Built on top of Reliable Services, the Reliable Actor framework is an application framework that implements the virtual Actor pattern based on the actor design pattern. The Reliable Actor framework uses independent units of compute and state with single-threaded execution called Actors. The Reliable Actor framework provides built-in communication for Actors and pre-set state persistence and scale-out configurations.

As Reliable Actors itself is an application framework built on Reliable Services, it is fully integrated with the Service Fabric platform and benefits from the full set of features offered by the platform.
