Assume that there are three node configurations with different disk capabilities: an HDD-based node, an SSD-based node, and a node with no local disk. Furthermore, assume that the cloud vendor will place any data that you request in the local disk (if any) before your task starts, and will do so for free. Nodes with no local disk cost $0.30 per hour. The network has throughput of 0.1 GB/s per node. The HDD-based node has throughput of 0.2 GB/s, a storage capacity of 2 TB and costs $0.50 per hour. The SSD-based node has throughput of 1 GB/s, a storage capacity of 0.5 TB and costs $1.50 per hour. Assume the dataset volume is 1 PB. The business needs of your organization dictate that any aggregate L/O throughput above 500 GB/sec is acceptable. (The aggregate I/O throughput is the sum of the throughput across all nodes.) 15 points] For each configuration, how many nodes are needed to meet this goal and what is the total cost?
