Intro

Automated, Continuous Build and Continuous Delivery are must-haves when building modern applications on AWS. To achieve this, you have numerous options, including third party providers like GitHub Actions and Circle CI, and the AWS services, CodePipeline and CodeBuild. In this episode we focus on GitHub Actions and we compare it with the native AWS features offered by services like CodePipeline and Code Build. In particular we discuss what CodePipeline offers and how to set it up, what the tradeoffs are and when to choose one over the other. We also discuss when you should look outside AWS to a third-party provider and highlight when GitHub Actions can be a great fit for your AWS CI/CD needs!

In this episode, we mentioned the following resources:

- Example pipeline for a serverless mono repo using CDK is available in SLIC Starter: https://github.com/fourTheorem/slic-starter/tree/main/packages/cicd
