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.
