Explanation:
Benefits of Cloud Computing
Cloud computing offers the following key benefits:
Business agility:
Flexible scaling: Cloud computing enables consumers to scale up, scale down, scale out, or scale
in the demand for computing resources easily. Consumers can unilaterally and automatically scale
computing resources without any interaction with cloud service providers. The flexible service
provisioning capability of cloud often provides a sense of unlimited scalability to the cloud service
consumers.
• High availability: Cloud computing has the ability to ensure resource availability at varying levels
depending on the consumer’s policy and priority. Redundant infrastructure components (servers,
network paths, and storage equipment, along with clustered software) enable fault tolerance for
cloud deployments. These techniques can encompass multiple data centers located in different
geographic regions, which prevents data unavailability due to regional failures.
