Cloud Computing has changed the way applications are being developed and how services are being operated. The a9s Data Services team has always been part of this change by leveraging popular open-source data services and making them consumable on modern Application Developer Platforms, commonly known as Platform-as-a-Service (PaaS).

In this article, we take finalizers a step further by performing the resulting actions of a resource deletion with the help of a custom controller.
