Common Cloud Learning Mistakes
Only watching tutorials
Cloud is hands-on. Without building projects, you won't retain knowledge. Use the free tier to practice.
Skipping Linux fundamentals
Most cloud servers run Linux. Without Linux basics, you'll struggle with real cloud work.
Ignoring networking
VPCs, subnets, security groups—networking is foundational. Don't skip it even if it seems boring.
Forgetting about cost
Always clean up resources after practice. Set billing alerts. Unexpected bills happen.
Learning too many clouds at once
Master one cloud first (preferably AWS). Concepts transfer. Learning 3 clouds at once leads to confusion.
