| Fact | Apache Traffic Server | Varnish Cache |
|---|---|---|
| Purpose | Apache Traffic Server is a fast, scalable, extensible HTTP/1.1 and HTTP/2 caching proxy server. | Varnish Cache is a reverse caching proxy that serves cached responses from memory and proxies other requests to origin servers. |
| Security | Security options include client access controls, client authentication, SSL termination, and access control via SSL. | The security guide describes four control levels: command-line arguments, the CLI interface, VCL programs, and HTTP requests. |
Traffic Server suits organizations such as enterprises, internet service providers, backbone providers, and large intranets that need a caching proxy or reverse proxy. Its plugin APIs may also suit teams that need custom HTTP or cache behavior.
Varnish Cache suits Linux users who want to host a reverse caching proxy themselves and configure caching behavior in VCL. It may fit teams that need container or Kubernetes deployment options and operational logs and metrics.
