Who among the following adds and extends value to the cloud-based services for customers?

The correct choice is a cloud services brokerage. A cloud services brokerage acts as an intermediary between cloud service providers and customers, offering a variety of services that enhance the value of cloud offerings. These brokerages can provide tailored solutions, integration of services from multiple providers, and additional features that meet specific business needs. By aggregating services from different providers, they help customers navigate the complex landscape of cloud solutions, enabling businesses to customize their cloud experience and leverage the best services for their requirements.

In contrast, a cloud service provider delivers the actual cloud services, such as computing power, storage, or software applications, but does not necessarily enhance or add value beyond what is offered in their standard packages. A cloud backup service provider focuses specifically on providing backup solutions rather than extending services across various cloud offerings. A cloud service auditor evaluates and assesses the security, compliance, and performance of cloud services but does not extend or add value to those services for customers.
