Which EBS volume should you recommend?

You work for a market analysis firm who are designing a new environment. They will ingest large amounts of
market data via Kinesis and then analyze this data using Elastic Map Reduce. The data is then imported in to a
high performance NoSQL Cassandra database which will run on EC2 and then be accessed by traders from
around the world. The database volume itself will sit on 2 EBS volumes that will be grouped into a RAID 0
volume. They are expecting very high demand during peak times, with an IOPS performance level of
approximately 15,000. Which EBS volume should you recommend?

C is the right answer.
Provisioned IOPS (PIOPS) is the highest-performance SSD volume designed for mission-critical applications. Max. IOPS**/Volume is 20,000 so even in peak time the demands are fulfilled. Moreover, Cassandra is highly supported with Provisioned IOPS so C is the best choice.
