ClusterCS is an all-inclusive management system for Linux based web servers, compatible with any type of VPS or Dedicated server, regardless of the infrastructure provider.
Its most distinctive feature is the HA Cluster builder that allows the building of high traffic and high availability Cluster infrastructures in minutes.
Another great feature is the ability to create dev environments and the entire migration between live and dev envs is automated. Further more, the developer can work exactly under the same URL of the main site, while the normal visitors get the live environment.
