1. A method for workload deployment density management for a multi-stage computing architecture implemented within a multi-tenant computing environment, the method comprising: receiving by the device a request from a tenant of a multi-tenant computing environment executing in memory of a host computing system of one or more physical servers each with memory and at least one processor, to deploy an application instance of a computer program into a particular one of different nodes of the host computing system; determining from the request by the device an associated stage of a software lifecycle for the application instance; and, deploying by the device the application instance into one of the nodes depending upon an associated stage of the application instance so that each of the nodes hosts different application instances for different tenants of a common stage of the software lifecycle.
