Web Sockets v/s HTTPS

HTTP and Web Socket both are communication protocols used in client-server communication.

HTTP/HTTPS:

HTTP is essentially a request/response protocol in the client-server computing model, and the primary communication mode of the World Wide Web.
The HTTP protocol is unidirectional protocol works on the top of TCP protocol which is a connection-oriented transport layer protocol, we can create the connection by using HTTP request methods after getting the response HTTP connection get closed.
When we do not want to retain a connection for a particular amount of time or reusing the single connection for transmitting the data, HTTP connection is slower than the WebSocket..

WebSocket:

WebSocket is a bidirectional communication protocol that can send the data from the client to the server or from the server to the client by reusing the established connection channel. The connection is kept alive until terminated by either the client or the server.
One notable advantage of using WebSockets is, almost every browser supports WebSockets.
Almost all the real-time application like (trading, monitoring, notification) services uses WebSocket to receiving the data on a single communication channel.

• Bi-Directional protocol
• Full Duplex communication
• Single TCP connection
• Good security model

All the frequently updated applications used WebSocket because it is faster than HTTP Connection.

Conclusion:

WebSockets will be the better choice in the context of realtime`, ongoing communication.
WebSocket uses HTTP as the initial transport mechanism, but keeps the TCP connection alive after the HTTP response is received so that it can be used for sending messages between client and server.
