A community cloud model is a cloud solution in which infrastructure is shared among organizations that have common interests, goals, or concerns, such as security, compliance, or industry standards. This model would best address the bank's need to leverage cloud computing while maintaining a high level of security and privacy for its data and transactions. The other cloud models are not suitable for this scenario, as they either do not offer enough control over the infrastructure (public cloud), or do not allow for sharing of resources among similar organizations (private cloud and hybrid cloud).
