Model offers measure for SOA successBy Jon BachmanService-oriented architecture has emerged as the most significant shift in how applications are designed, developed and implemented in the last 10 years.A consortium of software vendors and consultants recently introduced the SOA Maturity Model, which is designed to provide IT decision makers with a framework for benchmarking the strategic value of their SOA implementations and planning. The model is divided into five levels.Level 1: Initial servicesAt the initial stage, an organization creates definitions for services and integrates SOA into methodologies for project development. In a financial-services environment, a Level 1 project may use an application server or an enterprise service bus (ESB) adapter to create Simple Object Access Protocol and HTTP Web service invocations between a management system that places an order and a trading service that accepts the order.Level 2: Architected servicesAt this stage, standards are set for the technical governance of an SOA implementation, typically under the leadership of the architecture organization. Standard SOA infrastructure and components, such as an ESB, a services and policies repository, an exception-management service, a transformation service and a single sign-on service, are used to foster greater reuse of services, as well as provide tight management and control of services across an organization.For more, including Levels 3-5, please click here.Bachman is senior director of product marketing at Sonic Software.
