Azure Containers Explained

By: Wesley Haakman, Richard Hooper

Overview of this book

Whether you’re working with a start-up or an enterprise, making decisions related to using different container technologies on Azure has a notable impact your app migration and modernization strategies. This is where companies face challenges, while choosing the right solutions and deciding when to move on to the next technology. Azure Containers Explained helps you make the right architectural choices for your solutions and get well-versed with the migration path to other platforms using practical examples. You’ll begin with a recap of containers as technology and where you can store them within Azure. Next, you’ll explore the different Microsoft Azure container technologies and understand how each platform, namely Azure Container Apps, Azure Kubernetes Service (AKS), Azure Container Instances (ACI), Azure Functions, and Azure App Services, work – you’ll learn to implement them by grasping their respective characteristics and use cases. Finally, you’ll build upon your own container solution on Azure using best practices from real-world examples and successfully transform your business from a start-up to a full-fledged enterprise. By the end of this book, you’ll be able to effectively cater to your business and application needs by selecting and modernizing your apps using various Microsoft Azure container services.

The future of AKS

As you may have gathered from reading this book, AKS is an ever-evolving service. Just in the last half of 2022, the networking part of AKS has grown from two container network interfaces (CNIs) to having the ability to bring your own CNI, the next iteration of the Azure CNI, with the added ability to dynamically assign IP addresses when needed. We then also got an extra feature of the Azure CNI, allowing it to use an overlay network. And near the end of the year, we got the option to run Azure CNI powered by Cilium, bringing an eBPF dataplane with it. Additionally, features such as Fleet allow us to manage AKS clusters at scale, and technologies such as Draft V2 allow us to quickly generate deployment files so we can also deploy at scale. In this section, we will take a look at each of these technologies.
