When writing this chapter, we were hoping to close the loops around a production-grade AWS CDK setup. In this chapter, we learned how to purchase domains in Route 53 and create hosted zones for them. We then went on a (necessary) wild goose chase validating a DNS to issue ACM certificates. We then realized how CDK saves us time by doing most of the work of DNS validation for us. We configured an RDS MySQL database for our TODO application, and we also learned about the importance of storing secrets safely and how to do that with CDK apps.
There are six more chapters in this book. That said, if you’ve gotten this far, you have the general knowledge to start creating awesome DevOps automations with AWS CDK. We hope the game-changing characteristics of CDK are becoming as evident to you as they are to us. In the next chapter, we will cover how to build bulletproof CI/CD pipelines for CDK applications. See you there!
