How to secure your websocket connections by mehul mohan?

(Just like you have access to req object for HTTP requests.) This is a no-brainer, but still needs to be said. Use wss:// instead of ws://. This adds a security layer over your communication. Use a server like Nginx for reverse proxying websockets and enable SSL over them.
Accordingly, what do you need to know about WebSocket?
WebSocket is a relatively new technology that enables a persistent connection between client and server over TCP protocol. In other words, it allows bi-directional socket connections to a server, where both server and client can send the data at any time. It is available in HTML5 and JavaScript and is fully explained here.
Besides, how to secure your WebSocket connections with SSL? This is a no-brainer, but still needs to be said. Use wss:// instead of ws://. This adds a security layer over your communication. Use a server like Nginx for reverse proxying websockets and enable SSL over them. Setting up Nginx would be a whole another tutorial.
Thereof, what should be the URL of the WebSocket constructor?
The WebSocket constructor accepts one required and one optional parameter: The URL to which to connect; this should be the URL to which the WebSocket server will respond. This should use the URL scheme wss://, although some software may allow you to use the insecure ws:// for local connections.
And, which is implicit in establishing a WebSocket connection?
Establishing a WebSocket relies on the HTTP Upgrade mechanism, so the request for the protocol upgrade is implicit when we address the web server as ws://www.example.com or wss://www.example.com. Once you've opened your connection, you can begin transmitting data to the server.

What's the maximum number of websocket connections per machine?

Port numbers are 16 bit, which means we have a theoretical limit of 65536 connections per WebSocket server process. In our example, we had four WebSocket server processes, so that would allow us to handle a maximum of 65536 local ports * 4 peer IPs = 262144 WebSocket connections per machine.

How many concurrent websocket connections does aws have?
