The pricing for AWS Lambda is determined by several factors, including the number of requests, duration, and memory allocation. AWS also offers a free tier for Lambda, which allows users to run functions for free up to a certain limit.

• Number of Requests: The cost of AWS Lambda depends on the total number of requests executed by your functions.
  ‍
• Duration: The cost is also affected by the duration of function execution, measured in milliseconds. Longer-running functions will incur higher costs.
  ‍
• Memory Allocation: The cost of AWS Lambda is influenced by the amount of memory allocated to your functions, which in turn determines CPU power, network bandwidth, and disk I/O.

AWS Lambda offers both free and paid usage options. Users can take advantage of the AWS Lambda free tier, which provides a generous allowance of requests and execution time each month. Beyond the free tier limits, users will be billed according to the pay-as-you-go pricing model.
