For AWS Lambda Serverless invocations, what is the DDU cost calculation?

The correct answer involves understanding the pricing structure for AWS Lambda invocations, particularly how data transfer and invocations are charged. For AWS Lambda, the cost per invocation is a critical aspect of managing overall expenses when using serverless architecture.

In this case, $0.0000002 per invocation is the charge for Lambda invocations, but when calculating the cost for data transfer and how it pertains to the usage of Lambda functions—especially when considering DDU (Data Delivery Unit)—the cost can often be nuanced depending on the context of usage.

The identified answer reflects the appropriate interpretation of AWS pricing for Lambda functions and is likely based on a standardized cost structure for serverless environments where processing, usage patterns, and invocation randomness are taken into account. The selection illustrates an understanding of AWS Lambda pricing tiers that might involve tiers of data processing by the function, allowing for calculations at different levels based on execution time, data processed, and other metrics that come into play.

This highlights the importance of careful assessment when interpreting costs in the context of cloud services and serverless solutions, particularly in AWS where pricing models can vary significantly based on the specific functionalities and features being leveraged during integration or execution.
