What is the main function of the Cloud Brokering technology?

The main function of Cloud Brokering technology is to facilitate cloud service selection. This involves acting as an intermediary that helps organizations choose among various cloud service providers to meet their specific requirements. A cloud broker assesses different service options based on factors like cost, performance, and compliance, enabling businesses to efficiently use multiple cloud offerings.

A cloud broker simplifies the decision-making process by providing recommendations based on the organization's needs and can offer integrated management across different cloud environments, which is crucial as many enterprises adopt multi-cloud strategies. This added layer of intelligence in selecting cloud services optimizes resource allocation, enhances agility, and can lead to cost savings.

The other options, while related to cloud computing in general, do not encapsulate the primary role of cloud brokering. Optimizing hardware resources typically pertains more to cloud infrastructure management than to service selection. Enhancing virtual network performance relates to network function virtualization and service quality rather than the selection process. Data backup services focus more on data management rather than the intermediary role of selecting or recommending cloud services.
