Download the authoritative guide: Cloud Computing 2019: Using the Cloud for Competitive Advantage
Big companies across all sectors, we're told, are building SOA infrastructure. Business analysts and tech departments are eagerly putting aside their historic enmity to discuss upcoming SOA projects.
After all (and this part is true), SOA offers key competitive advantages. Over the years, companies have built computing infrastructures that combine a patchwork of environments, from Java to .NET to Sun Solaris. SOAs promise is that it can integrate these disparate worlds to create unified interfaces (called services) for employees and customers.
Thats a big deal. Its reasonable to believe that companies would be rushing to implement SOA.
To create excitement, vendors issued a profusion of press releases and held copious workshops with free donuts. In response, they got a lot of polite nods. Vendors made a big deal out of this, but nothing much was happening out in the market at that point, Hedin notes.
And not all that much has continued to happen. I think in the beginning, back in 2004 and 2005, they were a little disappointed that it was slow. And in 2006, they were hoping, Oh yeah, this is a big year for SOA. And it really didnt pan out to be a big year.
While she hastens to add that things are starting to progress, its not as if SOA is on the lips of every IT decision maker. Based on a 2006 survey by IDC, only 23 percent of companies have a SOA project in production, with another 18 percent having one in pilot stage. Thats a tentative embrace of SOA, given that 22 percent either dont know if theyll invest or have no plans to invest.
More positively, 37 percent plan on investing in the next 1-2 years. (Although as Hedin notes, "Thinking about it is different than doing it.)
Still, the land rush is yet to happen. I think the vendors expected a much faster growth rate in terms of adoption, she says.

Seeing Their Neighbor Do It
Perhaps the most convincing factor prompting companies to begin dipping a toe in the SOA waters is hearing that other companies are doing so.
Now in 2007, there are a healthy handful of success stories. As enterprises started to hear from their peers that theyre adopting SOA, and seeing demonstrated cases with benefits then it obviously started to become more of a compelling issue to look at, Hedin says.
Confidence levels are starting to creep up. The combination of vendors, showing cases, and the media, publishing cases, is started to help, she says. Companies are starting to think, Oh, this is actually happening, this is a real thing Maybe we should be on board here, and at least learn about it, at least find out what the benefits are to our particular situation.
Finally Calling Vendors
As if SOA vendors werent frustrated enough in their desire to sell this new technology, some of the early adopters did their SOA projects in-house. They hired no outside help. Many of the early adopters wanted to tinker and play without having third party input (and without third party expense).
These early pioneers launched modest projects. They started very small. Very concrete, and tangible, and fairly limited types of projects, Hedin says. Then they moved from one small project to another project."
But things are now changing, she says.
Shes hearing from companies that began SOA initiatives years ago, on their own, like ADP, Olsen Energy, the City of Chicago, and Amtrak. And as they started to feel more and more comfortable, and learning the pros and cons, building their own skill set around SOA, they are now starting to bring in vendors to help them expand their initiative into other departments.
Theyre opening their pocketbooks to vendors because theyre trying to roll out SOA to a larger group of users within the enterprise. These more ambitious rollouts require, among other things, a well-articulated business case a specialty of vendors.
The clients have laid a foundation, but now they need additional help to roll this out and do more complex stuff.
Okay, Then SOA is Finally Ready To Take Off, Right?
Given that SOA is starting to see some momentum in adoption, will 2007 be The Year of SOA?
It is a little difficult because we keep on saying that every year, Hedin says, laughing. You get a little cynical about saying that. We said that in 2005, we said that in 2006, are we going to say that again in 2007?
The problem is, theres nothing simple about SOA.
In its attempt to simplify things, it actually makes them more complex, it creates more complexity, Hedin says. Its sort of an oxymoron in a way. As [companies] are rolling out SOA, there are so many organizational change issues that need to be addressed.
Apart from the sheer technical complexity, full-scale deployment of SOA requires deep interdepartmental shifts. No wonder its slow going.
The IT departments relationship with the business side also has to change. The IT side has to understand the business side finally. They need to understand what the requirements are so that the IT department can create these applications and services to really support the business.
So How Long Is It Really Going to Take?
So, okay, SOA is just starting to gain real acceptance in the enterprise in 2007. Does that mean that by, say, 2009, it will be really taking over?
Its going to take longer than that, Hedin says. Were talking about a very, very long journey here. There are going to be some enterprises who have SOA throughout the organization. There will only be a handful, a few of them, I think well probably count them on our hands.
For example, Ive been talking to Washington mutual, and there are SOA projects here and there, but you cant say they are enterprise-wide yet. They have a little project over in that department, a little project over in that department. And they have different vendors helping them with that. But is it enterprise-wide yet? No, and it will probably take a number of years.
