In some examples, a system receives, from a requesting entity, input information relating to a program to be deployed on a server system. The system establishes, based on the input information, an environment in the server system, where the environment is based on interaction with a subsystem of the server system, the subsystem of the server system to support one or more of fault tolerance for the program or scalability of the program in the server system. After establishing the environment of the subsystem of the server system, the system sends response information to the requesting entity, the response information useable by the requesting entity to manage the program when executed in the server system.
