AWS CDK in Practice

By: Mark Avdi, Leo Lam

Overview of this book

As cloud applications are becoming more complex, multiple tools and services have emerged to cater to the challenges of running reliable solutions. Although infrastructure as code, containers, and orchestration tools, such as Kubernetes, have proved to be efficient in solving these challenges, AWS CDK represents a paradigm shift in building easily developed, extended, and maintained applications. With AWS CDK in Practice, you’ll start by setting up basic day-to-day infrastructure while understanding the new prospects that CDK offers. You’ll learn how to set up pipelines for building CDK applications on the cloud that are long-lasting, agile, and maintainable. You’ll also gain practical knowledge of container-based and serverless application development. Furthermore, you’ll discover how to leverage AWS CDK to build cloud solutions using code instead of configuration files. Finally, you’ll explore current community best practices for solving production issues when dealing with CDK applications. By the end of this book, you’ll have practical knowledge of CDK, and you’ll be able to leverage the power of AWS with code that is simple to write and maintain using AWS CDK.

MySQL powered by AWS RDS

In this chapter, as well as teaching you about Route 53, DNS, and certificates, we’ve also changed our main database to MySQL hosted on AWS’s Relational Database Service (RDS).

Let’s assume that you currently run a website with a MySQL database, and this book has inspired you to move to AWS and write your infrastructure code with AWS CDK. At some point, you are going to have to do a database migration. There are plenty of ways to do this with AWS, with the most complete solution being with AWS Database Migration Service.

Keeping with the theme of simplicity and giving you the tools to tackle infrastructure problems with AWS CDK, let’s go with the simplest scenario, which would essentially be an exported .sql from your current database. That said, our plan is pretty evolved and advanced and should cover most types of database migrations.

If you look in the infrastructure/lib/constructs/RDS/init directory, you will see one...
