# webrtc-zero-downtime-restart

webrtc-zero-downtime-restart is a simple Pion WebRTC broadcast server that can be restarted

without disconnecting users. All the WebRTC state is suspended to disk. The

next time the process is started that information is read into memory. All

the remote PeerConnections will be unaware that they are even connected to a new

process. This gives us the following benefits.

### Painless Deploys

No more migrating users to a new process when you want to deploy code. At anytime you

can replace the binary you are running and no users will be impacted. You don't need

to implement extra signaling/error handling for your deploy process.

### Easier Scaling

Move clients to an entirely different host without them knowing. You can do this with

zero interruption in service or additional signaling.

### Greater Resiliency

Since server state is constantly being written to disk you don't need to worry about

crashes anymore. If you server goes down (and then restarts) it will automatically resume

the last known good state.

## Running

Execute `go run github.com/Sean-Der/webrtc-zero-downtime-restart@latest`.

This will start the server. On startup the server will print.

```

Open http://localhost:8080 to access this demo

```

You can then access it at [http://localhost:8080](http://localhost:8080). The first user to connect will broadcast

their webcam. Every user after can watch the broadcasted video.

At anytime you can start+stop the process in your terminal. Users will not be disconnected and will

be able to continue talking when the process is started again.

## What is next

This demo uses reflection to access internal Pion WebRTC APIs. We will be working on designing the final

APIs for the next major release of Pion WebRTC. We would love your feedback ideas either on the

repo or [Slack](https://pion.ly/slack)
