In a three-article series published recently on this site (Part 1, Part 2, Part 3), I've been demonstrating the power of the AWS Cloud Development Kit (CDK) in the Infrastructure as Code (IaC) area, especially when coupled with the ubiquitous Java and its supersonic/subatomic cloud-native stack: Quarkus.

While focusing on the CDK fundamentals in Java, like Stack and Construct, together with their Quarkus implementations, this series was a bit frugal as far as the infrastructure elements were concerned. Indeed, for the sake of clarity and simplification, the infrastructure used to illustrate how to use the CDK with Java and Quarkus was inherently consensual. Hence, the idea for a new series, of which this article is the first, is a series less concerned with CDK internals and more dedicated to the infrastructure itself.
