What do we call a cloud environment created by a company for its own use, focusing on security?

A cloud environment created by a company for its own use, with a primary focus on security, is known as a private cloud. This type of cloud architecture is dedicated exclusively to one organization, providing the company with greater control over its data, security measures, and compliance requirements. In a private cloud, infrastructure is typically hosted on-premises or through a third-party service provider, but the critical aspect is that the resources are not shared with other organizations, which inherently enhances security.

Private clouds offer tailored configurations and can be optimized to meet the specific operational needs of that organization, such as data privacy and regulatory compliance. These features are especially advantageous for industries handling sensitive information, like finance or healthcare, where regulatory requirements for data protection are stringent.

In comparison, other cloud types like public clouds involve resources that are shared among multiple users and organizations, while hybrid clouds combine both private and public resources, and multi-cloud environments leverage services from multiple providers. Each of these alternatives carries different security models and implications that may not align with the focused security requirements of a single organization.
