Apache Traffic Server: Fast Caching Proxy

Apache Traffic Server is an open-source caching proxy server that improves web server performance by caching frequently accessed content and handling requests, offering a fast, scalable, and configurable solution.

What is Apache Traffic Server?

Apache Traffic Server (ATS) is an open-source caching proxy server that is designed to improve web server performance, scalability, and reliability. ATS works by caching frequently accessed content in memory, which allows the content to be served quickly without requiring requests to be handled by web servers.

Some key features and benefits of ATS include:

  • Speed and performance - ATS is very fast and can handle thousands of requests per second while using fewer server resources than web servers.
  • Scalability - ATS scales well on modern multi-core hardware, allowing it to support high traffic levels.
  • Reliability - If a web server goes down, ATS can continue to serve cached content, improving uptime.
  • Configurability - ATS has many configuration options to tune performance for specific use cases or traffic patterns.
  • Load balancing - ATS has load balancing capabilities to distribute requests across multiple web servers.

ATS is used by many high-traffic websites to improve responsiveness and reduce server load. It can be deployed in front of web servers like Apache and Nginx to substantially improve performance. Major technology companies like Facebook and Wikipedia use ATS to handle massive request volumes.
