Deploy on AWS with Lambda

Is it possible to deploy it to AWS with Lambda and API Gateway?

Absolutely, however in case of this example to work there, singling server would need to be updated a little bit, to meet requirements of AWS Lambda and API Gateway. The state has to be persisted somewhere, in a database, so you can track each of the connected clients.

The application is composed of the WebSocket API in API Gateway that handles the connectivity between the client and servers (1). Two AWS Lambda functions react when clients connect (2) or disconnect (5) from the API. The sendMessage function (3) is invoked when the clients send messages to the server. The server sends the message to all connected clients (4) using the new API Gateway Management API. To track each of the connected clients, use a DynamoDB table to persist the connection identifiers.

Thank you very much for the info Rafal.

And appart from Lambda, API Gateway, RDS database (or SNS) we do not need any streaming server in the middle because it is peer to peer right?

[vardius]

Yes, the only thing you need is a signalling server (in this case it would be API Gateway)

I set up some simple explanation how you can implement your own signaling channel

let me know if it need improvements
