# Server Workers - Uvicorn with Workers

Let's check back those deployment concepts from before:

* Security - HTTPS
* Running on startup
* Restarts
* **Replication (the number of processes running)**
* Memory
* Previous steps before starting

Up to this point, with all the tutorials in the docs, you have probably been running a **server program**, for example, using the `fastapi` command, that runs Uvicorn, running a **single process**.

	subrouter.Methods(http.MethodPost).Path(peerRESTVersionPrefix + peerRESTMethodDevNull).HandlerFunc(h(server.DevNull))

	logger.FatalIf(consoleLogRPC.RegisterNoInput(gm, server.ConsoleLogHandler), "unable to register handler")
	logger.FatalIf(deleteBucketMetadataRPC.Register(gm, server.DeleteBucketMetadataHandler), "unable to register handler")
