NGINX Open Source - High-Performance Web Server & Reverse Proxy
The official repository for NGINX Open Source, a high-performance web server, reverse proxy, load balancer, and HTTP cache. Known for its stability, rich feature set, simple configuration, and low resource consumption.
Project Introduction
Summary
NGINX is a widely-used open-source software for web serving, reverse proxying, caching, load balancing, media streaming, and more. It's designed for maximum performance and stability, making it a cornerstone technology for many high-traffic websites and applications.
Problem Solved
NGINX addresses the challenges of building and operating high-traffic websites and applications, providing a robust solution for handling concurrent connections efficiently, scaling infrastructure, and improving application performance and security.
Core Features
Event-driven Architecture
Utilizes a highly efficient event-driven architecture to handle a massive number of concurrent connections with low memory footprint.
Reverse Proxy
Acts as a reverse proxy for HTTP, HTTPS, TCP, UDP, and other protocols, forwarding client requests to backend servers.
Load Balancing
Distributes incoming network traffic across a group of backend servers to improve performance and reliability.
Caching
Caches frequently accessed static and dynamic content to reduce the load on backend servers and improve response times.
Modularity
Supports modular architecture with a variety of modules for extended functionality (e.g., Gzip, SSL, HTTP/2, WebSocket proxying).
Tech Stack
Use Cases
NGINX's versatility makes it suitable for a wide range of applications, from serving small websites to powering large-scale distributed systems. Common use cases include:
Serving Static Assets
Details
Serving static content (HTML, CSS, JavaScript, images) directly and efficiently, reducing load on application servers.
User Value
Significantly improves website loading speed and reduces infrastructure costs.
Acting as a Reverse Proxy
Details
Routing client requests to backend application servers (like Node.js, Python/Django, Java/Spring), acting as a central point of access.
User Value
Provides a layer of security, simplifies backend management, and enables features like SSL termination.
Implementing Load Balancing
Details
Distributing incoming traffic across multiple instances of an application server to handle high loads and ensure continuous availability.
User Value
Ensures application stability under heavy traffic and improves overall system reliability and scalability.
API Gateway
Details
Functioning as an API Gateway to manage, secure, and route API traffic to various backend services.
User Value
Centralizes API management, improves security, and simplifies microservice architecture.
