Hi everyone,

I’m currently learning networking fundamentals (OSI model, TCP/IP, HTTP/HTTPS, DNS, basic IP addressing) as part of my DevOps learning path.

Instead of general career advice, I’m trying to identify specific gaps in my understanding from a practical standpoint.

For example, I can understand the theory, but I’m not fully confident in applying it to real scenarios like:

• Debugging why a service is not reachable
• Understanding how DNS issues actually manifest
• Identifying whether a problem is at the application, transport, or network level

I’d appreciate insights on:

• Which practical networking concepts or skills are most commonly used in real-world environments?
• What kind of debugging or troubleshooting skills should I build early?
• Any specific tools or exercises that helped you move from theory to real understanding?

Thanks!

Hi everyone,

I’m currently pursuing a BSc in Computer Science and I’ve recently decided to focus on Cloud and DevOps.

So far, I’ve completed basic Linux (CLI, permissions, package management), and now I’m moving into networking. However, I’m feeling a bit overwhelmed because there’s a lot of scattered information online, and different people suggest different paths.

I’d really appreciate some guidance from those already working in this field:

• What should I focus on next after basic Linux?
• How deep should I go into networking for DevOps?
• Which resources (courses, docs, or practice methods) actually helped you?
• How can I avoid wasting time on unnecessary topics?

My goal is to build strong fundamentals and eventually become job-ready, not just follow tutorials blindly.

Any advice or roadmap suggestions would be really helpful. Thanks in advance!
