These components include a System Registry that provides a global data storage; a Configuration manager that stores data locally on nodes of the clustered environment and globally within the System Registry; a Liveness component to provide status of communications paths of the cluster; a Group Services component that provides services to one or more other components of the clustered environment; and a Resource Management component that communicates with one or more resource controllers of the clustered environment. Each of the components of the clustered environment has one or more data and/or functional dependencies on one or more other components of the environment. However, relationships between the components are created such that the data and functional dependencies form an acyclic graph (i.e., a cycle of dependency relationships is avoided). ## Claims ### Claim 1 A computer implemented method of automatically configuring clusters of a computing environment, said computer implemented method comprising: initiating, by a node to be added to a cluster of said computing environment, an obtaining of configuration data of one or more resources of said node;
