A company is subcontracting part of a large project to another company. Management wants to ensure that there is a secure way for employees from both companies to share data without exposing internal

A hybrid cloud combines public and private clouds, primarily for extending private resources to the public cloud or for disaster recovery, but it doesn't directly address secure data sharing between two distinct companies as its primary purpose.

A public cloud is available to the general public, and while secure data sharing can be configured, it typically lacks the inherent, dedicated isolation and common policy framework for specific collaborating entities found in a community cloud.

A private cloud is dedicated to a single organization and does not inherently facilitate secure, controlled data sharing with an external, distinct company without significant custom integration.

A community cloud is specifically designed for multiple organizations with common interests (like collaborating on a large project) to share infrastructure and resources in a secure and isolated manner. This allows data sharing among authorized members while preventing exposure of internal, non-project-related information to outsiders.
