Introduction
In the previous chapter, you learned about observability in serverless and how important it is to help you identify issues. Good observability will help you identify issues, but in order to prevent those issues from occurring in the first place we need to use chaos engineering.
In this chapter, you will be carrying out a manual chaos experiment where you inject an error into your serverless architecture and then introduce a mitigation. You will build a full continuous integration and continuous deployment pipeline in Azure DevOps, before building a continuous chaos pipeline in Azure DevOps, which will allow you to build a regression suite of automated chaos experiments to prevent weaknesses reappearing.
