In simple English
This program acts as a middleman between website visitors and your web servers. It sits in front of your applications and saves copies of web pages in its memory or disk. When a new person visits, it serves the saved copy instantly without waking up your main application. It requires a dedicated server, advanced Linux knowledge and ongoing maintenance to keep it running smoothly. It costs nothing in licence fees because it is free open-source software.
What it is
Apache Traffic Server is a high-performance reverse proxy and caching server written in C++. It handles massive web traffic loads by caching content and routing requests efficiently across multiple backend nodes.
What it is good for
Solo builders and infrastructure engineers who run high-traffic web applications and need to reduce server load by caching static or dynamic responses close to the user.
- Handles millions of concurrent requests with low memory and CPU overhead.
- Supports modern protocols including HTTP/2, HTTP/3, and QUIC.
- Extensible through a robust plugin API written in C and C++ or Lua.
- Requires compiling from source code using CMake and a C++17 compiler, which is difficult for non-programmers.
- Demands careful tuning of memory, file descriptors, and kernel settings to perform well.
- Complex configuration files can take significant time to master.
