Few months ago, I graduated as a Systems Engineer (Which in Peru would be the equivalent to Computer Science in other countries) with my thesis "Designing a Model to Implement a High Availability Cluster for Web Servers". You can obtain more information about it here [1].
The thing is, after doing it, i realized that it would be great to have an application to implement and manage LVS Based Clusters (Modify config files, restarting servers, creating new configurations, and all that's involved with that) from a centralized server.
This means, that it would be great to configure and manage all the servers in the cluster configuration, from one single server. This way, LVS based clusters would be easier to manage, and we would also popularize Ubuntu in Cluster Implementations, because we would have a tool that will make things easier.
This idea, also extends to managing DRBD data servers, and managing any kind of heartbeat configurations, and all that could be needed to implement/manage LVS Based Clusters.
