On average, Kubernetes nodes running on ARM instances are 20% cheaper than their AMD counterpart. Optimising your cloud bill is tempting, but how do you seamlessly migrate existing workloads to a different architecture? And how do you do it at scale, with more than 4000 engineers and 30 clusters in 4 regions? In this episode of KubeFM, Thibault and Miguel explain how Adevinta built an internal platform on Kubernetes for mixed AMD and ARM workloads. You will learn: The challenges they faced with validating containers for mixed architecture with a mutating webhook and the open source solution they came up with: noe. Building an internal platform requires careful planning and designing simple interfaces that are backwards compatible. How to not DDoS your container registries. How to onboard users to an internal platform and evangelise it.
