<?php // Example of optimizing AWS Lambda function function optimizedLambdaFunction($event, $context) { // Perform necessary operations $result = heavyCalculation($event['input']); return $result; } function heavyCalculation($input) { // Optimize the code for execution time return $input * 2; // Simple operation for demonstration } ?>

Main Cost Drivers for AWS Lambda

  • Invocation Count: Number of times your Lambda function is called.
  • Execution Duration: Total time your function runs, measured in milliseconds.
  • Memory Allocation: Amount of memory (from 128 MB to 10 GB) assigned to your function.
  • Data Transfer: Costs associated with data transferred in and out of AWS services.

Optimization Strategies

  1. Optimize Function Code: Streamline your code to reduce execution time.
  2. Batch Processing: Group requests to reduce the number of invocations.
  3. Memory Allocation: Adjust the memory setting to find the sweet spot between performance and cost.
  4. Utilize AWS Free Tier: Take advantage of AWS Free Tier for initial development and testing.
