Setc. How EDA extends SOA and why it is important. [Download extended PDF] See also: Why to distinguish between SOA and EDA Moving toward on-demand business Organizations tend to change their structure frequently. The evolving focus on service orientation and globalization will enforce this trend. The world is preparing for network oriented business structures with independent autonomous service providers and service consumers. SOA, false promise? This requires loosely coupled application components to be able to easily put the scissors in the organization structure without disturbing the supporting IT-systems. IT-flexibility versus organization flexibility Of course the use of SOA has benefits.
At the moment SOA is positioned in the market mostly as a type command-and-control architecture at the higher granularity levels of functional decomposition. But why is SOA promoted at this level of granularity? When to use SOA and when to use EDA? In contrast to SOA, EDA provides a way of loose coupling. Redundancy: strong design Visualization. Why doesn't anyone understand SOA? If you read the numerous technology blogs daily like I do, you soon realize that most people still don't understand SOA. Today I read this article from Joe McKendrick called Why even the best SOAs are stalling. In this article Joe discusses an article by Anne Thomas Manes where she discusses how she has only come across one company that has realized any value from SOA.
In her article she referred to an article from Ron Schmezler at Zapthink called Why Service Consumers and service providers should never directly communicate. Apparently this article caused all kinds of heated debate on the message boards. ....this technology discussion is irrelevant.....It has become clear to me that SOA is not working in most organizations. So why are so many organization struggling with SOA? Business ValueThe business gets value when SOA is used as an enabler of BPM. IT ValueThe value for IT is in reuse and speed to market. Defining SOA as an architectural style. » Analyst: Wall Street doesn’t quite get SOA yet | Service-Orien.
To paraphrase Gordon Gekko, is SOA a "dog with fleas"? Shouldn't analysts be excited over the prospect that enterprises are finally getting the tools and knowledge they need to break down their internal silos and move forward with confidence into the new digital realm? Would Gekko, the corporate raider in the movie Wall Street, touch an SOA company with a 10-foot pole?
Trip Chowdhry, a managing director of equity research at Global Equities Research, recently joined in on one of Dana Gardner's recent SOA BriefingsDirect podcasts, and explained why he -- and the rest of Wall Street -- isn't quite sold on the promises vendors have been making as of late around SOA. Vendors are scrambling to build a product category where there is no tangible product, and no specific demand for one.
Trip's message is very simple and straightforward: Vendors, please start making some sense to the rest of the world when it comes to SOA. Trip pointed to everyone's favorite poster child of complexity -- SAP. » Wanted, desperately: more SOA movers and shakers. An enterprise architect "drought" looms, and this may slow down many SOA efforts over the coming year. In a new prediction issued within the past couple of weeks, ZapThink's Ron Schmelzer has sounded the alarm that there simply won't be enough SOA proponents to fill the burgeoning demand for new SOA projects.
"First, there is a significant demand in the marketplace for experienced SOA talent. Second, we are seeing a burgeoning of SOA consulting companies that offer kick-start approaches to SOA in which they supply the experienced architects and their customers supply the heavy-lift labor to implement the Services. Already we’re starting to see a bifurcation in the IT community between architect and developer, with development seen as an increasing commodity whereas architecture is an increasing scarcity. " In a new interview, Miko Matsumura, vice president of WebMethods, also expresses concern that SOA movers and shakers in organizations may be too few and far between.
Thought Leadership: Gartner highlights Top 10 Strategic Technolo. Gartner published their list, so I shall also publish mines... Here is Gartner's List: Open Source: I wonder if they will start showing non-commercial open source in their Quadrants? Virtualisation: Virtualization can be done in a variety of ways from Azul to VMWare/Xen to Wyse Terminals. I look forward to them comparing across virtualization approachesService Registries and Repositories: I know at work, we have had a registry for several years now and the same can be said of most other large enterprises.
Anyway, my list is a little different and just a little deeper: Open Source: No it won't be more of the Linux, Ruby, repeat after me stuff but the savage pursuit of open source within an industry vertical contextIdentity Management: If you aren't already doing it, you will be. » Surprise - SOA does have a business bent | Service-Oriented Ar. Are SOAs being launched to actually help the business, or to improve the productivity of technology departments? The ultimate goal is about the business, of course, but that's awfully difficult to measure as of yet.
It seems most SOA efforts these days are in pursuit of something more tangible and measurable, that is, IT productivity. x hours of developers' time is saved by using standardized service components and interfaces. Recently, I talked about the SOA implementation at Ameriprise Financial, which measured savings of at least $10 million from service reuse.
Business benefits were a bit more squishy, but Ameriprise was measuring results against some "what-if" analysis to determine the course and costs of a non-SOA route taken. Business benefits may be squishy to measure, but its what companies want from SOA Yet, a new survey of 313 enterprises conducted by ebizQ finds that business -- not IT -- goals are driving most SOA implementations these days.
