Abstract

Embodiments facilitate the efficient handling of service requests by a Platform-as-a-Service (PaaS) infrastructure. The platform may comprise a central controller communicating with a plurality of execution agents on one or more hosts. The central controller may parse client requests manipulating application state (e.g., scale, start, stop app, clear) into a sequence of fine-grained instance requests (e.g., start, stop, stop all, clear) that are distributed to the application program interfaces (API) of execution agents on the platform. The central controller may assign a priority to the fine-grained requests. The priority may take into consideration one or more factors including but not limited to: request creator (user, system); operation type (start, stop, stop all, clear); instance number; sequence number of the fine grained request within the original received request; hierarchy level (organization, space); and application. Fine-grained requests may be distributed by a scheduler to a queue of the execution agent.
