- Sep 26, 2016
In this sample chapter from Intercloud: Solving Interoperability and Communication in a Cloud of Clouds, authors Jazib Frahim, Venkata Josyula, Monique Morrow, and Ken Owens explore how cloud providers have set up data centers at many locations to service their customers. For example, Amazon, Google, Microsoft, Salesforce.com, and others have established data centers for hosting cloud application services such as social networking, gaming portals, and business applications. In many of these social
networks, the service components run in separate virtual machines that may be hosted in data centers owned by different cloud computing providers. In order to link the services provided by different providers at different locations around the world and to provide quality service to a consumer, it is necessary to build an Intercloud to bring the services together. This chapter details Intercloud architecture mode, Intercloud use cases, and Intercloud deploy.
