Which of the following best describes a community cloud?

A community cloud is best described as a shared cloud environment designed specifically for a certain group of organizations that share common concerns, such as security, compliance, or specific performance needs. This type of cloud infrastructure allows these organizations to collaborate, share resources, and access services that meet their collective requirements.

The essence of a community cloud lies in its focus on the interests and needs of a select group, which enhances collaboration while ensuring that the necessary controls and policies are in place to address the distinct concerns they share. By pooling resources, these organizations can achieve economies of scale and improved efficiencies while maintaining a level of security tailored to their unique environments.

The other options do not accurately capture the concept of a community cloud. A cloud that is accessible to everyone for free typically characterizes a public cloud, while a private cloud is exclusively dedicated to a single organization. A hybrid cloud combines elements of both public and private clouds, but does not specifically address the shared nature and common interests that define a community cloud.
