Balancing Cost with Performance and Reliability

Kubernetes cost optimization comes down to pinpointing the correct resource allocations and auto-scaling factors for our workloads.

But "correct" in this context doesn't mean "the least possible amount of resources". It's a delicate interplay of cost vs. performance vs.reliability.

In order to run our clusters in the most cost-effective way without compromising either performance or reliability it's vitally inportant to understand the Pod QoS model and the implications of PodDisruptionBudget.
