Cloud Broker (CSB)
"An entity that creates and maintains relationships with multiple cloud service providers. It acts as a liaison between cloud services customers and cloud service providers, selecting the best provider for each customer and monitoring the services. In an era where there are multiple cloud providers, a single business may decide to store data and run applications with multiple providers. In order to ensure compatibility between applications that live in different clouds, a cloud broker is a system that ensures compatability between cross cloud communication. This is a relatively new field as many businesses are still in the process of moving to the cloud, let alone, running their systems in multiple clouds."
