• AMIs in Amazon EC2

  - by Jack of Trades

  I really like the Amazon EC2 environment, and thought I'll spend a bit of time playing around with various types of public (Windows!) AMI servers. But testing has been a bit, well, questionable. Some of my findings: It's very difficult to know what exactly a specific public EC2 image is supposed to be doing. Many images come with little to no information. I can't seem to find the passwords to log onto various windows images. Why are they public if they can't be used!? Lots of images are based on S3, and not EBS backed. This is very annoying, as S3 takes a lot longer to do pretty much anything (stop, image etc.) I am only testing images here, so of-course I don't question the value of S3 for other attributes. The description of what an image does is almost useless and many times confusing. Have others come across these EC2 issues. Again, my interest was to just play around with public images for testing/experimentation/etc, and therefore these issues may not be too relevant for more normal EC2 deployment uses.

• Why can't I create an Alias Resource Record Set for an EC2 instance

  - by praterade

  I have been working with AWS for over a year, setting up EC2 instances, domains, ELBs, etc. When I want to assign a subdomain to an EC2 instance, I have to create an elastic IP (that I pay for), then assign a CNAME record to that elastic IP. When I want to assign a subdomain to an ELB (load balancer) instance, I just create an alias resource record set to the ELB. I've read over the docs and don't understand why AWS doesn't support aliasing to instances. Am I missing a key concept here? Wouldn't it be simpler to just alias EC2 instances and skip the whole elastic IP bit?

• Switching from Amazon EC2 instance-store to EBS Volume

  - by Adam

  Hi, I have an Amazon EC2 instance that is using an instance-store as its root device. It has no EBS volumes attached to it. It has a database and a running web application on it. If I understand correctly this is a bad setup as I would lose all the data on the instance if it were to reboot. I would like to correct this mistake. I'd like to move all the data on the running instance to a new EBS volume and make that new volume the root device. How do I go about doing this? Thanks!

• How do I host multiple SSL websites on a single EC2 instance using Amazon Elastic Load Balancers?

  - by Developr

  If I have 3 separate websites which all require SSL (separate certificates) that I want to host on the same EC2 instance(s) across multiple availability zones so that we have the ability to scale and be highly available, how do I achieve this using ELBs in my Amazon VPC? Each site requires a separate IP address, so I have added multiple private IPs to the EC2 instance, but I am unsure how to bind the ELB to a certain IP on the instance. I was also able to setup multiple ELB pointing to the same instance, but again, I am not seeing any way to bind each ELB to a separate IP on the instance. If this is not possible, what is the best option? Run each site on a separate EC2 instance / ELB combo (expensive and harder to maintain) Give each site a separate public IP and use Route 53 to do the load balancing (seems like a hack) Use a different load balancer option such as HAProxy that should be able to work like a normal load balancer appliance. Please help!

• Managing Many External Hosts Using EC2 and Route 53

  - by futureal

  Looking for a "best practice" answer to managing externally-addressable hosts using the combination of Amazon EC2 and Amazon Route 53, without using Elastic IPs for each host. In my scenario I will have 30+ hosts that need to be accessible from outside EC2, so directly using internal DNS will not work. In the past, I have addressed hosts by assigning an elastic IP to that host (let's say, 55.55.55.55) and then creating an associated A record. For example, let's say I want to create "ec2-corp01.mydomain.com" I might do: ec2-corp01.mydomain.com. A 55.55.55.55 300 Then on that EC2 instance, I would assign the Elastic IP of 55.55.55.55, and everything works fine. Of course, to make this work, I need to have one Elastic IP per instance, which is something I'd like to avoid if possible; I'd like the infrastructure to be more dynamic. So my thought is to try something like: Create a script that queries the internal EC2 tools to determine an instance's private hostname On instance boot, call that script to determine its hostname, and then using the command-line Route 53 interface to find and update that hostname to its current internal hostname Since the host will have a relatively low TTL (let's say 300 as above, or 5 minutes) it should take effect pretty quickly Is this a good idea? Is there a better or more widely accepted way to handle it? If it IS a good idea, what type of record should I be creating? A CNAME that points to the internal host, like ec2-55-55-55-55.compute-1.amazonaws.com? Is an A record better or worse? Thanks!

• Check If You Are Eligible To Try Amazon Fire TV Free for 30 days

  - by Gopinath

  Re/Code first broke the story of Amazon offering its customers to try Amazon Fire TV free for 30 days. The Amazon Fire TV costs $99 but with this offer you get a chance to try it for 30 days without paying any money. After 30 days if you are interested you can keep it with you by paying $99 otherwise you can return it to Amazon. All the costs associated with shipping to your home as well as returning back to Amazon are covered by the offer, which means it’s a real FREE offer to try! This offer is not available for everyone, but selected customers are receiving emails from Amazon. If you are interested to try free Amazon TV either you may wait to receive an offer email or click on this link to check if you are eligible. I verified it today and it says that I’m not eligible for this offer. Try your luck and all the best.

• Is it better to have AWS EC2 and RDS is the same Availability Zone?

  - by Dan

  I run a web app in an AWS EC2 instance and the database for the app in an RDS instance both in Amazon Web Services Region East-1. However, one of them is in Availability Zone 1a and the other is in 1d. Am I getting all the speed benefits of having both instances in the same "data center" (East-1) even if they are in different Availability Zones, or can I optimize by moving them to the same Availability Zone?

• Is it safe to use S3 over HTTP from EC2, as opposed to HTTPS

  - by Marc

  I found that there is a fair deal of overhead when uploading a lot of small files to S3. Some of this overhead comes from SSL itself. How safe is it to talk to S3 without SSL when running in EC2? From the awesome comments below, here are some clarifications: this is NOT a question about HTTPS versus HTTP or the sensitivity of my data. I'm trying to get a feeling for the networking and protocol particularities of EC2 and S3. For example Are we guaranteed to be passing through only the AWS network when communicating from EC2 to S3 Can other AWS users (apart from staff) sniff my communications between EC2 and S3 Is authentication on their api done on every call, and thus credentials are passed on every call? Or is there some kind of authenticated session. I am using the jets3t lib. Feedback from people with some AWS experience would be appreciated. Thanks Marc

• How can I create multiple identical AWS EC2 server instances with large amounts of persistent data?

  - by mojones

  I have a CPU-intensive data-processing application that I want to run across many (~100,000) input files. The application needs a large (~20GB) data file in order to run. What I would like to do is create an EC2 machine image that has my application and associated data files installed boot up a large number (e.g. 100) of instances of this image split my input files up into 100 batches and send one batch to be processed on each instance I am having trouble figuring out the best way to ensure that each instance has access to the large data file. The data file is too big to fit on the root filesystem of an AMI. I could use Block Storage, but a given Block Storage volume can only be attached to a single instance, so I would need 100 clones. Is there some way to create a custom image that has more space on the root filsystem so that I can include my large data file? Or is there a better way to tackle this problem?

• Fail rate of EBS snapshots and AMIs?

  - by user784637

  According to Amazon the fail rate of EBS volumes is: As an example, volumes that operate with 20 GB or less of modified data since their most recent Amazon EBS snapshot can expect an annual failure rate (AFR) of between 0.1% – 0.5%, where failure refers to a complete loss of the volume http://aws.amazon.com/ebs/ However, I was curious to know the fail rate of EBS snapshots and private AMIs that a system admin would take. Since the EBS snapshots and AMIs are stored in Amazon s3, is it safe to assume that the likelihood you cannot rollback to a previous snapshot or AMI the same likelihood that a file gets lost in s3? Amazon S3’s standard storage is: ... Designed to provide 99.999999999% durability and 99.99% availability of objects over a given year. http://aws.amazon.com/s3/

• Amazon S3 Tips: Quickly Add/Modify HTTP Headers To All Files Recursively

  - by Gopinath

  Amazon S3 is an dead cheap cloud storage service that offers unlimited storage in pay as you use model. Recently we moved all the images and other static files(scripts & css) of Tech Dreams to Amazon S3 to reduce load on VPS server. Amazon S3 is cheap, but monthly bill will shoot up if images/static files of the blog are not cached properly (more details). By adding caching HTTP Headers Cache-Control or Expires to all the files hosted on Amazon S3 we reduced the monthly bills and also load time of blog pages. Lets see how to add custom headers to files stored on Amazon S3 service. Updating HTTP Headers of one file at a time The web interface of Amazon S3 Management console allows adding custom HTTP headers to one file at a time  through “Properties”  window (to access properties, right on a file and select Properties menu). So if you have to add headers to 100s of files then this is not the way to go! Updating HTTP Headers of multiple files of a folder recursively To update HTTP headers of multiple files in a folder recursively, we can use CloudBerry Explorer freeware or Bucket Explorer trail ware applications. CloudBerry is my favourite as it’s a freeware and also it’s has excellent interface to access Amazon S3 from desktops. Adding HTTP Headers with CloudBerry application is straight forward – right click on the required folders and choose the option “Set HTTP Headers”. Download CloudBerry Explorer This article titled,Amazon S3 Tips: Quickly Add/Modify HTTP Headers To All Files Recursively, was originally published at Tech Dreams.

• Reducing latency for different geographic regions on Amazon Cloud

  - by Shoaibi

  I have got an application which has three components Application code : Amazon EC2 US-EAST-1 instance Application images, and other static data : Amazon S3 with CloudFront Application Database : Amazon RDS In short i need something like Cloud Front for EC2. In long, people using this application from a different region say middle east will have faster static content downloading due to Cloud Front but there would be a lot of latency in communicating to EC2 instance. I want to use a budget friendly way of enhancing this. Launching Amazon Instances in every region that offer is sure a choice, but isn't really cheap, so would try to avoid it unless its last resort. Also say if my clients also need to communicate to the RDS database directly, is there some kind of solution which gives that kind of functionality mentioned above, but for RDS?

• ssh timeout issue connecting to an EC2 instance on OS X

  - by mamusr

  I am new to AWS and not a networking expert but curious to know more about it. I created a VPC with a public subnet only. Then i created an EC2 instance using an Ubuntu 14.04 64-bit pv AMI image (ami-e84d8480) as well generating the key pair needed to connect to it through ssh. I followed amazon's instructions to connect to an EC2 instance via ssh which did not work. Here is my attempted input and debug log: Running on OS X 10.9.4 user$ ssh -vvv -i key.pem [email protected] OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011 debug1: Reading configuration data /etc/ssh_config debug1: /etc/ssh_config line 20: Applying options for * debug1: /etc/ssh_config line 102: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to xxx.xxx.xxx.xxx [xxx.xxx.xxx.xxx] port 22. debug1: connect to address xxx.xxx.xxx.xxx port 22: Operation timed out ssh: connect to host xxx.xxx.xxx.xxx port 22: Operation timed out To attempt to resolve the issue: I enabled the SSH port. Tried different usernames other than ubuntu, like ec2-user and root. Initially set an inbound ssh rule in the security group to connect to only my ip address. When that did not work, i changed it to allow any ip to connect. But those actions did not fix the problem. Here are my guesses as to what i am missing in getting the EC2 instance connection to work. My etc/ssh_config file may be preventing the connection from taking place. I may have missed an important networking detail when setting up the VPC. I do not have a public ip address specified for the instance. I am connecting through the private ip address. My questions for the community: Am i going about it the wrong way connecting to the instance through the private ip address? if so, do i need to specify a public ip address for it to connect or some other method?

• 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.

• Automatically Login & Startup A Windows Program On Amazon's EC2 Service

  - by darkAsPitch

  How can I automatically start a program on Amazon's EC2 Windows 2008 web servers? For example, if I wanted to test the "Digg effect" on a web page of mine, how could I open 100 windows 2008 servers at once, each loading one (or two?) instances of the firefox web browser? I have placed a sample batch file in the windows startup folder that echos the time it was called, but it is only started when I actually login remotely via the remote desktop protocol. I don't want to have to login to 100 servers to get my software to run :P What can I do? I am using this Windows 2008 Datacenter, Amazon-supplied AMI specifically: ami-a2698bcb

• I/O intensive MySql server on Amazon AWS

  - by rhossi

  We recently moved from a traditional Data Center to cloud computing on AWS. We are developing a product in partnership with another company, and we need to create a database server for the product we'll release. I have been using Amazon Web Services for the past 3 years, but this is the first time I received a spec with this very specific hardware configuration. I know there are trade-offs and that real hardware will always be faster than virtual machines, and knowing that fact forehand, what would you recommend? 1) Amazon EC2? 2) Amazon RDS? 3) Something else? 4) Forget it baby, stick to the real hardware Here is the hardware requirements This server will be focused on I/O and MySQL for the statistics, memory size and disk space for the images hosting.

• Amazon EC2 root defaults on EBS

  - by CodeShining

  I'm trying to understand why when launching a new instance Amazon defaults to EBS (8gb root) instead of instance storage. Why do they sell instance storage then if it's not used also to boot the base system? Is it safe to uncheck delete on termination, make it bigger (~50GiB) and keep all files on that EBS instead of creating a new one to make sure data will persist and it will also be usable by another instance?

• Installing an EC2 (EBS based) instance on another AWS account

  - by imaginative

  We're moving from one AWS account to another. I have a couple of EC2 instances I would like to move over. These instances are EBS based. Googling around, I'm seeing all sorts of convoluted answers for how to appropriately launch this EBS based instance on a new account. Surely there has to be a simple way of going about this. As of right now, what I have done so far is backup the EB2 Volume as a snapshot. I then altered the permissions of the snapshot to allow the new AWS account number to be able to access it. I am not sure where to go from here. Do I have to create an image from the EBS snapshot? Upload it to S3? What's the next step(s)?
