Question
A solutions architect needs to review the design of an Amazon EMR cluster that is using the EMR File System (EMRFS). The cluster performs tasks that are critical to business needs. The cluster is running Amazon EC2 On-Demand Instances at all times for all task, master, and core nodes. The EMR tasks run each morning, starting at 1:00 AM, and take 6 hours to finish running. The amount of time to complete the processing is not a priority because the data is not referenced until late in the day. The solutions architect must review the architecture and suggest a solution to minimize the compute costs. Which solution should the solutions architect recommend to meet these requirements?
Options
- ALaunch all task, master, and core nodes on Spot Instances in an instance fleet.
- BLaunch the master and core nodes on On-Demand Instances.
- CContinue to launch all nodes on On-Demand Instances.
- DLaunch the master and core nodes on On-Demand Instances.
