Summary

In this chapter, we explored the benefits of using Terraform for IaC and discussed the importance of incorporating CI/CD processes in Terraform workflows. We covered testing infrastructure and various tools for automating deployment.

In the final section, we explained how to deploy Atlantis, an open source tool for automated Terraform pull request previews, to AWS and configure GitHub to trigger terraform plan and terraform apply. With Atlantis, Terraform users can collaborate on infrastructure changes through GitHub pull requests, allowing for infrastructure changes to be reviewed and approved before they are applied to production. By incorporating Atlantis into your Terraform workflow, you can improve collaboration, reduce errors, and achieve faster and more secure infrastructure changes.

In the final chapter, we will slow down a little and talk about DevOps misconceptions and antipatterns, and how to avoid them.
