Can anyone point me to the steps/resources that describe:
- How to deploy a JEE app on amazon-EC2
- Maintain changes to the meta-data of the app server (deploy new applications) after an instance reboot (probably using amazon-ebs)
Can anyone point me to the steps/resources that describe:
First check this out if you haven't already ran through it: http://docs.amazonwebservices.com/AmazonEC2/gsg/2006-06-26/ it'll give you an idea of how it all works.
With regard to running a jee app on EC2, you have a couple of choices - but they generally come down to the following recipe:
Now you can bundle the above into an ebs ami, or you can write a script (bash/sh/tcl) which applies those changes when your instance starts (which i prefer). The scripts allow you to modify what gets installed/started/moved around without having to rebundle your instance.
There's some great resources here: http://developer.amazonwebservices.com/connect/kbcategory.jspa?categoryID=100
Hope that helps.
If you start an ebs-booted instance, you do not need to care about persistency after a reboot (see http://aws.amazon.com/about-aws/whats-new/2009/12/03/amazon-ec2-instances-now-can-boot-from-amazon-ebs/) Concerning the deployment of JEE, I don't see any difference to deploying it on a non-virtual OS.
How to deploy a JEE app on amazon-EC2
You still deploy to an application server so it isn't really different. If you have more specific questions, please clarify. But have a look at Running JEE applications on Amazon EC2 and How to deploy a java web application on an ec2 instance.
Maintain changes to the meta-data of the app server (deploy new applications) after an instance reboot (probably using amazon-ebs)
If you use Amazon EBS, then you don't need to worry, Amazon EBS volumes are off-instance storage that persists independently from the life of an instance.
