Realizing SOAs and the role of The Open Group’s SOA Reference Architecture

Ali Arsanjani, Distinguished Engineer
CTO Business Performance & Service Optimization, IBM

Nikhil Kumar
President and CEO, Applied Technology Solutions, Inc. (ApTSi)

The Open Group’s SOA Reference Architecture (RA) and the Open Group Service Integration Maturity Model (OSIMM) can be effectively used to create organizational SOA RA’s. This presentation has the goal of providing practitioners with an actionable approach to assess and design a real-life SOA, and is based on the presenters real life experience in the realization of SOA RA’s and roles as co-chairs of the SOA RA for the Open Group. In this presentation Nikhil and Ali will present a quick overview of the SOA RA, its key principles, an understanding of how we map from Capability to ABB to SBB, and what it means in the day in the life of a Service and a SOA. Articulating the message to the different stakeholders of the RA in an organization is critical in making the RA an actionable asset. We will illustrate this with an example and use a “day-in-the-life” model of a SOA and a Service, and its mapping to the OSIMM and SOA RA to show how to realize and assess the RA. The “day-in-the-life” model provides a very useful tool for architects and practitioners to view SOA and the RA from different perspectives and communicate decisions to stakeholders, by helping answer the question “what does it mean to me”. Mapping it to the RA and the OSIMM lets us assess and plan the SOA.
