The software giant said last week that an early "" version of a new communications system being built into Windows, called Indigo, will be in software developers' hands in March.
To most people, the Indigo software will be invisible, simply a recast set of "plumbing" that only software programmers will interact with. But if Indigo lives up to Microsoft's ambitions, its impact will be great, according to industry executives and analysts.
Microsoft will release an early version of its Indigo communications system, designed to simplify connecting Windows to other systems via Web services protocols.
Indigo is a stepped-up attempt to tap into big-ticket integration projects--and Microsoft's oversight of Windows and its close ties to development tools gives it an edge.
"It's been a while in coming, but when it eventually comes on market, Indigo will be an innovative and competitive product," said Mike Gilpin, an analyst at Forrester Research.
Because Indigo is being plugged right into Windows, Microsoft will have a well-integrated product, compared with competitors in the Java server software camp, Gilpin said.
Typically, communications software that integrates various systems runs on high-powered servers. Indigo will be much more pervasive: it will be available--for free--on server and desktop versions of Windows, including Windows XP, Windows Server 2003 and the forthcoming Longhorn edition of Windows.
"One of the common misconceptions is that these are server technologies. Fundamentally, the vision Microsoft has for distributing computing is not just forcing everything through a server or through the Web," said John Montgomery, director of marketing for Microsoft's product division. "You need the technology on the desktop as much as the server."
Microsoft also has the advantage of having legions of developers already trained on Visual Studio, its flagship development tool. Indigo introduces a programming model designed to greatly simplify the creation of distributed applications.
"At the developer level, it's still a nightmare choosing which communications transport to use," said Tim Huckaby, CEO of
