Stateless Server

Running a stateless server means that all persistent data is stored outside of the server.

Why is it Important?

• Stateless servers are easier to deploy/upgrade.

• Stateless servers are much easier to recover in case something breaks.

• Managing persistent datastores correctly requires significant amount of engineering effort per datastore.

• Stateless servers can be scaled independently from their datastore.

• Multiple pods of your service can disappear (and lose their non-persistent state) at any time.
