WebSockets vs HTTP-2

API Monitoring to WebSockets vs HTTP-2

We've covered API Monitoring in our previous session. Now, let's shift our focus to a fascinating topic: WebSockets vs HTTP-2!

WebSocket: Overview

WebSocket is a protocol that enables full-duplex communication between a web client and a web server, allowing for real-time data exchange.

WebSockets: Full Duplex Communication

WebSockets support bi-directional communication. Both the server and client can send and receive messages simultaneously, providing a more responsive and interactive experience.

HTTP/2: Overview

HTTP/2 is a major revision of the HTTP protocol, designed to improve efficiency, performance, and security.

HTTP/2: Features

HTTP/2 introduces features like request multiplexing, server push, and binary encoding, resulting in reduced latency and improved network utilization.

HTTP/2 vs HTTP/1.1

HTTP/2 outperforms HTTP/1.1 in terms of speed, efficiency, and mobile experience. It's particularly beneficial for applications requiring frequent updates.

Comparison: HTTP/2 vs WebSockets

WebSockets and HTTP/2 serve different purposes. WebSockets focus on real-time communication, while HTTP/2 optimizes general web traffic.

When to Use WebSockets vs HTTP/2

WebSockets are ideal for real-time applications like chat, gaming, and financial trading. HTTP/2 is suitable for websites, APIs, and content delivery.

HTTP Long-polling

HTTP long-polling is a technique that simulates full-duplex communication by repeatedly sending HTTP requests to the server.

Server-Sent Events (SSE)

Server-Sent Events allow the server to push data to the client without the client explicitly requesting it.

WebRTC DataChannel

WebRTC DataChannel is a feature of the WebRTC API that provides bi-directional data transfer between peers in a web browser.

WebSocket Security

WebSockets can be secured using TLS (Transport Layer Security) to encrypt data transmission and prevent unauthorized access.

HTTP/2 Security

HTTP/2 provides enhanced security over HTTP/1.1 with mandatory TLS encryption and support for HTTP Strict Transport Security (HSTS).

Performance Comparison: WebSockets vs HTTP/2

WebSockets generally have lower latency and higher throughput compared to HTTP/2 for real-time applications and scenarios involving frequent message exchanges.


WebSockets and HTTP/2 are powerful technologies with distinct use cases. Understanding their differences and strengths will enable you to make informed decisions for your web applications.
