The second course in the DevOps on AWS series explains how to improve the deployment process with DevOps methodology, and also some tools that might make deployments easier, such as Infrastructure as Code, or IaC, and AWS CodeDeploy.

The course begins with reviewing topics covered in the first course of the DevOps on AWS series. You will learn about the differences between continuous integration, continuous delivery, and continuous deployment. In Exercises 1 and 2, you will set up AWS CodeDeploy and make revisions that will then be deployed. If you use AWS Lambda, you will explore ways to address additional considerations when you deploy updates to your Lambda functions. Lastly, you will end the week by discovering ways to troubleshoot deployment errors.

Next, you will explore how infrastructure as code (IaC) helps organizations achieve automation, and which AWS solutions provide a DevOps-focused way of creating and maintaining infrastructure. In Exercise 3, you will be provided with an AWS CloudFormation template that will set up backend services, such as AWS CodePipeline, AWS CodeCommit, AWS CodeDeploy, and AWS CodeBuild. You will then upload new revisions to the pipeline.

Note: This series is made up of three courses based on the steps of DevOps process. The first three steps "Code, Build, Test" are covered in the first course. The next two steps, "Release and Deploy" are covered in the second course. And then finally, our third course of the series covers the final steps "Operate and Monitor". We recommend taking all three DevOps on AWS courses in the prescribed order for a logical and thorough learning experience.
