These are the same Lambda functions we all love, but they let you run multi-step workflows by keeping checkpoints and state. What does this mean? You can run similar functionality to what we’ve typically used AWS Step Functions for. But instead of using Amazon State Language, you can use familiar code and dependencies.

The Lambda Powertools team released a new feature that allows your Lambda functions to buffer logs. That sounded cool, but I didn’t understand how it would work or how logs would show in CloudWatch. I decided to try it out and provide a visual example of how it looks with different configuration options.

I’ve seen a lot of posts around the problems that Lambda Layers bring. A very good one is called You shouldn’t use Lambda Layers by AJ Stuyvenberg. In this post AJ explains the myths and cons of using Lambda Layers. What is not easy to find is examples on how to actually get rid of Lambda Layers by using a bundler. In this post we will go through a structure and configuration that allows us to remove Layers by using ESBuild to bundle the dependencies and shared code for our…

A common way people build serverless APIs is by routing an API Gateway request to an AWS Lambda. This will make another request to a different AWS Service. It often goes unnoticed that API Gateway can integrate with other AWS Services without the need of Lambda.
