Networking

Learning computer networking is essential for DevOps and Site Reliability Engineering (SRE). Understanding how data flows between systems, how DNS works, how HTTP requests are routed, and how network protocols interact will help you troubleshoot production issues, design reliable infrastructure, and perform well in technical interviews.

Instead of searching through scattered blogs and videos, this page brings together the most valuable networking resources specifically for DevOps and SRE engineers.
