leandromoreira/CDN-up-and-running: CDN Up and Running - Building a CDN from Scratch to Learn

  • CDN Up and Running
  • This repo aims to build a body of knowledge on how CDNs work by coding one from "scratch". The CDN we will design uses: Nginx, Lua, docker, docker-compose, Prometheus, grafana, and wrk.
  • We'll start creating a single backend service and expand to a multi-node, latency-simulated, observable, and testable CDN. In each section, there are discussions regarding the challenges and trade-offs of building/managing/operating a CDN
