1. Leaving Resources Running
Unused VMs, disks, and test environments running 24/7 = silent cost leak.
Stop, deallocate, or schedule shutdowns.
2. Overprovisioning
Using large VM sizes “just in case” wastes money.
Start small, monitor usage, then scale.
3. No Cost Visibility
If you don’t track it, you can’t control it.
Use Azure Cost Management for budgets and alerts.
4. Ignoring Storage Costs
Snapshots, backups, and logs grow silently over time.
Apply lifecycle policies and clean up regularly.
5. No Auto-Scaling
Fixed resources can’t adapt to real demand.
Enable auto-scale to match usage dynamically.
6. Paying Pay-As-You-Go for Everything
Long-running workloads on PAYG = expensive.
Use Reserved Instances or Savings Plans.
7. Unused Public IPs & Load Balancers
Even idle networking components can cost money.
Remove or consolidate unused resources.
8. Poor Tagging Strategy
No tags = no accountability or visibility.
Use tags for cost allocation and tracking.
9. Wrong Service Choice
Using IaaS where PaaS is enough increases cost and effort.
Choose the right service model for the workload.
10. Cross-Region Data Transfer
Moving data between regions adds hidden charges.
Keep workloads and data in the same region when possible.
Quick Win:
Tag resources + enable budgets + auto-shutdown = immediate cost control.
