How to Optimize Java Apps on Kubernetes

Java is an object-oriented language that’s been around since the 1990s. Originally designed to make application development easier, consistent upgrades through the years have kept Java up to date and increased its cross-platform capabilities. Consequently, Java is still a favorite for many developers, even in the modern world of containers and Kubernetes.

While Java is a favorite for many reasons, there are also significant challenges related to resource management, such as resource contention. Kubernetes solved part of the resource management problem by addressing the resource contention issues.

Before containers, we would deploy processes onto a machine and give them access to all its memory and CPU processing time. This meant that each process viewed the unused CPU time and memory as its own. It’s like having a bunch of children who all believe they own the playground. Conflicts would frequently occur whenever more than one process claimed more resources to remain operational.

Fast forward to today.

Kubernetes allows us to deploy containers to a machine and restrict the resources that the containers can see and use. You can think of it as subdividing a playroom with walls to ensure each child has access only to their own allocated play area. This allows Kubernetes to have greater control over resource use within a cluster. But key challenges remain in running Java apps efficiently on Kubernetes.

This article will delve into those issues and cover best practices for optimizing Java apps on Kubernetes.
