An updated and curated list of selected readings to illustrate High Scalability, High Availability, High Stability, High Performance, and High Intelligence Back-end Designs. Concepts are explained in the articles of notable engineers (Werner Vogels, James Hamilton, Martin Kleppmann, etc) and credible references (highscalability.com, infoq.com, official engineering blogs). Case studies are taken from battle-tested systems those are serving millions to billions of users (Netflix, Alibaba, Flipkart, LINE, Spotify, etc).
> Understand your problems: performance problem (slow for a single user) or scalability problem (fast for a single user but slow under heavy load) by reviewing [design principles](#principles). You can also check some [talks](#talks) of elite engineers from tech giants (Google, Facebook, Instagram, etc) to see how they build and scale their systems.
> Checking out some [interview notes](#interview) and [compeleted architectures](#architectures) to get a comprehensive view. Before designing Whatsapp or Twitter on whiteboard, you must understand thoroughly fundamental building blocks (IPC, OSI, TCP/IP, Gossip, etc). It is even better to take a course on Distributed Systems or Distributed Computing. Good luck!
