A company requires a deployment model dedicated solely to them, hosted either on-premises or by a provider. Which model fits this requirement?

A private cloud is a cloud computing environment dedicated exclusively to a single organization. This model offers enhanced security, control, and customization, as the infrastructure is not shared with other tenants. It can be hosted on-premises within the company's own data center or by a third-party provider who dedicates the infrastructure to that single client. Public cloud is incorrect because it involves shared infrastructure accessible over the public internet. Hybrid cloud is incorrect as it combines public and private clouds, which doesn't fit the "dedicated solely to them" requirement for the entire environment. Multi-cloud is incorrect because it involves using multiple public cloud providers, again not meeting the single-tenant dedication.
