Overview of this book

With its broad adoption across various industries, Kubernetes is helping engineers with the orchestration and automation of container deployments on a large scale, making it the leading container orchestration system and the most popular choice for running containerized applications. This Kubernetes book starts with an introduction to Kubernetes and containerization, covering the setup of your local development environment and the roles of the most important Kubernetes components. Along with covering the core concepts necessary to make the most of your infrastructure, this book will also help you get acquainted with the fundamentals of Kubernetes. As you advance, you'll learn how to manage Kubernetes clusters on cloud platforms, such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP), and develop and deploy real-world applications in Kubernetes using practical examples. Additionally, you'll get to grips with managing microservices along with best practices. By the end of this book, you'll be equipped with battle-tested knowledge of advanced Kubernetes topics, such as scheduling of Pods and managing incoming traffic to the cluster, and be ready to work with Kubernetes on cloud platforms.

The LoadBalancer service

LoadBalancer services are a very interesting service to explain because this service relies on the cloud platform where the Kubernetes cluster is provisioned. For it to work, it is thus required to use Kubernetes on a cloud platform that supports the LoadBalancer service type.

Explaining the LoadBalancer services

Not all cloud providers support the LoadBalancer service type, but we can name a few that do support it, as follows:

  • AWS
  • GCP
  • Azure
  • OpenStack

The list is not exhaustive, but it's good to know that all three major public cloud providers are supported.

If your cloud provider is supported, keep in mind that the load-balancing logic will be the one implemented by the cloud provider: you cannot control how the traffic will be routed to your Pods from Kubernetes; you will have to know how the load-balancer component of your cloud provider works. Consider it as a third-party component implemented as a Kubernetes kind...
