3. As an IT manager, you need to host a web service as part of your duty. You need to decide between choosing Server A or Server B to host a Cloud service. Server A contains 4 high-power 4-GHz processors and Server B contains 12 low- power 2-GHz processors. The high-power and low-power processors differ only by clock rate and that each processor can independently serve a different service request. For simplicity, suppose that the service requests are identical; handling each service request requires a processor to execute an identical stream of 1 billion instructions at a CPI of 1. a) [15 points] Suppose the Cloud service to be hosted receives a burst of 4 service requests at a time. Which server will complete each burst of 4 requests faster and is, therefore, the better choice? For simplicity, assume the interval between two bursts of requests is very large and that service requests are distributed evenly between the available processors on each server. Justify your answer quantitatively. b) [15 points] Suppose the Cloud service to be hosted receives bursts of 8 service requests at a time, instead. Which server will complete a burst of 8 requests faster and is, therefore, the better choice? Justify your answer quantitatively. 3.

Answer rating: 100% (QA)

To decide between Server A and Server B to find out which is the better choice for hosting the Cloud service based on burst requests of 4 or 8 at a time we need to calculate the time it takes for each ... View the full answer
