Citrix will buy real-time provisioning technology company Ardence for an undisclosed sum.

The purchase will add real-time, on-demand provisioning of desktops, server images and service oriented architecture objects to its application services.

The deal should be completed early next year and Citrix said it expects the acquisition to add $15 million to $18 million in revenue over the course of the year.

Business customers will be able to use Ardence's technology in a number of ways, providing more options for delivering applications and using resources, Citrix said. Ardence's provisioning capabilities will allow sysadmins to add new servers to a Citrix server farm faster than previously and also provide dynamic configuration of servers in a data centre.

Ardence's technology will also allow users of Citrix's NetScaler line to change the amount of storage or CPU capacity available to Web applications. It should also cut down on the complexity involved with the real-time roll out of software and enable IT workers to remotely boot desktops, laptops, servers and blades.

Ardence has 100 employees and over 3,000 customers. It will continue to be based in Massachusetts but become part of Citrix's Management Systems Group.
