Assume that the MapReduce job from Page #438 in Section 6.2 is executing a task with 2^40

Question:

Assume that the MapReduce job from Page #438 in Section 6.2 is executing a task with 2^40 bytes of input data, 2^37 bytes of intermediate data, and 2^30 bytes of output data. This job is entirely memory/storage bound, so its performance can be quantified by the DRAM/Disk bandwidth of Figure 6.6.

a. How much does the job cost to run on m4.16xlarge and m4.large in Figure 6.15?
Which EC2 instance provides better performance? Which EC2 instance provides better cost?

b. How much would the job cost if an SSD was added to the system, as in m3.
medium? How do the performance and cost of m3.medium compare with the best instance from part (a) above?
