  • 5. Forresters Definition of SOAw ww .w ip ro .c om Crafting an SOA platform to fulfill a vision of continuous business improvement requires a sufficiently robust definition of SOA. Forrester defines SOA as: A style of design, deployment, and management of both applications and software infrastructure in which: Applications are organized into business units of work (business services) that are (typically) network accessible. Service interface definitions are first-class development artifacts, receiving the same degree of design attention (and more) as databases and applications. Quality of service (QoS) characteristics (security, transactions, performance, style of service interaction, etc.) are explicitly identified and specified for each service. Software infrastructure takes active responsibility for managing service access, execution, and QoS. Services and their metadata are cataloged in a repository and discoverable by development tools and management tools. Protocols and structures within the architecture are predominantly, but not exclusively, based on industry standards (such as the emerging stack of standards around SOAP).5 Entire contents 2005 Forrester Research, Inc.

Development deliverables split strongly into services and access channels. Development artifact types proliferate and include much metadata. Architects increase their focus on patterns and infrastructure services. Developers focus tightens around business functionality. Governance becomes a critical issue, touching many platform elements.13 Entire contents 2005 Forrester Research, Inc. All rights reserved.
