We also put a lot of energy into making operations of Restate as simple as possible. We learned it the hard way when building Apache Flink that operating a distributed system is challenging especially if it relies on other external systems like ZooKeeper. Therefore, Restate comes as an all-batteries-included single binary that does not need any external dependencies. So you don't have to understand and operate multiple systems. Moreover, you can start with a single node deployment and later turn it into a multi-node deployment by "simply" starting new processes that connect to the existing cluster.

Restate itself sits in between your services and your user's requests. It is designed to push invocations to your service endpoints which allows it to play nicely together with serverless platforms such as AWS Lambda, Cloud Run functions, etc.
