Preface

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 you to monitor applications and cluster services to achieve high availability and dynamic scalability, to deploy web applications securely in Microsoft Azure with Docker containers. You will enhance your knowledge about Microsoft Azure Kubernetes Service and will learn advanced techniques such as solution orchestration, secret management, best practices, and configuration management for complex software deployments.

What this book covers

Chapter 1, Introduction to Docker and Kubernetes, covers the concepts of Docker and Kubernetes, providing the foundational context for the following chapters, where you will dive into how to deploy Dockerized applications in Microsoft AKS.

Chapter 2, Kubernetes on Azure (AKS), is a step-by-step instructional chapter on how to navigate the Azure portal to perform all the functions required to launch an AKS cluster, and also use Azure Cloud Shell without installing anything on your computer.

Chapter 3, Application Deployment on AKS, looks at the details of deploying an application on AKS, thereby teaching you about the usefulness of various Kubernetes concepts, such as pods, replication controllers, services, config maps, namespaces, and deployments.

Chapter 4, Scaling Your Application to Thousands of Deployments, shows how to scale deployments with Kubernetes by not only showing how to create multiple instances of the software, but also how to debug problems that you might run into.

Chapter 5, Single Sign-On with Azure AD, covers how to secure applications on an enterprise scale. By integrating applications with Azure Active Directory, readers can enable any application to link to an organization's Active Directory.

Chapter 6, Monitoring the AKS Cluster and the Application, will enable you to set alerts on any metric that you would like to be notified of by leveraging Azure Insights.

Chapter 7, Operation and Maintenance of AKS Applications, covers how to secure your AKS cluster with role-based security by leveraging Azure Active Directory as the authentication provider.

Chapter 8, Connecting an App to an Azure Database - Authorization, focuses on working with the WordPress sample solution, which leverages a MySQL database as a data store.

Chapter 9, Connecting to Other Azure Services (Event Hubs), covers how to implement microservices on AKS, including how to use Event Hubs for loosely coupled integration between applications.

Chapter 10, Securing AKS Network Connections, explores Kubernetes secrets in more depth, covering different secrets' backends and how to use them. A brief introduction to service mesh concepts will also be covered with the implementation of a practical example.

Chapter 11, Serverless Functions, teaches you how to deploy serverless functions on AKS directly using Kubeless, if the requirement is to provide serverless functions within your organization network. You will also integrate AKS-deployed applications with Azure Event Hubs.

Chapter 12, Next Steps, will direct you to different resources where they can learn and implement advanced features in security, scalability. For this chapter, please refer to: https://www.packtpub.com/sites/default/files/downloads/Next_Steps.pdf
