Microsoft has said that getting third-party developers to build their own applications on top of its Web services will help push its Windows Live initiative over the top. So far, however, despite some interesting applications mashups, the Live community has been a little murky on the details.

Microsoft’s MIX07 developers and designers conference, coming up at the end of April in Las Vegas, promises to be the venue where the company reveals more of its plans to make Windows Live into a bona fide “platform” for third-party developers.
Company officials have hinted since last year that they are working to create such a unified developers platform for Live services. But they have been purposely vague about how it will all fit together. Instead, they have repeatedly said “wait for MIX07.”

However, Adam Sohn, director of worldwide sales and marketing in Microsoft’s online services group, recently agreed to talk a little about what’s coming.

First up, the company is working to present a more cohesive architecture than it has previously for its emerging Live Services businesses — something that many industry observers have been concerned about.

“The fragmentation of the Web is a major source of dissatisfaction today…our vision is [to provide] a one stop shop.” Ultimately, the idea is to deliver a framework built on top of the diverse Windows Live APIs.

That won’t happen all at once.

“In phase one, [we’re defining] how do you look at all of the services and how do you put together an architecture for that?” said Sohn.

With the emerging framework, Sohn added, APIs fall into two fairly distinct categories — infrastructure and applications.

So what constitutes the infrastructure part of the Live services and APIs? That would be identity, relationships, advertising, domains, and storage. Applications services, on the other hand, include instant messaging, search, Spaces, mail/calendar, expo (classifieds) and mapping.

Sohn also said that, although it has been reported that use of the adCenter service will be mandatory in the future, no decision has been taken yet. “We’re not at a point to say what’s mandatory and what’s not.”

Despite officials’ reticence to provide much detail, the company has made some obvious preliminary moves to fine tune its Live developers platform message.

For instance, in late January, Microsoft announced a Windows Live SDK of sorts, even though so far that only amounts to a Web page with links to the individual Web services SDKs and their concomitant Windows Live APIs. It does at least pay lip service to providing a cohesive architecture for developers.

Much has been written and said since Microsoft announced its Live initiative in November 2005. Internally, Chairman Bill Gates and Chief software architect Ray Ozzie have championed the idea of an advertising driven model for providing software as a service.

Currently, some of the pieces have been delivered, at least in version 1 forms. Others, such as the Windows Live Contacts Control, which Sohn describes as providing access to “probably the largest social network on the planet,” are still in beta test.

In another recent update, in late January, Microsoft released the Live Search SDK (see accompanying story).

Meanwhile, as Microsoft’s minions are working on providing the software needed to make Windows Live work, the company is also dashing to create enough server space to provide Live services on a truly global basis. That is, Microsoft is investing heavily in data centers to support all of those users and their services.

“This is a scale game,” said Sohn. “You want everyone to plug in so that you get really meaningful scale [and in order to do that] we have to have huge geo-scaled operations.”

To that end, in January, Microsoft said it will invest $550 million to build a 470,000 square foot data center in San Antonio, Texas, to support its services operations. The 40 acre site will feature two buildings housing tens of thousands of servers and take a year and a half to two years to complete, the company said.

A year ago, the company purchased 75 acres in Quincy in central Washington, primarily for its proximity to Grand Coulee Dam’s electrical output. That site, where construction began last May, could eventually provide an additional 1.4 million square feet of data center space, according to Lawrenceville, New Jersey-based news and analysis site Data Center Knowledge.

In addition, last spring Microsoft hired Steve Berkowitz, who was then CEO of rival search firm Ask.com (previously Ask Jeeves), to be the senior vice president in charge of its Live efforts. He is widely viewed to have turned around Ask.com’s downward trajectory, making it the second largest “pure search” site on the Web, according to his official Microsoft biography.
