Ruby, Rails, and Randomness

Intridea is officially open-sourcing Scalr - a redundant, self-curing, and self-scaling hosting environment build on top of Amazon's EC2.

Scalr utilizes EC2 to provide a multi-tiered hosting environment with pre-built images for load balancers, database servers, and application servers. Designed with flexibility in mind, users can further customize each type of machine to use as nodes in their server farm or customize a generic base image for any number of purposes. The application monitors and maintains the server farm by reconfiguring the entire cluster when machines fail or when new machines are inserted. Additionally Scalr can be setup to replace failed machines and scale up and down based on user configured thresholds.

The system was initially designed for MediaPlug, a white label audio, video, and image transcoding service that needed to scale based on customer demand.

The project can be found at http://scalr.intridea.com

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 give users an alternative to the current fee based services available.
