The trend makes sense, technology veterans say. On-demand is the next progression from the client-server era of computing to a more distributed model of offering utility-like data center computing services to corporate customers.
The positioning for on-demand computing services, utility-style, also reflects the IT industry's profit margin shift to higher-value, value-added technology such as software and services.
For enterprise software providers such as Computer Associates and JD Edwards, as well as application service providers such as Salesforce.com, the answer is yes.
Gone are the days when software providers would "back up a truck to the company's front door" and "dump as much software as possible," said Louis Blatt, chief technology strategist for enterprise software company Computer Associates, and expect a huge up-front license fee from a customer.
Blatt said many of CA's products are being "granularized," or comprised of separate components, which also reflects the company's adoption of Web services protocols for open standards that are also part of a technology shift to provide on-demand computing.
CA recently unveiled its own foray into on-demand with its Unicenter line of products, which it calls "Managing On-demand Computing."
The latest Unicenter products consist of modules that are designed to help customers "dial-in" as much network management resources as they need, instead of deploying extensive overhauls of IT structures.
The idea is to offer integrated applications that help clients manage heterogeneous infrastructure, provide self-management/self-healing capabilities within the applications, and create service-oriented architecture that radically simplifies operations for IT staff.
Perhaps the biggest change in CA's on-demand offering is its flexible licensing model, which CA calls "FlexSelect Licensing."
Blatt said the program is fundamental to delivering the company's products as a service. And it means that, as software companies increasingly offer smaller software packages, revenue recognition models are changing as well.
Offering software applications "by the drink" now means that, instead of one big purchase up front of software licenses, revenue is being recognized on a weighted basis, in scale to how much a customer is using each month.
Les Wyatt, chief marketing officer of enterprise supply chain software company JD Edwards, said the company began offering up its various supply chain management products in smaller packages, or modules, during the mid-1990s.
"The difference is how we've packaged our software so we give the customer choices," whether that entails application service provider models, or pricing software usage by the seat or users, said Wyatt.
Historically, for software companies, licensing their product code to customers has been the lion's share of their revenues, followed by maintenance or user fees for the life of the license.
The value of the product was in licensing huge chunks of code. Additional users were a smaller portion of total revenue. But amid the trend toward delivering computing services on-demand, that model has now flipped, with the user fees gaining in importance.
"Over the last few years, we've moved very strongly to a user-based pricing model," said Wyatt. In JD Edwards' case, that might translate to a customer that decides to implement the company's invoice-processing software, or sales force automation tools for its sales staff, and perhaps order up some chunks of distribution management applications.
"That's one way we've packaged our pricing so it scales. Once you buy a user (license), that user can pretty much use any application" the company is running.
