Cost Management for Lambda
Explore various techniques and best practices for monitoring and optimizing the cost of your AWS Lambda usage, ensuring efficient resource consumption.
What Drives Lambda Costs?
Start by understanding the core principles of AWS Lambda's pricing. It's a true pay-per-use model, meaning you only pay for the compute time and resources your functions consume.
- You're charged for the number of requests to your functions.
- You're charged for the duration your code executes.
- Memory allocated significantly impacts both performance and cost.
Deconstructing Lambda Pricing
Lambda costs are primarily calculated based on two dimensions:
- Requests: The number of times your function is invoked. This is a flat rate per million requests.
- Duration: The time your code runs, measured from when it starts executing until it returns or otherwise terminates. This is rounded up to the nearest millisecond.
Duration cost is further influenced by the memory you allocate, measured in "GB-seconds".
