An organization is looking to implement an online web-based mail system to allow employees to access email while not on the network. The organization wants to have complete control over the servers…

Public cloud transfers server management and data control to the cloud provider, meaning the organization cannot have complete control over the underlying infrastructure.

Hybrid cloud combines public and private cloud resources, which still involves some degree of third-party provider control over the public-facing portion.

Off-premise hosting - such as colocation at a third-party data center - allows the organization to own and administer their own physical or virtual servers while making services accessible over the internet. This satisfies both requirements: web-based access for remote employees and complete organizational control over servers and data. Unlike public cloud, the organization does not share infrastructure with other tenants and retains full administrative authority over all systems and data.

On-premise hosting keeps servers on the organization's own physical site, which may restrict web-based internet accessibility for remote employees without additional network configuration.
