Nasser explains that while core transport vehicles are limited to either TCP or UDP, "tons of industry-specific protocols are built on top of these two to address certain problems and use cases". Understanding these relationships helps you choose the right protocol for the right job.
Understand how forward proxies protect clients (like a VPN), while reverse proxies (like Nginx or HAProxy) protect servers.
You will move away from localhost and into the cloud.
Understanding execution patterns is crucial for picking the right pattern for your use case. Nasser emphasizes that you don’t have to stick with existing patterns—you can invent new ones that suit your specific needs. udemy fundamentals of backend engineering exclusive
Understanding the evolution of speed and security.
How to handle data updates before WebSockets were mainstream.
Google’s high-performance RPC (Remote Procedure Call) framework that leverages HTTP/2 and Protocol Buffers for lightning-fast microservice communication. 2. Backend Architectural Styles Nasser explains that while core transport vehicles are
If you’re brand new to programming, hold off. Build some applications first, learn a language, create a few basic APIs. Then come back to this course when you’re ready to understand what you’ve been building on a deeper level.
Here is a mini-roadmap for 2026:
Cyclically routes requests down the list of servers. You will move away from localhost and into the cloud
By understanding the underlying network protocols, database engines, and operating system behaviors, you gain the skills to debug complex system failures and architect applications that can handle millions of concurrent users. Pillar 1: Communication Protocols and Patterns
This is not a beginner’s course. The course description makes that clear: Fundamentals of Backend Engineering is designed for engineers who have already built backend applications. It’s an intermediate-to-advanced level program that assumes you have some practical experience under your belt.
You will not get a certificate just for watching videos. The final project is an .
