Q: 8
A cloud consumer is interested in leasing cloud-based virtual servers. It compares the virtual servers
offered by Cloud Provider X and Cloud Provider Y. Cloud X (owned by Cloud Provider X) and Cloud Y
(owned by Cloud Provider Y) both provide shared physical servers that host multiple virtual servers
for other cloud consumers. The virtual servers on Cloud X are accessed directly, whereas the virtual
servers on Cloud Y are accessed via an automated scaling listener. On Cloud X, virtual servers are pre-
configured to support a specific amount of concurrent cloud service consumers. When this threshold
is exceeded, cloud service consumer requests are rejected. Due to the use of the automated scaling
listener, virtual servers on Cloud Y can provide a greater level of elasticity.
The hourly cost to the cloud consumer to use a virtual server on Cloud X is half that of the cost to use
a virtual server on Cloud Y. Within a one month period, Cloud Provider X bases its hourly charge on
the maximum number of virtual servers used. Within a one month period, Cloud Provider Y bases its
hourly charges on actual virtual server usage. Cloud Provider Y charges $20 for each hour that a
cloud consumer uses a virtual server. The cloud consumer predicts its monthly usage requirements
to be as follows:
Number Of Virtual Servers
Usage
3
20 Hours
4
30 Hours
5
50 Hours
The cloud consumer is required to choose the cloud provider with the lowest on-going cost, based on
its predicted usage. Which of the following statements accurately calculates the on-going usage costs
of Cloud Providers X and Y and correctly states the cloud provider that the cloud consumer must
choose?
