Let's assume that an organization needs to process large amounts of data in bursts, on a cloud-based Kubernetes cluster. For instance: each Monday morning, they need to run a batch of 1000 compute jobs of 1 hour each, and these jobs must be completed by Monday night. What's going to be the most cost-effective method?

• A.Commit to a specific level of spending to get discounted prices (with e.g. "reserved instances" or similar mechanisms).
• B.Run a group of nodes with the exact required size to complete the batch on time, and use a combination of taints, tolerations, and nodeSelectors to reserve these nodes to the batch jobs.
• C.Leverage the Kubernetes Cluster Autoscaler to automatically start and stop nodes as they're needed.
• D.Use PriorityClasses so that the weekly batch job gets priority over other workloads running on the cluster, and can be completed on time.
