Scalr: auto-scaling web app hosting in EC2 »

Scalr is a fully redundant, self-curing and self-scaling hosting environment utilizing Amazon’s EC2.

It allows you to create server farms through a web-based interface using prebuilt AMI’s for load balancers (pound or nginx), app servers (apache, others), databases (mysql master-slave, others), and a generic AMI to build on top of.

The project is still very young, but we’re hoping that by open sourcing it the AWS development community can turn this into a robust hosting platform and give users an alternative to the current fee based services available.

This looks like it could be great when it develops. I kind of think that Amazon themselves should be providing this kind of executive service to auto-scale and -heal an application deployed in their grid (and wouldn’t be surprised if they add it as their service matures).
