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 explored topics surrounding how Kubernetes manages cluster resources and schedules our workloads. With concepts such as Quality of Services, priority, and node out of resource handling in mind, we can optimize our resource utilization while keeping our workloads stable. Meanwhile, ResourceQuota and LimitRange add additional layers of shields to running workloads in a multi-tenant but sharing resources environment. With all of this protection we've built, we can confidently count on Kubernetes to scale our workloads with autoscalers and maximize resource utilization to the limit.

In Chapter 9, Continuous Delivery, we're moving on and setting up a pipeline to deliver our product continuously in Kubernetes.
