FinOps — How We Tamed Cloud Costs

FinOps — How We Tamed Cloud Costs

September, Azure invoice: 40% more than budget. Nobody knew what was costing so much. FinOps (Financial Operations) gave us a systematic approach to managing cloud expenses.

Step 1: Visibility — mandatory tagging

We implemented mandatory tags: project, environment, owner, cost-center. Azure Policy rejects resources without tags. Retroactive tagging of existing resources was painful — but the result is clear visibility in Azure Cost Management.

Step 2: Quick wins

  • Dev/test auto-shutdown outside working hours: -60% on dev
  • Right-sizing oversized VMs: -25%
  • Orphaned resources (unused disks, IPs): -5%
  • Reserved Instances for stable workloads: -40%

Step 3: Culture of responsibility

Every team sees costs in weekly reports. Rule: whoever creates a resource is responsible for it. Cost efficiency is also discussed in sprint reviews.

Total savings: 35% of monthly cloud costs, without performance loss.

Cloud without FinOps = blank check

FinOps isn’t about saving money — it’s about informed decisions. Invest in visibility and culture of responsibility.
