Overview

Besides being a popular buzzword, SOA is nothing more than a pragmatic style of enterprise architecture that focuses on implementing business processes via integration of various IT systems. Emphasis on loosely-coupled services with clearly defined contracts helps to protect a software-ecosystem from side-effects introduced during the course of modification within individual legacy applications. Adherence to industry standards particularly in BPM and orchestration areas minimizes the cost of IT adaptation to the changing business landscape. Contrary to a traditional integration hub, a SOA ownership is federated and thus easy to spread across department boundaries.

A common misperception is to consider SOA just a purely technological approach limited to particular protocols (SOAP/WS-stack), a service mediation technology (ESB), or a single solution from a particular vendor. Implementing SOA is about creating enterprise architecture that instantly adjusts to the business needs and can be effectively operated within budget constraints. Typically a SOA-program is planned and executed by the company's own IT-department; however, the program’s demands often exceed their capabilities. The logical choice is to rely on the expertise of a qualified outsourcing partner.

Traditional SOA methodologies are typically of the waterfall-style and are based on an extensive up-front effort to produce an ideal IT-ecosystem design. The Exigen Services approach combines industry-leading Agile expertise and strict SOA program governance. This enables application of evolutionary design principles to SOA implementations that results in higher ROI even on the very first step of the roadmap.
