An IT manager is reviewing essential cloud computing characteristics to align organizational requirements with cloud deployment features. Match each cloud characteristic on the left with its correct operational description on the right.
- Rapid ElasticityDynamically allocating and releasing resources automatically to scale seamlessly outward and inward with fluctuating demand.
- On-Demand Self-ServiceProvisioning computing capabilities, such as server time or network storage, automatically without requiring human interaction with the service provider.
- Resource PoolingServing multiple consumers using a multi-tenant model where physical and virtual resources are dynamically assigned according to demand.
- Measured ServiceMonitoring, controlling, and reporting resource usage transparently for both the provider and consumer based on metered utilization.
Cevap
Rapid Elasticity matches automatic dynamic scaling outward and inward based on demand. On-Demand Self-Service matches provisioning computing resources automatically without human interaction. Resource Pooling matches serving multiple clients via a multi-tenant model with shared physical infrastructure. Measured Service matches monitoring and reporting usage transparently based on metered metrics.
Each cloud characteristic corresponds to a distinct NIST standard cloud feature: Rapid Elasticity provides automated real-time scaling; On-Demand Self-Service allows user provisioning without provider interaction; Resource Pooling aggregates infrastructure for multi-tenancy; and Measured Service meters usage for transparent tracking and billing.
