#### Framed protocols

Framed protocols like http/2 don't lend themselves to blocking APIs. Each application-layer thread wants to do blocking I/O for a specific stream, but the streams are multiplexed on the socket. You can't just talk to the socket, you need to cooperate with the other application-layer threads that you're sharing it with.

- **Istiod** - The Istio control plane. It provides service discovery, configuration and certificate management. It consists of the following sub-components:

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.

	return makeBucketLocal(ctx, bucket, opts)
}

func (l localPeerS3Client) DeleteBucket(ctx context.Context, bucket string, opts DeleteBucketOptions) error {
	return deleteBucketLocal(ctx, bucket, opts)
}

// client to talk to peer Nodes.
type remotePeerS3Client struct {
	node  Node
	pools []int

	// Function that returns the grid connection for this peer when initialized.
	// Will return nil if the grid connection is not initialized yet.

for this time the Mouse was bristling all over, and she felt
certain it must be really offended.  `We won't talk about her any
more if you'd rather not.'

  `We indeed!' cried the Mouse, who was trembling down to the end
of his tail.  `As if I would talk on such a subject!  Our family
always HATED cats:  nasty, low, vulgar things!  Don't let me hear
the name again!'

The cashier gives you the number of your turn.

While you are waiting, you go with your crush and pick a table, you sit and talk with your crush for a long time (as your burgers are very fancy and take some time to prepare).

And then, there would be another program (in some cases it's another program, in some cases it could be the same TLS Termination Proxy) that would talk to Let's Encrypt, and renew the certificate(s).

The **TLS certificates** are **associated with a domain name**, not with an IP address.
