Serverless Stack — CI/CD — Blue-Green Deployments

About me

Full-stack software architect & entrepreneur

The problem I wanted to solve

I wanted to build a reusable serverless architecture with CI/CD and blue-green deployments.

What is Serverless Stack — CI/CD — Blue-Green Deployments?

The stack consists of an API, UI, and Async Tasks, but this isn’t the cool part.

The cool part is the built-in CI/CD via CodePipeline and Blue-Green deployments of Lambda.

CI/CD and Blue-Green deployments are very important for the stability and health of an application. It is important to deliver often and fail fast.

Tech stack

I used CloudFormation to design the architecture and stack.

I used CodeBuild and CodePipeline to perform CI/CD.

The API is powered by API Gateway and Lambdas.

The UI is a static S3 website.

The Async Tasks is powered by SNS and Lambda.

The blue-green deployments are performed by AWS CodeDeploy.

Here is the AWS Pipeline:

The process of building Serverless Stack — CI/CD — Blue-Green Deployments

With this reusable stack the setup is easy. Just fork my git branch and create the pipeline stack. All subsequent changes to your code or infrastructure are automatically deployed.

Challenges I faced

CloudFormation is always time consuming but worth every minute in the end.

Key learnings

I learned how to perform blue-green deployments or AWS Lambdas.
