Hands-On Kubernetes on Azure - Second Edition

Overview of this book

From managing versioning efficiently to improving security and portability, technologies such as Kubernetes and Docker have greatly helped cloud deployments and application development. Starting with an introduction to Docker, Kubernetes, and Azure Kubernetes Service (AKS), this book will guide you through deploying an AKS cluster in different ways. You’ll then explore the Azure portal by deploying a sample guestbook application on AKS and installing complex Kubernetes apps using Helm. With the help of real-world examples, you'll also get to grips with scaling your application and cluster. As you advance, you'll understand how to overcome common challenges in AKS and secure your application with HTTPS and Azure AD (Active Directory). Finally, you’ll explore serverless functions such as HTTP triggered Azure functions and queue triggered functions. By the end of this Kubernetes book, you’ll be well-versed with the fundamentals of Azure Kubernetes Service and be able to deploy containerized workloads on Microsoft Azure with minimal management overhead.

The software evolution that brought us here

There are two major software development evolutions that enabled the popularity of Docker and Kubernetes. One is the adoption of a microservices architectural style. Microservices allow an application to be built from a collection of small services that each serve a specific function. The other evolution that enabled Docker and Kubernetes is DevOps. DevOps is a set of cultural practices that allows people, processes, and tools to build and release software faster, more frequently, and more reliably.

Although you can use both Docker and Kubernetes without using either microservices or DevOps, the technologies are most widely adopted for deploying microservices using DevOps methodologies.

In this section, we'll discuss both evolutions, starting with microservices.

Microservices

Software development has drastically evolved over time. Initially, software was developed and run on a single system, typically a mainframe. A client...
