Udemy Fundamentals Of Backend Engineering Link

Why creating new database or downstream connections for every request destroys performance, and how reusing a pool of pre-warmed connections fixes it. Why Choose This Course Over Other Tutorials? Focus on First Principles

: Understand how the Operating System interacts with your application through threads, processes, and non-blocking I/O.

A deep dive into Layer 4 (TCP and UDP) versus Layer 7 (Application protocols). You will learn the mechanics of the TCP 3-way handshake and why UDP is preferred for low-latency streaming. udemy fundamentals of backend engineering

"Fundamentals of Backend Engineering" takes the opposite approach. It focuses entirely on fundamental principles. By understanding the underlying mechanics of networking, protocols, and operating systems, you gain the ability to learn any new backend framework or language in a fraction of the time. You stop being a "Node.js developer" or a "Python developer" and become a true backend architect. Key Modules and What You Will Learn

Easy to develop, test, and deploy initially. Low latency since all functions run in the same memory space. Why creating new database or downstream connections for

Detailed breakdowns of HTTP/1.1, HTTP/2, and the newer HTTP/3 protocol built on QUIC. It also explores gRPC, WebSockets for bi-directional communication, and WebRTC.

: Software engineers who have already built basic backends but want to understand what happens "under the hood". A deep dive into Layer 4 (TCP and

You learn how to make systems faster by understanding networking overhead. Conclusion

: Understanding how the OS Kernel communicates with apps, including threads, processes, and asynchronous I/O in Linux.

Prioritize horizontal scalability and flexible schemas, often adhering to the CAP theorem (balancing Consistency, Availability, and Partition Tolerance). Storage Engines: Indexes and Logs
