Organization A has been expanding and, as a result, is outgrowing the processing capacity
of its on-premise Service A implementation. It is determined that this is due to usage
thresholds of Service A and complex data processing limitations in Database A.
The diagram depicts Organization A's current on-premise environment, where Service
Consumers A.
B and C attempt to access Service A at the same time. Service Consumer A
successfully accesses Service A, which then successfully retrieves the requested data (1).
Service Consumer B successfully accesses Service A, but due to the complex data
structure, the request for the data times out and fails (2). Finally, Service Consumer C
attempts to access Service A, but is rejected because Service A is unable to accept more
concurrent requests.
Organization A is required to continue using its on-premise Service A implementation, with
the exception of Database A, which does not need to remain on-premise. Database A is
dedicated to Service A and is comprised of relational data. Which of the following
statements provides a solution that uses cloud-based IT resources to solve the
performance limitations of Service A and Database A?

Cloud Service Consumer A accesses Cloud Service A (1) that resides in Cloud X.
a private cloud owned by the same organization acting as Cloud Consumer A.
Cloud Service A
processes the message from Cloud Service Consumer A and then sends back a response
with the requested data (2). Next, Cloud Service Consumer A sends a message containing
some of this data to Cloud Service B (3), which resides in public Cloud Y that is owned by
Cloud Provider Y.
After processing the message. Cloud Service B sends back a response
with additional data to Cloud Service Consumer A (4). Finally, Cloud Service Consumer A
writes the data it collected from Cloud Services A and B to Database A (5).
Recently, Cloud Service Consumer A has been required to access Cloud Services A and B
at a significantly higher rate, sometimes over 1,000 times within a given workday. This
increased usage has not affected Cloud Service B' s performance. Cloud Service A,
however, has been generating runtime exceptions, and responses to Cloud Service
Consumer A have become increasingly slow and unreliable. It is determined that this
decline in performance is due to infrastructure limitations within private Cloud X' s
environment. Instead of investing in new infrastructure for Cloud X, it is decided to explore
the feasibility of moving Cloud Service A to Cloud Y instead.
Which of the following statements describe valid financial considerations that can be taken
into account for assessing the feasibility of this move?

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:
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?
