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 1500 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.
