A company is actively moving business applications to an ITaaS model. The IT department
increasingly acts as an adviser, proposing the best fit from either private cloud capability or public
cloud suppliers.
The company’s finance department is considering their financial applications for cloud as they

increasingly need more capacity and better performance at the end of the month, which the
current infrastructure cannot deliver. The financial application architecture is three tier
(presentation, middleware, and database).
The IT security team has suggested that with appropriate controls the presentation layer could be
deployed in a public cloud but the middleware and database layers cannot.
What would be the best approach to enabling service elasticity in this scenario?

A.
IaaS deployment in the hybrid cloud

B.
IaaS deployment in the public cloud

C.
IaaS deployment in the private cloud

D.
IaaS deployment in the community cloud
