The cloud provider's use of shared resources allows your organization to save costs by pooling computing resources with other clients. This approach enables economies of scale, as the provider can offer services to multiple tenants at a reduced cost due to the aggregated demand for resources. Rapid elasticity and high availability are also attributes of cloud resources, but they don't specifically denote the benefit achieved from the sharing of resources. Multiple user accounts and layers of security are often features provided by the cloud services but are not inherent benefits of shared resources alone.
