Building Multi-Architecture Container Images

Introduction

Over the past several years, we’ve seen the emergence of the ARM64 architecture, which is gaining popularity due to its energy efficiency and performance benefits. We often seen these processors in mobile devices, such as smartphones and tablets. We also seen them in our IoT devices, such as smartwatches and smart TVs. Now, we are starting to see increased adoption of ARM64 processors in servers and personal computers.

This emergence of the ARM64 architecture, means that we now have two major processor architectures to consider when building and deploying our containerized applications in order to maximize our application’s reach.
