#DevOps Diaries #130
If I had to recommend ONE single AWS service you should learn first… my answer is always IAM.
Without proper IAM, nothing else in AWS really matters.
I was recently talking to a friend who strongly argued for VPC first. His point was is okay as VPC is important.
But here’s the reality:
You can build and run services without a custom VPC( lots of managed services ).
But without IAM? You’re completely stuck. You can’t create resources, you can’t assign permissions, you can’t secure anything, and every single service becomes useless.
IAM is the foundation of AWS security and access control. Everything else sits on top of it.
So my strong advice:
Don’t just “learn” IAM ==> Be a Master in IAM
Understand:
- Users, Groups, Roles & Policies
- IAM Identity Center (SSO)
- IAM Access Analyzer
- Least Privilege principle
- Policy evaluation logic
- Resource-based vs Identity-based policies
Trust me : the time you invest in mastering IAM will save you hundreds of hours of debugging weird permission errors later.
