Cloud Infrastructure Deployment Benefits

D.

The benefit that is offered by a cloud infrastructure deployment but is lacking in an on-premises deployment is efficient scalability, option D.

Cloud infrastructure allows for efficient scalability because the underlying technology is designed to automatically allocate and de-allocate resources as needed to support the application workloads. This means that resources can be quickly scaled up or down in response to changes in demand without the need for manual intervention or the purchase of additional hardware.

In contrast, on-premises infrastructure typically requires significant upfront investment in hardware and software, and it may not be possible to easily scale up or down as needed. This can result in wasted resources and increased costs, as well as slower response times to changing business needs.

Virtualization, option A, and storage capacity, option C, are benefits that can be found in both cloud and on-premises deployments. Virtualization allows for the creation of multiple virtual machines on a single physical server, while storage capacity refers to the amount of data that can be stored on a given infrastructure.

Supported systems, option B, is not a benefit offered exclusively by cloud infrastructure deployment, as on-premises deployments can also benefit from vendor support for their systems.
