Nginx 101

The nginx web server was mainly created to solve the C10k problem (problems that arise when serving a large no. of clients at the same time). So, as a web server, it can serve your data with blazing speeds. But nginx is much more than just a web server and following are some of those that it is good at:

• Reverse proxying — Easy integration with slower upstream servers (like Unicorn or Puma).
• load balancing — Distribute your traffic properly, stream media, resize your images on the fly, cache content, and much more.
