I've been working on a proof of concept for setting up an EC2 instance to act as a hot backup for a website. If all goes well we will be working on a larger scale deployment. It is still in the heavy development stage but is successfully running a LAMP based web application.

I actually remembered to document the whole process and posted it to: http://prolucid.com/node/33

All in all i'm really impressed with EC2. Amazon did a nice job with the documentation and made it quite feature rich. I was unaware of a few of the limitations, particularly how rigid the system is in how your file system is setup and also on what kernel you use. That being said, i was successfully able to create a Centos 5.2 AMI running the LAMP stack from scratch. I was also able to script it's creation and deployment which was really impressive. I'll continue to write about how it works out.
