In the early days of client/server adoption in the 1990s there were lots of articles lamenting the fact the client/server wasn’t living up to its promise. It was just another theory that didn’t really work all that well in practice.

But after a few years client/server was just the way application development was being done. It wasn’t a theory any more, and too some extent it ceased to be a hot topic for debate. It was old hat.

New technologies including XML, Web services and finally SOA became the hot topics. Of course, as a Gartner Inc. analyst pointed out in a talk a few years ago, SOA pretty much began in the mid-1990s as an extension of client/server.

“Customers were doing SOA then although they weren’t calling it that,” Massimo Pezzini, vice president and distinguished analyst Gartner Inc., said in a 2006 talk. They tended to use the terms of the 1990s for their projects, calling them client/server. Pezzini said that is the secret few SOA gurus want to let out of the bag: SOA is an update of classic client/server.

In a recent article about the problems with SOA adoption, Ron Schmelzer, senior analyst with ZapThink LLC., also credits Gartner with the transformation of client/server into SOA in 1996.

So it seems client/server, which didn’t live up to its promise, has morphed into SOA, which isn’t living up to its promise. But lots of organizations did client/server even if they did it imperfectly, and it appears organizations are now doing SOA albeit imperfectly.

The nature of things humans do is that they are generally not perfect and almost always could be better. With the exception of 4.0 students, most of us got educated imperfectly. The interstate highway system in the U.S. is far from perfect but we’ve been getting around on it for decades. City planning, which Schmelzer says may be the best analogy to SOA because both are always works in progress, does not produce perfect cities. But it could be argued that city planners in many cases help design more liveable and workable cities.

Interviews with CTOs, architects and developers who are actually doing SOA indicates that progress is being made despite the lack of perfection.

In a user story this week Manny Montejano, CTO at Cars.com explained how he is achieving the elusive SOA goal of getting business executives and managers to drive SOA initiatives. But at the same time, he pointed out that his SOA implementation is only about 30 percent of the way to achieving its ultimate goals. And there have been bumps in the road but he views them not as failures but as learning experiences.

 ”I’m not saying we’ve done everything perfectly every single time from the get-go, which is where our lessons come from,” Montejano said. “We’ve learned lots of lessons specifically that this is a business initiative not an IT/technical initiative.” 

Most of the people who are actually doing SOA talk about it in turns of evolution, or to use Schmelzer’s city planning analogy, an on-going project that is always changing and evolving but is never complete.

Shibashis Mukherjee, lead enterprise architect at Con-Way Inc., the transportation company, actually began work in 1996 on what has become his company’s SOA implementation. 

In his account of more that a decade of working on the evolution, Mukherjee recalled: “We started with the component-based development methodology. At that time SOA wasn’t the big thing yet. We realized it would help us develop faster if we had reusable components to build applications. As our development process matured and SOA came into play, we figured out how to compose the services.”

Perhaps if SOA is viewed as a process we would be less impatient with its lack of perfection.

It’s amazing what happens you put a few thousand SOA users together. Suddenly you start to get a clearer picture of what service orientation can achieve at both the business and IT levels. That was probably the biggest takeaway for this attendee at IBM’s Impact 2008 conference last week: a lot of users are well down the road with this stuff. They’ve thought about it, put it into action and it’s responsible for a significant amount of mission critical business.

(The other revelation was that the B-52s have a keyboard player who looks like Jose Canseco, but I digress.)

Here’s a smattering of comments made by SOA users at the show:

John Roach, director of architecture and governance at Wal-Mart, focused on using SOA to help manage store stock levels and customer demand. “If SOA doesn’t trace back to you finding the right thing when you walk into our store at the time you need it, then it isn’t material for us,” he said.

Kumar Murugan, application development manager at pharmaceutical manufacturer and marketer Novo Nordisk, talked about centralized policy management and stressed the need to view all SOA projects as part of a continuous process improvement cycle. He also highlighted the importance of having a rigorous QA process.

“You need to do a system discovery for any new service,” he said. “You need to understand how reuse affects your existing services.”

Manny Montejano, CTO at Cars.com, called governance “the key thing we need to resolve to be successful” as his company deals with explosive growth.

“It’s important to say no sometimes,” he said. “You have to let people know that some things are going to be more trouble than they’re worth.”

Anne McDiarmid, CIO for Australian fabric and crafts retailer Spotlight, made a case against trying to solve every problem with a software purchase.

“I’ve got middleware hanging out of my middleware,” she said. “I don’t need more middleware.”

A whirlwind of corporate acquisitions in foreign countries has created an integration challenge for SEB, a Swedish banking and insurance company. Enterprise architect Anders Jader targeted data as a key element in bringing together this international banking conglomerate.

“We are now in a phase where we need to transform everything into one data model and then be able to use that data as a service,” he said.

Tony John, domain lead architect at Allstate Insurance, echoed the importance of data in all things service-oriented, stating “we need more data analysts and data architects.” He noted that the bulk of a $30 million mainframe-to-SAP project “was spent on understanding the data.”

John also made the case that technologists have to understand the business they work for, not just how their niche of IT functions.

“No matter what machine or network it goes through, it’s still a group of people doing some business activity,” he said.

For the past two years, we at SearchSOA.com have been told regularly by our members (numbering 450,000+ these days), that you need help with governance. Apparently the mechanics of running an SOA is one of the biggest challenges users face.

That’s no surprise, the reuse, performance, management and ownership aspects of SOA are, literally, a sea change for a lot of IT organizations. This is business as unusual.

With that in mind, we’ve put together our Pragmatic SOA Governance Seminar, a free one-day event which covers the design time, runtime and business aspects of SOA governance. The material is geared toward key decisions makers in your IT organization - CTOs, enterprise architects and app dev managers. The seminar will go beyond theory and focus on actionable steps you can take to achieve SOA governance right now.

The dates and locations of the seminars are:

• February 21, San Jose, CA
• February 26, Reston, VA
• February 28, Mt. Laurel, NJ

Those interested in attending need to submit a registration form or call Lauren Nickerson at 781-657-1782.

One of the leading lights in the SOA community, Anne Thomas Manes, vice president and research director at Burton Group, will be presenting the main sessions. In addition there will be a user case study presented in each of the three cities: Transunion in San Jose, the Department of the Interior in Reston and Synovus Financial in Mt. Laurel. Each of these users has gone through the hard work of implementing an enterprise-wide SOA and will share their hands-on experiences about best and worst practices when it comes to SOA governance.

We’ve taken pains to make sure this seminar won’t be the standard boilerplate presentation of SOA governance with some vendors then saying all you need to do is buy Product X and your governance needs will be solved. These events will identify specific governance pain points and offer up sensible solutions. At SearchSOA.com we hold ourselves to a high standard. Just as we take pains to give you independent, in-depth of SOA-related news (instead of repackaged press releases), we’ve made sure that you can walk away from this seminar with a laundry list of SOA governance action items.
