1. Cloud Will Automatically Save Money
Costs increase quickly without design and control.
Optimize architecture, not just pricing.
2. Treating Azure Like On-Prem
Lifting and shifting VMs without redesign = poor performance + high cost.
Use PaaS and cloud-native patterns.
3. Ignoring Identity Design
Users, apps, and services need structured access control.
Design RBAC, groups, and managed identities from day one.
4. No Network Planning
IP overlap, DNS issues, and broken connectivity happen later.
Define hub-spoke, IP ranges, and DNS early.
5. Skipping Governance
No naming, no tagging, no policy = no control.
Implement landing zones, policies, and standards.
6. Thinking Security is “Handled by Azure”
Cloud is shared responsibility.
You are still responsible for data, access, and configuration.
7. No Cost Monitoring
Bills become a surprise at the end of the month.
Use Azure Cost Management with budgets and alerts.
8. Overengineering Early
Too many services, too complex design.
Start simple, scale when needed.
9. No Backup / DR Strategy
Assuming cloud = safe is risky.
Define backup, retention, and recovery processes.
10. Ignoring Operations
Deployment is easy, operations are not.
Plan monitoring, patching, and incident response.
Reality:
Most Azure problems are not technical — they come from wrong assumptions and missing fundamentals.
