Cost Optimization in Serverless Architectures
Learn practical techniques to control and reduce the cost of serverless applications on AWS Lambda, from memory tuning to architecture choices.
Why Cost Matters in Serverless
Serverless removes idle-server costs, but it does not remove the need for cost awareness. You pay per request and per GB-second of compute.
Small inefficiencies multiply across millions of invocations, so understanding the pricing model is the first step to controlling spend.
The Lambda Pricing Model
AWS Lambda charges on two axes:
- Requests: a flat price per million invocations
- Duration: billed in GB-seconds (allocated memory multiplied by execution time)
Cutting either duration or allocated memory directly lowers the bill.
