## What it is
Apache Traffic Control is an open-source implementation of a full Content Delivery Network, built around Apache Traffic Server as the caching layer, with components like Traffic Ops for management and monitoring via a RESTful API. The project has been retired to the Apache Attic and is no longer actively maintained.

## Use cases
- build your own cdn with open source software
- self-host a content delivery network
- cache content closer to users to reduce latency
- reduce origin server load and bandwidth costs
- manage and monitor a distributed cache fleet via api
- deliver large-scale content to geographically distributed users

## When to choose
- you need a fully self-hosted, open-source CDN and are comfortable maintaining retired software yourself
- you already run Apache Traffic Server and want its original control plane
- you want to study or fork a complete CDN implementation

## When to avoid
- you need an actively maintained project with security patches and community support
- you just need simple HTTP caching or a reverse proxy rather than a full CDN
- you want a managed or commercial CDN solution

## Facets
- artifact type: service
- maturity: abandoned
- function: caching, api-framework, monitoring, http-server
- domain: networking, infrastructure-as-code, self-hosted, microservices, web-development
- platform: go, self-hosted, cloud
- tags: cdn, content-delivery, traffic-server, cache-proxy, apache-attic, retired-project, linux, docker
