Azure for Architects - Third Edition

By: Ritesh Modi, Jack Lee, Rithin Skaria

Overview of this book

Thanks to its support for high availability, scalability, security, performance, and disaster recovery, Azure has been widely adopted to create and deploy different types of application with ease. Updated for the latest developments, this third edition of Azure for Architects helps you get to grips with the core concepts of designing serverless architecture, including containers, Kubernetes deployments, and big data solutions. You'll learn how to architect solutions such as serverless functions, you'll discover deployment patterns for containers and Kubernetes, and you'll explore large-scale big data processing using Spark and Databricks. As you advance, you'll implement DevOps using Azure DevOps, work with intelligent solutions using Azure Cognitive Services, and integrate security, high availability, and scalability into each solution. Finally, you'll delve into Azure security concepts such as OAuth, OpenConnect, and managed identities. By the end of this book, you'll have gained the confidence to design intelligent Azure solutions based on containers and serverless functions.

Access and identity for AKS

Kubernetes clusters can be secured in multiple ways.

The service account is one of the primary user types in Kubernetes. The Kubernetes API manages the service account. Authorized Pods can communicate with the API server using the credentials of service accounts, which are stored as Kubernetes Secrets. Kubernetes does not have any data store or identity provider of its own. It delegates the responsibility of authentication to external software. It provides an authentication plugin that checks for the given credentials and maps them to available groups. If the authentication is successful, the request passes to another set of authorization plugins to check the permission levels of the user on the cluster, as well as the namespace-scoped resources.

For Azure, the best security integration would be to use Azure AD. Using Azure AD, you can also bring your on-premises identities to AKS to provide centralized management of accounts and security. The basic...
