As the enterprise elastically provisions resources, what is a possible solution if the hypervisors are different?

A European company has been providing web services within their private cloud. They now wish to make these web services available globally by using a public cloud provider. You are hired as a cloud architect to help them with this transition. In your analysis, you find that a different hypervisor is being used by the public cloud provider.

As the enterprise elastically provisions resources, what is a possible solution if the hypervisors are different?
A . Modify the access role in the current service template to allow connection to the public cloud
B . Recalibrate the current service template and deploy it in the public cloud
C . Define a different service template to deploy in the public cloud
D . Use a second service catalog to deploy the existing service template in the public cloud

Answer: C

Explanation:

Since the orchestration engine is really multiple layers of software working together to create a service, it is critical that all of the layers can talk to each other. Hypervisor integration is critical, but one should also consider that hypervisors may be different between the internal and public clouds. The service catalog orchestration component needs the ability to talk to different hypervisors. Otherwise, an intermediate step will need to be developed for translation or conversion with the other hypervisor. Automation of this intermediate step may require extra development. Similar situations may occur with integration with physical resources or other management processes like metering and chargeback.
