Developments in SOA

Printer-friendly version

This webinar is the first in the series SOA in the Digital Age. In it, a panel of experts discusses how Service Oriented Architecture has developed.

The event took place on Tuesday, March 10, 2015. A video recording is available here. It has been edited to remove unnecessary material ("housekeeping" etc.) while retaining the entire discussion. A written digest of the webinar is available here. The questions asked in discussion have been posted to the SOA Standards Discussion Forum.

SOA was launched as a technical architecture based on the business concept of service. Product vendors and their customers adopted it with equal enthusiasm, but applying the idea to real systems was harder than it looked. Disenchantment set in. Analysts stopped recommending SOA.

Use of service-orientation grew steadily in spite of this, as architects learned how to make it work. Now it is accepted as an underlying principle for successful deployment of cloud computing and other digital technologies. What have we learned? How has SOA changed?

The panel discussing these questions consisted of John Bell and E.G. Nadhan. They are experts who have used SOA, architected SOA products, were involved in the early days, and are following the latest developments.  Ali Arsanjani, who had also planned to be on the panel, was unfortunately on a delayed airplane flight at the time of the webinar. The discussion was moderated by Chris Harding.

Dr. Ali Arsanjani is a Distinguished Engineer and CTO Smarter Process, ECM, SOA and Emerging Technologies with IBM. He specializes in analytics and enterprise content management, and is a leader of the Smarter Process Method Community and the SOA Community within IBM. He is an IBM Master Inventor, chair of the Wireless, Pervasive and Digital Media IDT, and is a member of the IBM Academy of Technology. Ali has been a leader of SOA methodology since the early days. He was instrumental in the development in IBM of the work that became the basis of the Open Group SOA Reference Architecture and the Open Group Services Integration Maturity Model (OSIMM). The OSIMM is now an International Standard, and the reference architecture has been a major influence on the international standard reference model being developed by ISO. As evidenced by his current role, he continues to work at the leading edge of SOA evolution.
John Bell has been a user of SOA since its early days, with significant experience of establishing a service-oriented enterprise architecture and deploying SOA solutions within a major corporation. He is now also involved in standards activity, as chair of the IEEE SOA and Web Services Working Group, and as co-chair of the Open Group project to maintain alignment between Open Group, IEEE and ISO SOA reference architecture work.
E.G Nadhan is a Distinguished Technologist at HP. As the Lead Technologist for Global Strategic Capabilities within HP Enterprise Services (Applications), he orchestrates the definition and sustained evolution of the current and future tooling landscape in the context of HP's standard processes as well as cross-cutting themes including Open Source, Cloud Computing, Configuration Management and Agile Development. He was a co-chair of the Open Group Service-Oriented Cloud Computing Infrastructure (SOCCI) project, and currently co-chairs the Cloud Computing Governance project. Nadhan is a widely recognized author and speaker at industry conferences including the Open Group, HP Technology Forum, HP Software Universe conferences and has co-authored multiple books with Microsoft Corporation as well as The Open Group.
Dr Chris Harding is the Director for Interoperability at The Open Group. His role includes supporting the work of Open Group members on SOA and on Open Platform 3.0™, and he has been Forum Director of the SOA Work Group since its inception in 2005. He contributes to on-line journals, speaks at events, and is a frequent webinar panelist and moderator, within and outside The Open Group.
