Restate

Restate sits in front of your services as a single-binary server written in Rust. It persists every invocation and the results of side effects in a journal, so handlers resume exactly where they left off after crashes, deploys or timeouts. Beyond workflows, Restate offers durable RPC between services, virtual objects (keyed, stateful entities with single-writer semantics), durable timers and promises, and idempotent request handling. Services run anywhere, including containers, Kubernetes or serverless platforms like AWS Lambda.
