# 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**.

func registerBootstrapRESTHandlers(gm *grid.Manager) {
	server := &bootstrapRESTServer{}
	logger.FatalIf(serverVerifyHandler.Register(gm, server.VerifyHandler), "unable to register handler")
}

// client to talk to bootstrap NEndpoints.
type bootstrapRESTClient struct {
	gridConn *grid.Connection
}

// Verify function verifies the server config.

	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")

	if globalIsDistErasure {
		logger.Startup(color.Bold(banner))
	}
	logger.Startup(color.Bold(MinioBannerName))
	if err != nil {
		if globalConsoleSys != nil {
			globalConsoleSys.Send(GlobalContext, fmt.Sprintf("Server startup failed with '%v', some features may be missing", err))
		}
	}

	if !globalSubnetConfig.Registered() {
		var builder strings.Builder
		startupBanner(&builder)
		logger.Startup(builder.String())
	}

	_, ok := obj.(*erasureServerPools)
	if !ok {
		t.Fatal("Unexpected object layer detected", reflect.TypeOf(obj))
	}

	// Tests for Erasure object layer initialization.

	// Create temporary backend for the test server.
	nDisks = 16
	disks, err = getRandomDisks(nDisks)
	if err != nil {
		t.Fatal("Failed to create drives for the backend")
	}
	defer removeRoots(disks)

Multiple instances can be obtained by naming additional ones:

```
class MyTest(
  private val server: MockWebServer,
  @MockWebServerInstance("server2") private val server2: MockWebServer,
  @MockWebServerInstance("server3") private val server3: MockWebServer
) {

	ftp "goftp.io/server/v2"
