We are increasingly seeing Arm64 instances in the cloud and on the developer workstation, and there are some benefits to integrating some Arm infrastructure for applications rather than staying x86-only in the cloud. But the actual practice of adding another architecture can lead to a lot of unwinding of invisible technical debt - platform assumptions made in shell scripts, package naming conventions in config scripts, and more. This presentation will take a real-life example, and walk through the little hiccups encoutered when moving from x86-only to x86 and Arm64 heterogeneous Kubernetes clusters, with a goal of helping others follow in these footsteps with a less steep learning curve. We will also look at how common config management tools can make the migration easier.
