AWS Cost Optimization with FinOps Practices
Written by Facto IT Engineering TeamPublished 10 February 2026
Question
How do we reduce AWS spend without breaking reliability?
Answer
Start with visibility and account guardrails, then rightsizing and scheduling non-production. Cost work sticks when architecture and FinOps ownership are clear — not when teams only delete idle instances once.
Visibility first
Tagging, budgets, and dashboards show which teams and environments drive spend. Without ownership, optimization becomes a one-off cleanup.
Architecture levers
Landing zones, IAM guardrails, and infrastructure as code prevent accidental sprawl. Rightsizing and scale-down schedules cut waste in non-production.
Sustain the gains
Review spend with engineering regularly. Pair FinOps metrics with reliability signals so cost cuts do not silently erode resilience.
