Final answer:
The Community Cloud is a cloud computing approach that allows multiple organizations with common interests to share a cloud infrastructure, balancing the benefits of private clouds with the cost-effectiveness of shared resources.
Step-by-step explanation:
The cloud computing method that enables multiple organizations with common interests to share the cloud infrastructure is known as the Community Cloud. Unlike the public cloud, which is accessible by the general public, or the private cloud, which is reserved for a single organization, the community cloud allows a group of organizations to access a shared cloud environment. This setup often comes with a set of shared policies and values, making it an economical and practical option for collaboration.
Community clouds provide many of the same benefits as private clouds, such as more control over privacy and security, but at a shared cost among the users. This makes it particularly beneficial for organizations such as governmental agencies, research institutions, and businesses in similar industries that need to collaborate but also wish to maintain a higher level of control and security over their data.
