CV0-002 · Question #457
A cloud architect is deploying a VM in a public IaaS cloud. The software that will be installed on the VM is not compatible with any of the OS versions in the system images offered by the IaaS vendor.
The correct answer is D. Host the server on premises and integrate it with the IaaS service using the hybrid cloud model.. When an application requires an operating system incompatible with standard IaaS images, and potentially even custom images, hosting the server on-premises and integrating it into a hybrid cloud model is often the best solution.
Question
A cloud architect is deploying a VM in a public IaaS cloud. The software that will be installed on the VM is not compatible with any of the OS versions in the system images offered by the IaaS vendor. Which of the following is the BEST way to deploy a VM with the required OS?
Options
- ADevelop a VM image on an on-premises hypervisor and send it on a physical hard drive to the cloud
- BUse a bare metal service instead of IaaS and verify that the bring-your-own OS feature is available.
- CDevelop a VM image on an on-premises hypervisor and upload it to the cloud via API.
- DHost the server on premises and integrate it with the IaaS service using the hybrid cloud model.

Why each option
When an application requires an operating system incompatible with standard IaaS images, and potentially even custom images, hosting the server on-premises and integrating it into a hybrid cloud model is often the best solution.
Sending a physical hard drive is an outdated, slow, and generally unsupported method for deploying VM images to modern public clouds.
Bare metal services are a different service model than IaaS VMs and may not be suitable if the overall solution requires IaaS VM capabilities for other components.
Uploading a VM image via API assumes the custom OS is compatible with the underlying IaaS hypervisor, which might not be true for highly specialized or legacy operating systems.
If the required operating system is not compatible with the IaaS vendor's virtualization platform, even via a custom image upload, then hosting the server on-premises is necessary. A hybrid cloud model allows this on-premises server to securely connect and interact with other cloud-based resources, effectively integrating the incompatible OS into the overall cloud architecture.
