Just heard from Amazon that they are going to provide a new web-service called Cloudformation. Its similar to making an AMI, but for the entire cloud! A user makes his/her own template for the entire cloud, which contains a resource stack, and just launch it on the fly. You can also make your own formation, and specify the dependencies between the resources. Cloudformation will figure out the rest! We are going to use it soon, maybe as soon as next week! I am excited, and if you are reading this, I guess you are too :) Stay tuned!
