Introducing Windows Azure- P29:The cloud platform is getting more and more attractive to the computing world. Today, service-oriented architecture (SOA) and aspect-oriented programming (AOP) techniques are widely used in enterprise solutions. A question an IT management team or a software development team may ask is, what is the next trend going to be? Cloud computing seems to be the right answer. | C H A P T E R 4 Windows Azure Application Integration Using WCF Whenever a new technology is introduced to the computing world it raises a lot of questions for an enterprise or organization regarding integration. How do you integrate an application built on new technology into the existing system infrastructure What are appropriate tools to select for integration How do you select the right candidate subsystem to migrate refactor or re-engineer Although Windows Azure provides a revolutionary new platform it is almost impossible for any organization to migrate the entire existing on-premises system and infrastructure into the cloud platform. Therefore integration strategies are extremely important. Even subsystems which are built with Windows Azure technology still need to be integrated together. Microsoft has already provided cloud-computing-based services such as .NET Services SQL Azure and Live Services. These services provide organizations with rich functionality and a broad range of building blocks for integration. Windows Azure offers amazing innovative and attractive features. One of these features is the ability to host an application in the cloud. Not only cloud-based applications but also the on-premises applications can leverage cloud services and applications. As I mentioned to run an application from the cloud is far from the whole story. There is always an integration issue associated with the system architecture design. It should not be too difficult to understand why integration plays the essential role. All applications services and infrastructures involved in a computing system need to be coordinated in data exchange resource sharing status persisting logic synchronizing and so on. All these tasks should be done via integration. No matter what integration strategy an organization plans to use an essential feature of an integration platform is that it must support cross-platform communication.
