Hands-On Kubernetes on Azure

By: Shivakumar Gopalakrishnan, Gunther Lenz

Overview of this book

Microsoft is now one of the most significant contributors to Kubernetes open source projects. Kubernetes helps to create, configure, and manage a cluster of virtual machines that are preconfigured to run containerized applications. This book will be your guide to performing successful container orchestration and deployment of Kubernetes clusters on Azure. You will get started by learning how to deploy and manage highly scalable applications, along with understanding how to set up a production-ready Kubernetes cluster on Azure. As you advance, you will learn how to reduce the complexity and operational overheads of managing a Kubernetes cluster on Azure. By the end of this book, you will not only be capable of deploying and managing Kubernetes clusters on Azure with ease, but also have the knowledge of best practices for working with advanced AKS concepts for complex systems.

Using Deployments makes upgrading a straightforward operation. As with any upgrade, you should have good backups in case something goes wrong. Most of the issues you will run into will happen during upgrades. Cloud-native applications are supposed to make dealing with this relatively easier which is possible only if you have a very strong development team that has the ability to do incremental rollouts (with support for rollback).

There is a trade-off between getting features out for customers to see versus spending a lot of time ensuring developer training, automated tests, and disciplined developers and product managers. Remember, most successful companies that do upgrades in production multiple times a day had for years monolithic applications that generated revenue before they were able to switch to a microservices-based approach.
