The Globule collaborative CDN is an open-source third-party module for the Apache Web server that allows a given server to replicate its documents to other Globule servers. It takes care of maintaining consistency between the replicas, of monitoring the servers, and of automatically redirecting clients to one of the available replicas. Globule also supports the replication of PHP documents. It runs on Unix and Windows systems.
Note: This project is now discontinued, and is no longer maintained. You may want to take a look at the ConPaaS project instead.
