Our clients are facing a number of questions with direct implications on how their IT environment will be managed Architecture and Design is an Integral Part of Building an IT Solution Vision An Enterprise technical architecture will promote uniform design, development, and deployment of capabilities that will reduce the complexity of the environment, enhance developer productivity, and decrease time to market. The envisioned solution should include the following characteristics: Leverages existing information system assets, while reducing maintenance costs Utilizes of multiple technologies that facilitate dynamic messaging Accommodates new, unforeseen information sources and deployment Exploits Internet/Intranet technologies to implement groupware and workflow Facilitates evolutionary migration toward distributed component/object technologies Leverages industry standards (CORBA, UML, XML) The Ideal Architecture . . . A Service Oriented Architecture is a natural “stepping stone” toward true systems interoperability Requirements for cross platform transactional services and data access dictate that the software infrastructure should ultimately support a message broker architecture Near term benefits can be obtained by deploying packages as unique components of a service oriented architecture which address distribution, interface and semantic integration issues Increases in adaptability and autonomy can then be obtained over time through incremental deployment of transformational brokering components as they mature Service Oriented and Message Broker Architectures Architecture Dimensions KPMG believes that the type of architecture being addressed can be characterized by three dimensions Scale:Scope of concerns/ issues to be addressed Domain: Subject Area requiring specific business or technical knowledge Specificity: Level of detail Using this structure KPMG assists clients in clearly articulating the interdependencies of the architectural elements within their env
