AWS – Migrate Linux AMI (EBS) using CloudyScripts

In a typical Amazon Web Services(AWS) Environment, Amazon Machine Images (AMIs) are strictly available in a certain region only. These AMIs cannot be moved from one region to another. Though the AMIs are shared within different Availability Zones of the same region. For this purpose, you can use a third party tool called as CloudyScripts.

CloudyScripts is a collection of tools to help you programming Infrastructure Clouds. The web-based tool is self explanatory and regularly updated. In case you find any bug, do not hesitate to email the owners right away.

Goto the CloudyScripts Copy AMI to different region tool.

AMI should be EBS-backed Linux AMI only. The AWS Access Key and Secret Key can be found at the Security Credentials page of your AWS Account. This information is unique to your account and can be misused. DO NOT share these details with anyone.

The key provided should be generated in the source and target region before using the tool. Provide the .pem key files.

AWS discourages use of “root” user for login into AWS EC2 Instances.

You may use different ssh users like, “ec2-user” for AWS Linux Instances or “ubuntu” user for Ubuntu instances.

Output will be displayed as:

Verify that the AMI is registered in the destination as Private to you i.e.owner.

If you opt to receive mail of the status, enter your email id in the status window.

AWS EBS-Backed Instance Backup &Restore

Starting with the 2009-10-31 API, Amazon Web Services (AWS) has a new type of Amazon Machine Image(AMI) that stores its root device as an Amazon Elastic Block Store(EBS) volume. They refer to these AMIs as Amazon EBS-backed. When an instance of this type of AMI launches, an Amazon EBS volume is created from the associated snapshot, and that volume becomes the root device. You can create an AMI that uses an Amazon EBS volume as its root device with Windows or Linux/UNIX operating systems.These instances can be easily backed-up. You can modify the original instance to suit your particular needs and then save it as an EBS-backed AMI. Hence, if in future you need the the modified version of instance, you can simply launch multiple new instances from the backed-up AMI and are ready to-go.

Following are the steps to be performed for backup/restoring of AWS EBS instance into/from an AWS AMI. Also brief steps for deletion of AMI backup are noted for reference.
 

EBS-instance to EBS-backed AMI

  • Go to AWS Management Console and in the My Instances Pane, select the instance which has to be backed up.
  • Right click the instance and select option Create Image (EBS AMI).
  • In the Create Image dialog box, give proper AMI Name and Description. Click on Create This Image button.
  • The image creation will be in progress. This will take sometime depending upon the number & size of volumes attached to the instance. Click on View pending image link. It will take you to the AMIs pane.
  • The AMI will be in pending state. It is important to note that this AMI is private to the account and not available for AWS public use.
  • If you select Snapshots from the Navigation Pane, then you can see that EBS volumes attached to the instance will be backed up as too.
  • Once the backup is done, the AMI will be in available state.

 

Restore from backup AMI into instance

In case, the running instance needs to be restored, use the latest backup AMI. To launch an instance from this AMI, right-click the AMI and select Launch Instance option. The Launch Instance Wizard will be displayed, perform the usual configurations and a new instance will be created containing all the data & configurations done before backup.

 

Delete AMI & Snapshots:

  • To delete any AMI, Right-click it and select De-register AMI.
  • Remember, deleting AMI doesn’t delete the EBS volume snapshots. Click on Snapshots from Navigation pane, search & select the snapshot(s) to be deleted. Right-click on the snapshot(s) and select delete snapshot option.

Cloud Computing Best Practices

In a recent article “Put Your Test Lab In The Cloud”, InformationWeek outlined the pros, cons and considerations you must take into account when talking about hosting test labs in the cloud. Using the cloud for this purpose is not necessarily a new idea, and it’s one that certainly makes a lot of sense; Replication of test results depends upon consistency across all variables, and putting a test lab in the cloud allows you to do that from anywhere or for anyone who needs to use it.

Indeed, the use of private or public cloud services, like Amazon Web Services, as a platform for software development & testing, is common practice for some businesses already. The benefits of using the cloud for this include the general positives of cloud, such as cost savings (in terms of the lack of start up cost as well as hardware upgrades, maintenance etc…
