Can Java Enterprise Edition applications on AWS EC2

Question

I aim at doing the following:

First deploy a Java EE app on amazon-EC2. Second, keep changes to the meta-data of the app server after an instance reboot. How does one proceed with it?

Answer 1

It would be good if you start with this:
http://docs.aws.amazon.com/gettingstarted/latest/awsgsg-intro/intro.html
This link should give you the complete the know-how.

And yes, it is possible to deploy your Java EE to EC2. These are the probable steps:
1.    Begin by starting an instance
2.    Then Install a Java EE application server
3.    Install your application (war/ear) into the application server
These the options you have
1.you can bundle the above into an ebs ami,  
2. you can write a script (bash/tcl) which will apply these changes when your instance initiates. The scripts enables modification of what gets installed/started/moved around without having to rebundle your instance.
