How I Reduced AWS Costs by 66% Using CDK and Right-Sizing

Cloud costs can spiral out of control without proper governance. Here's how I cut AWS spending by 66% at receeve through systematic optimization.

Step 1: Audit Your Infrastructure

Before optimizing, you need visibility. Enable AWS Cost Explorer and tag every resource.

Step 2: Lambda Concurrency Tuning

Over-provisioned Lambda concurrency is a silent budget killer.

Step 3: DynamoDB Capacity Mode

Switch from Provisioned to On-Demand for workloads with unpredictable traffic patterns.

Step 4: CDK for IaC

Infrastructure as Code with AWS CDK gives you repeatability and the ability to destroy/recreate environments cleanly.

The result: 66% cost reduction within 3 months.
