The uptake of general-purpose service enablement is by no means a hockey stick trend line. The adoption patterns some five years into the SOA evolutionary path do not show a "slam dunk" demand effect. The role, impact and importance of SOA is, in fact, ambiguous ... still. Many see it as merely an offshoot of EAI, rather than a full-blown paradigm shift.
Meanwhile, some other trends that do demonstrate more of a hockey stick adoption pattern -- social media, Ruby/Phython, RESTful interactions, and RIAs -- are worth a fresh look in the context of SOA. The new kids on the innovation block are experimenting at break-neck speed with social media, social networking, Ruby on Rails, SaaS, Python, REST and the vital mix of rich Internet application (RIA) approaches.
Something is going on here that shows the compelling attraction of better collaboration and sharing methods, of self-defining social and work teams, of faster and easier applications development, of not moving old systems to the Web but just moving to the Web directly, and the recognition that off-the-wire applications with fine UIs are the future.
A lot of these issues surfaced in a face-off last night between Salesforce.com CEO Marc Benioff and SAP Chairman Hasso Plattner.
So who's on first, SOA or Web oriented architecture (WOA)? These Web-facing trends for the time being may remain outside the strict boundaries of enterprise IT -- but they are of great interest to developers, ISVs, welling Web 2.0 services start-ups, and cloud compute purveyors.
These technologies and techniques are also clearly on the radar of forward-looking innovators inside of businesses large and small. Indeed, those non-IT influencers inside of corporations with a keen eye on the all-important Internet growth opportunity are the constituency to win over, and they are not sold on SOA.
If these methods and tools work for a handful of developer entrepreneurs in proverbial garages with credit-card balance-sized investment requirements, then why wouldn't the same solutions be scalable and relevant to the more established business world? Reaching customers quickly with compelling products and services that exploit and leverage the Internet -- this is the same for General Motors, Sprint and Dick-and-Jane startups alike.
The startups often have advantages -- because, among other things, they don't need a SOA, they don't need to integrate with 15 different back-end systems, they don't need to wield the political power inside a bureaucracy necessary to get anything done. Success requires the best of start-ups and the best of what large, well-capitalized corporations can do. But the balance may be shifting to the fleet and Agile side of the equation.
So I'm wondering now whether the window for holistic SOA deployment and value, as it has been classically defined, is being eclipsed. Is it possible that Web interfaces and data disintermediation for legacy applications will be enough? Is it possible that exposing the old applications, and reducing costs of IT support via consolidation and modernization is enough?
In short, is the path of least resistance to business transformation one that necessarily requires a fording of the SOA stream? Or is there a shorter, dry path that goes directly to Web oriented architecture? Is SOA therefore the impediment or empowerment to transformation on the right scale and at Internet time?
Is it better to seek business transformation, or perhaps to seek just enough transformation that creates better services for my employees and customers, ones that rely on the Web as much as possible? And if you don't need to go full-bore SOA on the infrastructure side to enjoy lower cost with better extension of application logic and data value, they why do it? Or why do it first?
And if you can build new applications of code, not components, and the interactions are all loosely coupled from start to finish, and the Web GUIs are what become automated -- rather than the middleware -- then doesn't that make sense, too?
What seems most important from the legacy IT installations is better access, control and extension of the application-specific data. And we can do that without full-bore SOA. And we can access that data from these WOA applications.
Maybe we don't really need a unifying theory of datacenter assets and resources after all. Maybe we can recognize that particle physics is particle physics and gravity is gravity, to use a matter-of-fact analogy. Why boil the ocean, when you can fry up a few fish and serve them up fast to the highest bidders?
I'll be seeking answers to these questions next week at the IBM Impact WebSphere conference in Las Vegas. The same questions will no doubt be on a lot of minds, and as well for those evaluating Oracle, BEA, SAP, HP, and Microsoft when it comes to SOA and WOA values.
I'm seeing a lot of good productivity being created from both legacy modernization and new Web development-and-deployment efficiencies -- and they are by no means mutually exclusive. Indeed, data integration advances and Web oriented architecture together may be the real SOA adoption path.
So let's keep an eye on how social media and networks enable workers inside of companies and users outside of companies to relate in ways that help them find what they want and what they need -- and to with quite impressive ease combine and unite as teams -- for fun and productivity. Business process efficiency may come from business-oriented social networks than from business analysts-driven services repositories and governance-enabled policies engines.
And composite applications may come from rapid Ruby development and Agile team practices -- perhaps deployed lickety-split to a public or private cloud -- than from a BPEL orchestration approach.
Services reuse may not matter as much as the kinds of use that drives constant iterative improvement on Web-facing online widgets and mashups. The real goal is to get work done and to make business and consumer services quickly and dependably available to the online and physical markets. For these real results, is SOA an impediment or empowerment?
SOA's aims have been worthy -- light-weight development, fleet compositing of services and applications, easily customizable processes, flexibly deployment options, reduced total costs, and legacy assets extensions. But there does seem to be more than one way to skin a cat.

Service Oriented Architecture (SOA) consultant and author Dave Linthicum has taken over as CEO at data services provider StrikeIron, just six months after Linthicum sold his consulting firm to and became a managing partner of SOA analysis firm ZapThink.
On April 2, Linthicum was identified as CEO of StrikeIron in an article on SysCon.com, "RIA, SOA & Web 2.0 Mashups - Mash What?" StrikeIron is also conducting analyst briefings this week on Linthicum's new role as new CEO, though no news releases have apparently been issued.
Linthicum will continue as a ZapThink contributor and associate, said Ron Schmelzer, ZapThink managing partner and senior analyst. "Actually, it's a very positive thing happening.
"Technically, Dave Linthicum is still a ZapThink contributor and associate. We had negotiated something as part of our acquisition that would allow him to also serve as a CEO if an opportunity so presented itself. And one did. So, we're all still one big happy family,"said Schmelzer.
“I’m still a ZapThinker at heart, however I also have passion around what StrikeIron is doing and wanted to be a part of it,” said Linthicum. “I loved working with/at ZapThink. I will still be a contributor, adviser, and friend of ZapThink.”
Linthicum has offered his expertise on Enterprise Application Integration (EAI), SOA and Web 2.0 through speaking, consulting, advisory services, and prolific blogging and writing. In September, ZapThink acquired The Linthicum Group, making its founder a major partner in the SOA services firm.
Before forming Linthicum Group, he had been the CEO of BRIDGEWERX, former CTO of Mercator Software, and has held key technology management roles with a number of organizations including CTO of SAGA Software, Mobil Oil, EDS, AT&T, and Ernst and Young.

The writing is clearly on the wall. The iPhone will grow into a significant enterprise end-point role, and OS X Macs will quickly advance beyond the now 20 percent share (estimated) of the total non-enterprise fat client compute device market. This is all but done.
Problem is that Apple is winning in the old war -- the PC vs the Mac, and the smartphone vs the mobile Internet device (MID) battles. The larger, more long-term opportunity has moved upward and outward into the realm of the services cloud. Becoming the funnel through which to acquire, access and pay for the cloud-spewing services is the new war. Client hardware isn't going to matter that much very soon, and will likely become free.
Just as Google Docs gains an offline capability, more of what will make people and workers productive will be what they get as pure services from cloud-based hosts. The next war is the cloud war, and the battles will be fought around software as a service, desktop as a service, integration as a service, infrastructure as a service, platform as a service, development as a service, content management as a service, and so on.
The new money will made through a combination of access subscriptions, direct payments for digital and media objects downloads, advertising, revenue sharing from online retail transactions, and B2B lead generation motifs.
Apple is in a good position to grab a portion of these revenues, but only a portion. Google is in a better position. And the Microsoft-Yahoo conglomeration may be in the very best position, but nothing is set in stone.
Microsoft seems to gets this. Because it does not have a client hardware business (mice and keyboards not withstanding) it can race to the next big thing on software, better than, say, Dell. Microsoft has all but given up on the the fat PC business for its future growth. Fat PC clients are a maintenance business now for Redmond.
As long as the packets make it down to the end point and get rendered, Microsoft can find new ways to grow, which are all about the cloud, integrated services, single sign on, virtualized CALs, and advertising. They call it software plus services, but it's all about the services and the dollars.
Microsoft may lose the installed Office business cash cow, but it can gain far more variety of services ... with ultimately a larger addressable market. Microsoft has figured out, thanks to Google, that the Internet business is bigger than the PC business. And these services may well represent a 50-year business trend line, instead of the fat client 20-year business that is now topping out.
Apple surely gets this too, and it's already engaged accordingly. So let me make some predictions. Apple will only have a handful more of meaningful product generations on client-side hardware. Yep, that's right, the iPhone and the Air are the beginning of the end, just because there's not too much more innovation needed down there in the hardware space. Please just add more flash memory capacity and build in the multi-protocol broadband network connectivity to the chip, and we can wrap it all up.
There's only about two to three more years left in the client hardware innovation business before the end-points go pure commodity, even with Apple's intellectual property. The hardware becomes a basic catcher's mitt for the packets, a single chipset that grabs the several important signals and processes them into a basic Web UI and supports the runtime, virtualized most likely. I, for one, don't want to see native iPhone apps; just use the browser and great UI.
But the software layer on top of the hardware, now that's a different story. And it's not a Windows domination segue guarantee, no sir. Too much baggage to support. Microsoft needs a standalone lightweight client story, and neither Vista nor CE is it. Microsoft needs to practically start from scratch on the client software of the future.
And so Apple needs to exploit this "window" of opportunity, and to take iTunes to a much larger role: The new lightweight operating system for the modern cloud services and commerce end-point. This new layer can very quickly emerge from iTunes-as-cash register for music version -- and grow into the everything else under the sun as a service (and cash register) layer.
And that's why Safari on Windows is a massively important campaign for Apple. For Apple to be a player in the cloud-based future, it must parley its iTunes hegemony into a Safari critical mass -- and that has to come at the expense of Internet Explorer and (sorry to say) Firefox.
Next, Apple will then need to munge together Safari and iTunes into a uber client layer for cloud computing-generated services reception and payments -- on mobile, PC, MID, anything that can catch the packets and support an iTunes browser. This is the funnel play, and Apple probably can do it better than anyone.
And so then comes the big question. Will Apple use this new software client model to make the services tie-in closed, open, or how open? Will Apple try and do on the Safari/iTunes client model what Microsoft has so far failed to with Windows? Will Google keep Apple open enough on all of this?
Microsoft, with the massive Yahoo audience it may soon own, will try and hold on to the client software chokepoint -- even as Apple makes a mad dash for it. This is the new war, and it has little to do with the difference between a Mac and a PC. It about both and how they access the clouds.
I suspect an Apple-Google partnership could outfox the Microsoft-Yahoo hairball, and that the Safari-iTunes-Android trifecta looks pretty interesting as the new client platform. What do you think?

The existing SpringWebServices (SWS) within Spring supports Web services through the contract-first model, by which users start with XML schema and WSDL definitions of their service. WSF/Spring 1.0 adds code-first support, by which users can start with existing Spring beans and offer them as Web services with a simple Spring configuration.
Paul Freemantle, co-founder and VP of sales at WSO2, the open-source SOA company located in Mountain View, Calif., and Sri Lanka, explains why this new feature is important in his personal blog:
- Support for the WS*- stack, including WS-Addressing, WS-Policy WS-Security, WS-SecurityPolicy, WS-ReliableMessaging, WS-Eventing, and SOAP Message Transmission Optimization Mechanism (MTOM).
- Inversion of Control (IOC) container support enabling Spring services to be exposed through an IOC container, as well as support for editing the Axis2 booting configuration through the IOC container.
- Automated WSDL generation via the Axis2/Java code generation tool.
- Querying service support.
- Method exclusion in Spring beans, allowing developers to have fine-grained control over which methods are exposed as Web service operations.
WSF/Spring 1.0 is available for download today, and carries no software licensing or subscription fees. Support is available from the WSO2 site.
