC, MSN, Steam, XFire, Pidgin, etc). I'm also unable to replace the parts in my computer with a cheaper "greener" part. What are some ways to minimize the amount of power the machine uses? I'm already using a high efficiency power supply (80 Plus Gold), but I imagine there's other things that can be done in the BIOS and Windows' power settings to reduce power usage while I'm not using the computer. From what I can tell, I can't use Sleep since that'll disable network access (whole reason why I leave the computer on in the first place). I already turn off my monitor when it's not in use. I enabled Intel SpeedStep within the BIOS (I know, I have a 965 and why am I enabling SpeedStep?) Should I bring the graphics card back to stock speeds and lower the clock on the processor even more? Main reason why I'm asking is I think this computer alone is the reason why my power bill is high, so I want to reduce its consumption to as low as possible without having to shut the thing down.

  • I need a few minutes of dedicated server a week, but not for hosting, just to convert ogg etc.

    - by talkingnews
    I'm completely happy with my webhosting, it's just that I need to do one little thing they won't allow, and that's run an instance of Sox to convert about 30 mp3s to ogg files, in various directories, a couple of times a week, to be done automatically in response to the detection of the upload of an mp3. Probably looking at a minute of server time over the whole week. I've had unhelpful suggestions on other forums like "why not leave your home PC on 24 hours a day and then use all your isp bandwidth to do this", which doesn't work for me. I know that I can host files on, say, Amazon S3, but is there something similar for my needs? All it would need to do would be: wget/ftp the mp3 files, convert them to ogg, ftp the files back to my hosting. Of course, all this wouldn't be needed if there was such a thing as a compiled binary of Sox (or any mp3ogg converter) for Centos which I could upload without needing root access, but I've given up asking that one, but always open to suggestions!

  • How to choose size for a cloud server (rackspace)

    - by Emil
    We're going to test the rackspace cloud next week to see how it's working with our web app. It's a LAMP environment with a lot of MySQL databases. How do I choose the "right" server size? On Rackspace I can choose slices with the memory of 256, 512, 1024, 2048, 4096 etc. Right now we don't have a lot of traffic (approx. 1000 visitors/day) but I thought the whole "cloud" idea was to not be limited and auto scale. Update: What I'm looking for is now a specification of what I need. I know it's too complex. I'm looking for examples, case studies etc. It would be interesting to hear something like "Yes we're serving 10 000 daily requests without spikes on a LAMP stack with only one slice on with 2 GB RAM".

  • which server is best for me??

    - by mathew
    I am looking for a best hosting service for my website. My website is a PHP MySQl driven site which hase got site scrapping for more than 10 websites and near about 8-10 API pursing and some about 150 mb dat file reading(from local hard drive), and also one rss pursing,Live graph from other sites, geo map from Google,Map api from Google and so on. one widget which real-time result for any one who chose the same. so my question is which is best option for me. actually I am considering softlayer cloud as they are pretty cheap and more facilities than rackspace. another option is a dedicated server which has 2 single core processor, 4GB ram and 250GB sata II. with 100 mbps uplink. so please tell me which will be the best option?? I heard that dedicated server has lots of limitations than cloud. but for cloud they uses SAN for storage so I am afraid the reading proces for database may be bit slower...and their basic plan ram is only 1 GB.

  • Monitoring System for the cloud?

    - by Maxim Veksler
    I need a monitoring system, much like ganglia / nagios that is build for the cloud. I need it to support : Adding / removing nodes dynamically. (Node shuts down, dose not imply node failure...) Dynamic node based categorization, meaning node can identify them self as being part of group X (ganglia gets this almost right, but lacks the dynamic part...) Does not require multicast support (generally not allowed in cloud based setups) Plugins for recent cool stuff such as Hadoop, Cassandra, Mongo would be cool. More features include: External API, web interface and co. I've looked at Ganglia, munin and they both seem be almost there (but not exactly). I would also go for reasonably priced Software as Service solution. I'm currently doing research, so Suggestions are highly appreciated. Thank you, Maxim

  • I need a relatively cheap host, which will be able to handle sudden peaks in traffic?

    - by Morten K
    Hello, We're launching a product in a few months, which will obviously have a website. Judging from our current traffic, we believe that overall traffic will probably not be that much, but we are aiming at promoting the site heavily using social media. This has the typical problem, that IF we get suddenly get picked up by a large tech blog, we will see a sudden burst: A very heavy increase in traffic all of the sudden. If we use a cheap charlie host as our current host is (www.unoeuro.com) or something similar like GoDaddy, I'm afraid that the site will go down under the load. If that happens, then we might as well have thrown our social media marketing dollars out of the window. Our site will be relatively lightweight, all videos hosted at Youtube or Vimeo and other than that mainly just a standard webpage (ie nothing too heavy). I am hoping for recommendations for a good hosting company, which has some form of scalable hosting, so if / when a traffic surge hits, the site will not go down.

  • Using WebSphere CloudBurst with PowerVM to AIX virtualization over a cloud

    - by ADD Geek
    hi there we are studying the virtualization option to reduce our datacenter cost, and this research was assigned to me. we looked into alternatives and we almost reached a conclusion that PowerVM is the only option to virtualize pSeries servers. we found no signs of cloud support explicitly mentioned in any document, however there was the mention of CloudBurst. from the videos we watched and the documents we read, it seems that CloudBurst is more oriented towards Application Servers (WebSphere Software). but our environment is not relying only on WebSphere. we have some banking applications, Oracle Databases and MQ/Broaker. the question is: 1- can we virtualize the existing applications (all running AIX) on a cloud running on top of some of the existing servers? (given that we do the sizing properly) 2- is PowerVM to run on top of CloudBurst? 3- if the above solution is applicable, is this some sort of HA solution (since the VM will run on top of multiple physical boxes, while the same physical box will run multiple live images) thanks for your help

  • Using multiple PaaS Vendors

    - by jpabluz
    I am developing a SaaS App, and I want to decide for a PaaS Vendor. Since one of my biggest concerns is uptime, is there an application or service, that allows me to use several PaaS Vendors (like Azure, Google App Engine, Amazon Web Services, etc.)? I want my application to be able to respond from one PaaS Vendor to another almost instantly without any downtime, to use the redundancy that this provides. This means that I need to be able to use the different services homogeneously.

  • How do I set up an sftp user to login with a password to an EC2 ubuntu server ?

    - by Doron
    Hello, I have an Ubuntu Server running on an EC2 instance. To login to that server I use a certificate file without any password. I've installed and configured vsftpd and created a user (let's call him "testuser") for which I've set a /bin/false ssh terminal so it will only be able to connect via sftp and upload/access files on his home directory. However - when I try to connect to the server from my computer, running sftp testuser@my-ec2-server I get Permission denied (publickey). Connection closed messages so I can't log in. How can I remove the certificate requirement for this user only (meaning, the "ubuntu" user will still have to use the certificate file to login via ssh), so normal sftp clients will be able to connect using a username and a password ? Thank you. PS Using Ubuntu Server 10.10 official AMI from canonical, 64bit on a micro instance.

  • vpn/Openvpn as a cloud service

    - by 8pipe
    I am working on creating a small cloud (any number of EC2 instances that can be deployed based on load) implementing a VPN as a service for the company I'm working for. This is basically a project gathering together various vpn resources under one aegis as a cloud based service. As a user of openvpn, I'm somewhat familiar with being able to connect, but I'm looking for resources to start this project. Essentially I need to be able to: run a certificate authority and manage keys to distribute to coworkers build an ami that handles openvpn as a service balance the load if necessary among machines instances as needed Any suggestions for tutorials, things to avoid, roadblocks I might not be seeing from a novice perspective, etc. or just help in visualizing this is appreciated.

  • netcat as a multithread server

    - by etuardu
    Hello, I use netcat to run a simple server like this: while true; do nc -l -p 2468 -e ./my_exe; done This way, anyone is able to connect to my host on port 2468 and talk with "my_exe". Unfortunately, if someone else wants to connect during an open session, it would get a "Connection refused" error, because netcat is no longer in listening until the next "while" loop. Is there a way to make netcat behave like a multithread server, i.e. always in listening for incoming connections? If not, are there some workarounds for this? Thank you all!

  • Eucalyptus / no bootable EBS yet - any alternatives to Eucalyptus?

    - by itgorilla
    I've read a couple of articles that Eucalyptus doesn't support bootable EBS yet. This is a problem since you can't make a backup form an instance like you a able on Amazon cloud or Rack Space Cloud. If you ever reboot the physical Ecalyptus sever that's running the node controller the instance is gone along with all your settings. Are there any alternatives to Eucalyptus or is just the only game in town when it comes to open source cloud?

  • Getting rid of your server in a small business environment

    - by andygeers
    In a small business environment, is it still necessary to have a central server? Speaking for my own company (a small charity with about 12 employees) we use our server (Windows Server 2003) for the following: Email via Microsoft Exchange Central storage Acting as a print server User authentication / Active Directory There are significant costs associated with running a server like this: Electricity, first for the server itself then for the air conditioning required (this thing pumps out a lot of heat) Noise (of which there is a lot) IT support bills (both Windows Server and Exchange are pretty complicated, and there are many ways they can go wrong) I've found ways to replace many of these functions with cheaper (better?) alternatives: Google Apps / GMail is a clear win for us: we have so many spam related problems it's not even funny, and Outlook is dog slow on our aging computers You can buy networked storage devices with built in print servers, such as the Netgear ReadyNAS™ RND4210 that would allow us to store/share all of our documents, and allow us to access printers over the network The only thing that I can't figure out how to do away with is the authentication side of things - it seems to me that if we got rid of our server, you'd essentially have a bunch of independent PCs that had no shared pool of user accounts / no central administrator. Is that right? Does that matter? Am I missing any other good reasons to keep a central server? Does anybody know of any good, cost-effective ways of achieving the same end but without the expensive central server?

  • Custom Windows AMI for Amazon EC2

    - by cutyMiffy
    Hello: I am new to the Amazon EC2 services and I am planning to host a Windows based vm on Amazon. I have lot of fuzziness about AMIs on Amazon. So my first question would be, am I be able to install softwares and frameworks(e.g. Silverlight, .NET, etc) on a existing Windows instance that I select? And if not, how can I create a custom AMI so that I can install these softwares that I need before I submit it to Amamzon and launch? Thanks a lot for your help :) Deeply appriciated

  • Optimum number of threads while multitasking

    - by Gun Deniz
    I know similar questions have been asked but I think my case is a little bit diffrent. Let's say I have a computer with 8 cores and infinite memory with a Linux OS. I have a calculation software called Gaussian that can take advantage of multithreading. So I set its thread count to 8 for a single calculation for maximum speed. However I really can't decide what to do when I need to do run for instance 8 calculations simultaneously. In that case should I set the thread count to 1(total 8 threads spawned in 8 processes) or keep it 8(total 64 threads spawned in 8 processes) for each job? Does it really matter much? A related question is does the OS automatically does the core-parking to diffrent cores for each thread?

  • EC2 instances keep becoming inaccessible via SSH, can I use elastic loadbalancer to check SSH connectivity?

    - by Rick
    This is mainly an issue for my development ec2 server as it seems that my instance keeps becoming inaccessible via SSH. It happened yesterday so I killed that one and started a new one and happened again later today. The server still works, my web application is accessible in a web browser but whenever I try to connect via SSH I get a pemrission denied (public key) error message in my terminal. I am 100% sure I am doing nothing wrong as I can create a new instance of the exact same AMI (its a personal custom AMI), change absolutely nothing, including using the same .pem key, and then am able to SSH into that new instance using the exact same command as before (just changing the IP address). I understand that ec2 can have issues but having this happen every day seems a bit odd.. I am using an m2.xlarge instance so I don't know if these tend to be unstable, in the past I have used a small instance and had it running for months with no problems which is why I find this so odd. I am looking into using loadbalancing but it seems the only "health" checks they offer is for http or tcp so I'm not sure if I can make it monitor for SSH connectivity. This is important for development as I may make 1-2 new pushes of an application a day and use SSH to do this. I have a designer that needs to have the app always accessible as he works with the front-end files to test output with the live application. Anyways, any advice / info is appreciated

  • DNS settings for SaaS in the cloud?

    - by Jeremy
    I am building a SaaS product. When a user signs up for an account they must select an alias for their site --------.getlaunchpoint.com. Right now I have an A record *.getlaunchpoint.com that points to the ip address server. However, with Azure I am not given an IP address. The suggested implementation is to make use of a CNAME. I need to create a CNAME for *.getlaunchpoint.com - getlaunchpoint.cloudapp.net GoDaddy does not support CNAME wildcards. Searching on Google I'm getting conflicting information... is CNAME wildcard a bad practice? I run into the same problem with Amazon EC2 if I want to make use of load balancers because you cannot tie a public IP address to an Amazon Load Balancer. Amazon also suggests the use of a CNAME. Any help would be appreciated.

  • How do I make a Windows virtual machine replicate to another datacenter/cloud?

    - by zippy
    We have a Windows 2008 VM running IIS and SQL Server Express (it's an all-in-one web application). We need to have another copy at our secondary datacenter site. What is the best way to do this? It doesn't have to be running all the time but it has to have almost the latest copy of the current VM. I took a look at VMWare Fault Tolerance and after the heart attack at the price I starting looking for another solution. If need be I wouldn't mind copying it over to a cloud VM provider, if I can find one that lets me copy my own VMs up and start them up without any conversion process.

  • Is there any way to distribute x264 encoding jobs across multiple computers (to increase the encodin

    - by Breakthrough
    Does anyone know of a current, active solution to encoding x264 videos across many computers (via the network) to increase encoding FPS? I heard in the past of the project x264farm; unfortunately, it is not actively developed anymore, and isn't compatible with newer x264 builds. I'm looking for a current solution, which is compatible with newer builds of x264. Just to note this, I'm a Windows user, so I'm only looking for Windows solutions (or at the very least, Linux). I've also seen the ELDER distributed encoder, but the quality varies depending on the settings you use - I'd prefer a solution similar to x264farm as noted above (the documentation outlines the encoding process), but one that is compatible with new(er) x264 builds, and is preferably actively developed. Final Edit: Unfortunately, the bounty for this question has expired, and I haven't found a decent solution for this. So if at any time someone finds a new, distributed encoding solution for x264 (or any h.264 coded, for that matter) - please answer this question! I'd love to discover an ideal method to make this work!
