FinOps for startups: how to cut your cloud bill by 40% without sacrificing reliability

Your Cloud Bill Is 40% Higher Than It Should Be—Here's Why You're probably overpaying for compute. Most startups are. Not because they're wasteful, but because they're not optimizing three critical levers: instance sizing, purchasing models, and workload placement. The good news? Fixing this takes a weekend, not a quarter. Right-Sizing: Your Biggest Quick Win Most teams provision for peak load, then never revisit. That t3.xlarge running at 12% CPU for months? Easy 30% savings by downsizing to t3.medium. Pull your CloudWatch metrics for the last 90 days—look at p95 CPU and memory, not average. Use that as your baseline, add 20% headroom, and resize. # Quick check: find underutilized instances aws ec2 describe-instances --region us-east-1 \ --query 'Reservations[*].Instances[*].[InstanceId,InstanceType,State.Name]' \ --output table Reserved Instances + Spot: The 1-2 Punch Baseline workloads (databases, always-on services)? Buy 1-year Reserved Instances—that's 40–50% off on-demand pricing
