Define grain interfaces, implement stateful grains with IPersistentState, and understand activation/deactivation lifecycle.

Configure cluster membership, grain storage providers, and deploy multi-region with geo-redundancy and failover.

Use Orleans streams for event processing, implement event-sourced grains, and coordinate distributed transactions with sagas.

Build real-time hubs, scale with Orleans or Redis backplane, and implement connection groups, streaming, and client diagnostics.
