Should you use small or large instances in a Kubernetes cluster? It depends. You should consider a few factors when selecting an instance type:
- What kind of workloads you deploy (i.e. memory and CPU requirements).
- The blast radius you can tolerate.
- How you design your HA strategy.
- How many resources are available to the pods.
