System and method for logical configuration of distributed systems
A logical configuration manager includes a persistent storage for storing a configuration specification for a distributed system. The logical configuration manager also includes a node configuration generator that makes a first determination that the configuration specification includes a logical portion for the distributed system; in response to the first determination, generates node configurations for nodes of the distributed system based, in part, on the logical portion; and orchestrates application of the node configurations to the nodes of the distributed system. Orchestration of the application of the node configurations to the nodes of the distributed system places the distributed system in a state that complies with the logical portion of the configuration specification.
