Cloud bills grow quietly: a forgotten test environment, an oversized database, storage nobody owns. FinOps is the practice of making cloud spend visible, owned and optimized by the teams that create it. The first month should focus on visibility and guardrails; bigger savings follow once everyone trusts the data.
Week 1: make spend visible
- Turn on detailed billing exports: AWS Cost and Usage Reports, Azure Cost Management exports, or Google Cloud Billing export to BigQuery.
- Agree a small, mandatory set of tags or labels: owner, environment, application and cost center.
- Report untagged spend as its own line, so it shrinks over time.
Week 2: add guardrails
- Create budgets per account, subscription or project, with alerts going to the owning team and not just finance.
- Turn on anomaly detection where it's available, such as AWS Cost Anomaly Detection, and send alerts to a channel someone watches.
- Use policy to require tags on new resources and to restrict regions or instance families you don't need.
Week 3: remove obvious waste
- Stop or schedule non-production environments outside working hours.
- Delete unattached disks, old snapshots and idle load balancers once ownership is confirmed.
- Rightsize compute and databases, using AWS Compute Optimizer, Azure Advisor or Google Cloud Recommender as a starting point and your own utilization data to confirm.
- Add storage lifecycle rules that move infrequently accessed data to cheaper tiers.
Week 4: plan commitments and ownership
Only once usage is visible and waste is trimmed should you buy commitments — AWS Savings Plans or Reserved Instances, Azure reservations and savings plans, or Google Cloud committed use discounts. Commit to the steady baseline you've observed, not to peaks.
- Set up showback so each team sees its own costs every week.
- Track unit costs that match how the business thinks, such as cost per customer or per thousand transactions.
- Review the biggest cost drivers each month with engineering and finance together.
