1. An information processing system for migrating a legacy application to a multi-tenant computing environment, the information processing system comprising: memory; a processor communicatively coupled to the memory; and a resource manager communicatively coupled to the memory and the processor, the resource manager configured to perform a method comprising: analyzing a set of attributes associated with the legacy application; determining, based on analyzing the set of attributes, if the legacy application satisfies a plurality of migration criteria for migrating the multi-tenant computing environment; in response to determining that the legacy application failing to satisfy the plurality of migration criteria, notifying a user that the legacy application cannot be migrated to the multi-tenant computing environment; and in response to determining that the legacy application satisfying the plurality of migration criteria: instantiating at least one virtualized computing container on a host system in a multi-tenant computing environment; executing an instance of the legacy application within the virtualized computing container, the legacy application being initially configured to run on premise and serve one tenant at a time, and where the virtualized computing container securely isolates the executing instance of the legacy application from other executing instances of the legacy application; sending, based on the executing, at least one request received from a first client to the instance of the legacy application; and quiescing the virtualized computing container based on at least one quiescing criterion having been satisfied by the instance of the legacy application.
