In this episode, I spoke with Heitor Lessa, who is a principal solution architect at AWS that specializes in serverless. He's also the man behind the popular AWS Lambda Powertools project which is available in a number of languages.

We talked about the history of the Lambda Powertools project, and the challenges and learnings from building in public. And Heitor shared the public roadmap for the Lambda Powertools and announced some exciting features that are going to be available soon.

Additionally, we also discussed the trade-offs of monolithic Lambda functions, aka "fat functions", and why Heitor prefers them nowadays. And we talked about Lambda Layers and when it's a good idea to use them. Hint: You shouldn't use Lambda Layers as a replacement for package managers such as NPM.

You can also watch this episode on YouTube here, and see the code samples that Heitor shared during the episode.
