Understanding how the OS kernel manages sockets , file descriptors , and TCP/IP stacks to communicate with your code. udemy fundamentals of backend engineering
: Choosing between connection-oriented, reliable delivery and connectionless, high-speed streaming.
How does a server handle 10,000 concurrent requests? The course demystifies web server internals by looking at: navigating the complex world of servers
Students can learn at their own pace, re-watching lectures on complex topics like concurrency or database locking when needed. Conclusion: Starting Your Journey
While frontend development creates the "look," backend engineering provides the "logic." For aspiring developers seeking to transition from writing code to engineering scalable systems, navigating the complex world of servers, databases, and APIs can be daunting. approach, often centered around comprehensive courses like Database Essentials for Backend Engineers , provides a structured path to mastery, tackling both the foundational concepts and the practical skills required in the industry. and APIs can be daunting. approach
Implementing JWT (JSON Web Tokens) or OAuth2 ensures secure stateless authentication. Backend engineers must also defend against classic vulnerabilities like SQL Injection (using parameterized queries) and Cross-Site Scripting (XSS).
: Understanding Request-Response, Publish-Subscribe, Short/Long Polling, and WebSockets.
The course covers a range of topics, including:
noted that the course goes beyond theory, enhancing practical skills: "This course has significantly enhanced my skills in developing reliable backend services by understanding what happens in the backend therefore it is easier to know when and where to optimize your backend service." He highlighted the depth of topics like how the kernel creates a socket and how the backend process reads and writes to it as "fascinating" and "outstanding".
