This post expands on the functionality introduced with the PowerShell custom runtime for AWS Lambda. The previous blog explains how the custom runtime approach makes it easier to run Lambda functions written in PowerShell. You can add additional functionality to your PowerShell serverless applications by importing PowerShell modules, which are shareable packages of code. Build your own […]

Cost optimization is an important part of creating well-architected solutions and this is no different when using serverless. This blog series explores some best practice techniques to help reduce your Lambda bill.

This blog post explains how Lambda pricing works and how right-sizing applications and tuning them for performance efficiency offers a more cost-efficient utilization model. The results can also reduce latency, creating a better experience for your end users.
