Vietnamese organizations new to Azure typically overshoot budget by 30-50% in the first six months — not because they over-provision, but because pay-as-you-go pricing runs 40-72% higher than commitment-based options. FinOps isn't workload-cutting, it's cost-structure optimization.
Four levers, ordered by ROI
- 1-year Reserved Instances (RI) for stable VMs — 40-55% off
- 3-year Savings Plans for region-flexible compute — 60-72% off
- Auto-shutdown for dev/test VMs outside working hours — 65% of runtime saved
- Rightsizing: identify VMs under 20% CPU and downgrade — 30-50% saved on those VMs
The most common mistake
Vietnamese companies often buy 3-year RIs for every VM right after migration — that's a mistake. New workloads aren't stable in months 0-6; locking in early traps you with the wrong SKU. Recommendation: run pay-as-you-go for three months, mine the Cost Management reports for steady-state workload, then buy RIs for the baseline.
Reports and alerts to set up
- Budget alerts at 80% and 100% — routed to the IT lead and CFO
- Daily anomaly detection — Azure flags unusual spend spikes automatically
- Tag every resource by cost center (project, department, environment)
- Monthly executive report sliced by tag
Digi43 runs FinOps assessments for Azure — 30-day usage analysis, RI/Savings Plan mix proposal, and Cost Management report wiring. Typical result: 25-40% saved within the first billing cycle.
