Thinking Serverless – Using AWS SAM CLI to Build and Test a Serverless App Locally (video tutorial)

Here’s a video from the Columbia AWS Meetup held on May 17, 2018 about how to use AWS Serverless Application Model (SAM) Command Line Interface (CLI) to build and test a serverless app locally.

In this presentation, Meetup member Neil Giarratana uses SAM CLI to build a sports score application.

Some of the things Neil presents include:

1. Best practices and anti-patterns for serverless application architecture
2. Leveraging SAM CLI to launch his API server, invoke Lambdas from the CLI, and generate payloads for different types of events
3. Consolidating your code repositories to better handle cross-dependencies in a distributed system
4. Using AWS X-Ray to more easily debug in a distributed system
5. Utilizing middleware for common tasks such as authorization, caching, validation, and more

Check out the video below and let us know your thoughts. Now go on and start building a serverless application!
