Which cloud model allows resource sharing based on operational requirements?

The community cloud model is designed specifically for sharing resources among a group of organizations that have common concerns, such as compliance, security, or jurisdiction. In this model, the cloud infrastructure is shared by several organizations, enabling them to cooperate and share infrastructure costs while meeting their operational requirements. This allows for enhanced collaboration and resource utilization, as the cloud can be tailored to the specific needs of the community it serves.

The operational requirements are met through shared governance and policy alignment among the community members, which facilitates optimized use of resources based on collective requirements. This often results in improved efficiencies and cost savings for the organizations involved, as they are leveraging a shared infrastructure rather than each individually provisioning their own isolated resources.

In contrast, other models such as public and private clouds typically cater to single entities or a broad public audience, with less emphasis on collaborative resource sharing tailored specifically to a defined group. The hybrid cloud model combines elements from both public and private clouds and doesn't focus specifically on a community of users with aligned interests; rather, it aims to leverage the benefits of both cloud types, which does not necessarily imply resource sharing based on operational requirements.
