A company is transitioning business applications to an ITaaS model. The IT department increasingly acts as an adviser, proposing the best fit from either a private cloud capability or public cloud suppliers.
The finance department is evaluating financial applications for cloud because 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. However, the middleware and database layers cannot be deployed in that way.
What would be the best approach to enabling service elasticity in this scenario?
A. IaaS deployment in the public cloud
B. IaaS deployment in the hybrid cloud
C. IaaS deployment in the private cloud
D. IaaS deployment in the community cloud
