Which factors determine the cost of AWS Lambda?

The cost of AWS Lambda is primarily determined by the number of requests that your functions receive and the duration that your code runs. Each time a request is made to a Lambda function, it counts as a "request," and AWS provides a free tier that includes a certain number of requests per month. After exceeding that limit, you incur charges based on the number of requests.

In addition to requests, the duration is a critical factor. Duration is calculated from the time your code begins executing until it returns or otherwise terminates, rounded up to the nearest 1 millisecond. The duration of your function directly impacts how much you pay, as you are billed based on the compute time reflected in the duration of execution.

Furthermore, memory size plays a role in the pricing structure. AWS Lambda allows you to configure the amount of memory allocated to your function, which can influence the computed resource's performance and execution time. While memory size does not directly contribute to cost in a straightforward manner like requests and duration, it affects how your function runs, potentially leading to variations in execution time and overall costs.

In summary, the combination of the number of requests, execution duration, and the allocated memory size when deploying an AWS Lambda function are the key factors that determine the cost
