A system, apparatus, method, and computer program product that provide a flexible and modular cloud IT service delivery solution model. The apparatus comprises a processor and computer-readable program code that defines a plurality of common capabilities that comprise operations. Those operations are configured to be invoked by a plurality of different processes on a plurality of different containers, and the plurality of common capabilities comprise a service delivery solution when invoked by a process from among the plurality of different processes. Further, the is processor configured to execute the computer-readable program code and to invoke the plurality of common capabilities with each of the plurality of different processes on the plurality of different containers. Accordingly, the apparatus may utilize different containers interchangeably in a plurality of different service delivery solutions and may expand and contract each of the plurality of different service delivery solutions by invoking greater or fewer processes on greater or fewer containers.
