Methods, systems and computer readable media for self-replicating cluster appliances

The subject matter described herein includes methods, systems, and computer readable media for self-replicating cluster appliances. A method for self-replicating cluster appliances includes at a controller node configured for controlling a cluster of one or more network testing and/or visibility nodes: receiving node information associated with a first computing node, wherein the first computing node includes a preconfigured operating system; determining, using the node information, operating system data for configuring the first computing node to be in the cluster; and providing, via a communications interface, the operating system data to the first computing node. The method also includes at the first computing node: receiving the operating system data; and using the operating system data to configure the first computing node to be in the cluster and to provide at least one network testing or visibility service.
