GLU's goal is to be able to automate the deployment of any kind of applications accross many nodes. Although written in groovy/java, the type of applications that can be deployed through GLU is not limited to java applications. GLU monitors the running applications ("runtime state") of servers, compares it to a "desired state", and can (automatically) execute delta commands to 'fix' the delta.
