Overview of this book

Kubernetes has been widely adopted across public clouds and on-premise data centers. As we're living in an era of microservices, knowing how to use and manage Kubernetes is an essential skill for everyone in the IT industry. This book is a guide to everything you need to know about Kubernetes—from simply deploying a container to administrating Kubernetes clusters wisely. You'll learn about DevOps fundamentals, as well as deploying a monolithic application as microservices and using Kubernetes to orchestrate them. You will then gain an insight into the Kubernetes network, extensions, authentication and authorization. With the DevOps spirit in mind, you'll learn how to allocate resources to your application and prepare to scale them efficiently. Knowing the status and activity of the application and clusters is crucial, so we’ll learn about monitoring and logging in Kubernetes. Having an improved ability to observe your services means that you will be able to build a continuous delivery pipeline with confidence. At the end of the book, you'll learn how to run managed Kubernetes services on three top cloud providers: Google Cloud Platform, Amazon Web Services, and Microsoft Azure.

Summary

In this chapter, we discussed the public cloud. AWS is the most popular public cloud service and it gives APIs the ability to control AWS infrastructure programmatically.

In addition, AWS EKS makes it easy to deploy Kubernetes on AWS. Furthermore, the control plane manages the master and etcd with high availability design that offloads huge management efforts.

On the other hand, you need to be aware of AWS basics such as availability zone awareness between pod (EC2) and persistent volume (EBS). In addition, you need intermediate AWS knowledge such as IAM credentials to gain access to an API server and use a worker node Instance Role ARN to register the cluster.

In addition, using ALB as ingress controller is available as of December 2018 (https://aws.amazon.com/blogs/opensource/kubernetes-ingress-aws-alb-ingress-controller/), but it also requires additional effort to configure...
