Most modern applications are now built using containers, microservices with their dependencies and configurations. Kubernetes—usually abbreviated as K8s—is an open-source platform developed by Google that allows users to construct, deliver, and run those containers at scale in ways that improve availability and scalability.

People usually confuse choosing between Docker and Kubernetes. This is a common misconception because Docker is a containerization tool. In contrast, Kubernetes is a platform for orchestrating multiple Docker clusters. However, Docker frequently benefits from using Kubernetes, and the same goes another way. This article will explain the advantages of using Kubernetes, when to use it, and when not to use it.

Benefits of Using Kubernetes

Kubernetes works by grouping a bunch of pods that perform related functions that communicate with each other through APIs located in the master node.

Kubernetes allows workloads exist in a single cloud so they can be spread easily across multiple cloud services. Moreover, Kubernetes helps you run your containerized apps reliably by automatically placing and balancing the workloads, scales clusters appropriately based on the demand, and provides no downtime.

While Kubernetes has some more exceptional benefits, it is unnecessary to use it in every application. You're gonna see when to and not to use it.

When to Use Kubernetes

If you're thinking of moving your app to the cloud without messing with any cloud stuff, working on-premise on top of containers with the help of Kubernetes may be your best choice.

Your application may also reach a point where it needs to scale. In this case, it is also a great choice to use Kubernetes.

When not to Use Kubernetes

Suppose you're a developer and just start building a personal project. In that case, I'm sure you don't want to dive into the complexities of Kubernetes.

Kubernetes is a complex platform, and transitioning to Kubernetes is no easy task. Kubernetes requires significant expertise for effective management and maintenance. A company needs to really understand the problem they're solving before choosing to use it. If you think managing a Kubernetes cluster is too much for your application, you may want to take a step back.

Final Thoughts

Now that you reach the end of this article, I'm sure you've understood Kubernetes' advantages, when to use it, and when not. In conclusion, don't use Kubernetes just for the hype. Use it only if it is the best solution for your application.
