Kubernetes can help protect us against this. It can enforce limits on the maximum amounts of CPU and RAM that any one pod can use. It can also provide guarantees for minimum amounts that will always be available to pods. And maybe that's a better way to think about the problem. By guaranteeing that everything has enough resources, the neighbors can be as noisy as they like, because we know that every pod will have sufficient resources to do what it needs to do. If there are free resources that no one needs, why not use them. So let's take a look at how that works. This is another example of describing your pod to Kubernetes.
