Organizations need to deploy their software quickly, leveraging highly scalable and always available capabilities to maintain zero downtime. As more applications are containerized and deployed, it becomes increasingly complex for any organization to manage these containers. Hence, scaling becomes an issue. This is where Kubernetes shines. With Kubernetes, you can easily automate, deploy, scale, and monitor your applications. If you’ve read any documentation about Kubernetes services and networking, you’ve probably come across the terms ClusterIP, NodePort, LoadBalancer, and Ingress. There seems to be a lot of confusion around these terms, and you must understand the difference before you start building your next Kubernetes-based application. This tutorial will explain the difference between these four Kubernetes service types, and how you should choose the best one for your application. Kubernetes networking and services are a complex topic. You need to understand the needs of your application in order to successfully deploy it on Kubernetes. This means understanding the type of service you want to provide, the size and location of your cluster, and what kind of traffic you expect your application to receive. There are four types of services that Kubernetes supports: ClusterIP, NodePort, LoadBalancer, and Ingress. Each has their own set of requirements to enable them for your application, so you must understand which one you need before deploying. For example, NodePort allows pods within the same node to communicate with each other without having an IP address assigned.
