On the 1st October 2009, I participated in a webinar “The Right Way to Do Data Integration for Applications,” hosted by David S. Linthicum, a recognized expert in SOA, Cloud computing and Enterprise Application Integration. It was an event that was very well attended and generated a lot of interest from the attendees judging by the large number and quality of questions that were submitted. I recommend that you listen to the replay and download the associated white paper he wrote on that subject.
David covered some of the limitations he has encountered over the years with the way Enterprise Integration Application (EAI) and Enterprise Service Bus (ESB) technologies deal with the integration of data, deployed in a SOA initiative. (more…)
I am back after a somewhat self-imposed hiatus during which I have been doing some soul-searching, or rather talking to a number of practitioners, experts, thought-leaders and analysts in the integration space. My singular quest was to uncover some real-world myths about SOA.
I spoke to a variety of integration experts – enterprise and application architects, application developers, data architects and data integration developers. During these interesting conversations, we discussed real-world SOA…or let me qualify that term further as real-world “service-orientation.”
Of course we discussed paradigms such as “loose-coupling,” “modularity,” “services,” etc., but more importantly in many cases, we spoke at length about how they were falling short of realizing the promised benefits of SOA. On probing each usage scenario further, I chanced upon a couple of interesting myths about SOA, which I would like to share with you. (more…)
In one of my earlier posts I discussed the need for a sophisticated data services-driven technology serving as the foundation for SOA and BPM.
“Data and processes are intertwined. It will fundamentally change the way organizations think about your roles, and your roles are going to need to evolve”.
At this year’s Data Management Association (DAMA) International Symposium,
Michael is quoted saying that:
“In this world there’s a very loosely coupled user interface from the assembled services that in turn share access to data. SOA exposes data issues to more people, places and processes, and what I tell companies is that without a focus on information management and meta data management they’re going to fail.”
It is in speaking to numerous customers, prospects and technologists that I had gathered that without accurate, consistent and timely information, SOA and BPM deployments will face serious information-centric hurdles, affecting the cost-effectiveness and success of the project. As we move towards more agile architectures, I believe that we need to grow typical process-centric approaches to include information centricity as well.
As Michael states:
“Where we are going is beyond the first generation of BPM and SOA [that is process-centric],” he said, “to the next generation of SOA that is information-centric.”
Observe that the key word here is “information-centric.” Reading such statements from Michael and many others definitely validates the strategy I have been defining for building out an effective IT infrastructure that can benefit from the flexibility of a services and process-driven approach, in the data integration layer. Simply wrapping data access with a web service does not qualify as a sophisticated data service and hence, stringing together such simple services with a BPM tool also does not guarantee agility.
As discussed in Services to Orient your Enterprise Data Layer, Joe McKendrick is of the opinion that neither SOA nor enterprise-application integration alone can effectively handle the enterprise data layer. However, data services delivered within an SOA framework can create a data-abstraction layer to address the complexities seen across enterprise data environments.
I have always said that without serving up good quality, consistent and timely information as a data service or a comprehensive data service built using a sophisticated data integration platform, SOA and BPM deployments will not be able to deliver on their promise of agility.
What are your experiences? What kind of information-centric issues have you run into in your service-oriented deployments? Is inaccurate, stale and inconsistent information passing through your IT infrastructure holding you back?
