Cloud Broker
An entity that manages the use,
performance and delivery of cloud services and negotiates relationships
between Cloud Providers and Cloud Consumers.
As cloud computing evolves, the integration of cloud services can be too complex for cloud consumers to manage.
The major services provided by a cloud broker include:
1) Service Intermediation
A cloud broker enhances a given service by improving some
specific capability and provides the value-added service to cloud
consumers.
2)Service Aggregation
A cloud broker combines and integrates multiple services
into one or more new services. The broker will provide data integration
and ensure the secure data movement between cloud consumer and multiple
cloud providers.
3) Service Arbitrage
Service arbitrage is similar to service aggregation, with
the difference in that the services being aggregated aren’t fixed.
Service arbitrage allows flexible and opportunistic choices for the
broker. For example, the cloud broker can use a credit-scoring service
and select the best score from multiple scoring agencies.
2. Gartner
A cloud services brokerage is a business model in which a
company or other entity adds value to one or more (generally public or
hybrid, but possibly private) cloud services on behalf of one or more
consumers of those services.
