Backend engineering is an art. During my 18 years career working with and building backend applications, I discovered certain communication design patterns keep emerging. There are only handful of ways clients communicate with backend applications, although they might be more, I believe the patterns I discuss in this course are the most common. Examples of these patterns are request-response, publish-subscribe, short and long and push.
Based on these communication design patterns, engineers may use a number of protocols for concrete communication. While the fundemental protocols boils down to either TCP or UDP, tons of industry specific protocols are built on top of these two to address certain problems. Examples of these high level protocols are HTTP/1.1, HTTP/2, HTTP/3, QUIC, gRPC, WebRTC and many more. Each protocol has its pros and cons and fits certain use cases. In the course, I discuss the top common protocols and provide examples and demos where applicable.
Once the request reaches the backend, the application has to execute the request. The backend has a buffet of design choices when it comes to the style of execution it can choose. Understanding the difference between a process and a thread, multi-process, multi-threaded and the correlation to the number of CPU cores or hardware threads is crucial to pick the right execution pattern. One does not have to stick with these patterns but can invent new ones that suits their needs.
This course is designed for engineers who have built backend applications, it is an intermediate — advance level course, certain programming and networking knowledge is required so I recommend taking my fundamentals of network engineering course before taking this course if you don’t have the networking skills. I hope you enjoy this course, and thank you so much for considering it.
