A system and method for supporting configuration of dynamic clusters in an application server environment. The method can begin with providing, at one or more computers, including an application server environment executing thereon, a plurality of deployable resources which can be used within the application server environment, and one or more partitions, wherein each partition provides an administrative and runtime subdivision of the domain, wherein the system can associate one or more partitions with a tenant, for use by the tenant. The method can further provide a dynamic cluster for use by the one or more partitions, the dynamic cluster comprising an initial number of servers running within the dynamic cluster. The method can then receive, at an administration server to receive, a command; and then configure, via an API, the dynamic cluster.
