Scalr - Scalable Web Sites with EC2

Dave Naffis of Intridea wrote to tell me that they have released Scalr in open source form. Scalr is a fully redundant, self-curing, self-hosting EC2 environment.

Using Scalr you can create a server farm using prebuilt AMI's for load balancing (either Pound or nginx), web servers, and databases. There's also a generic AMI that you can customize and use to host your actual application.

Scalr monitors the health of the entire server farm, ensuring that instances stay running and that load averages stay below a configurable threshold. If an instance crashes another one of the proper type will be launched and added to the load balancer.

Download the code, take a look at the diagrams, or (always the last resort) read the installation instructions.

Jeff,

This is really powerful especially if you take advantage of the new availability zones.
