The Cloud Cost Optimization Playbook: Stop Burning Money on AWS

Cloud bills have a way of sneaking up on you. What started as $500/month is now $15,000, and nobody can explain where it's going. We've audited dozens of AWS environments, and the pattern is always the same: oversized instances, forgotten resources, and zero visibility.

The 30-Day Audit

Start with AWS Cost Explorer. Tag everything. Identify the top 10 cost drivers. In our experience, 80% of waste comes from: oversized EC2 instances, idle RDS databases, unattached EBS volumes, and NAT Gateway data transfer.

Right-Size Aggressively

Most instances run at 10-20% CPU utilization. Drop them a size or two. Use Graviton (ARM) instances for 20% savings. Enable auto-scaling so you only pay for what you use, when you use it.

Reserved vs. Spot vs. On-Demand

Steady-state workloads? Reserved Instances or Savings Plans save 40-60%. Batch processing? Spot Instances save 70-90%. Only use On-Demand for unpredictable, short-lived workloads.

Architecture Changes That Pay for Themselves

Move to serverless where it makes sense. Lambda + API Gateway costs nothing at low traffic and scales infinitely. Use S3 Intelligent-Tiering for storage. Replace self-managed Kafka with managed services.

Set Up Alerts and Governance

Budget alerts at 50%, 80%, and 100%. Automated shutdown of dev environments outside business hours. Monthly cost review meetings. Make cloud cost a team responsibility, not just finance's problem.
