In a previous article I have shown how a Natural Ajax web application can be packaged and deployed in a Docker container. The logical next step to leverage this approach is running the application in a Kubernetes cluster. Why? The answer is scalability. In an application based on Natural Ajax, Natural and Adabas it is rarely the Natural and Adabas backend that forms the performance bottleneck. More often it is either the browser frontend or the web frontend application. A Kubernetes cluster allows adding and removing instances of the web frontend application as needed and makes that part of the application arbitrarily scalable.
