"Microsoft is committed to delivering a broad set of enterprise-ready
products and services that build on the existing capabilities and skill sets
of service providers like Rackspace," said John Zanni, general manager of
Worldwide Hosting for the Communications Sector at Microsoft Corp. "As a long
time partner of one of the industry's top cloud hosting providers, we are
excited that Rackspace's Cloud Servers for Windows offering has exited beta
and is now available to the thousands of businesses that have built their
infrastructure around Microsoft Windows and Microsoft .NET technologies."

SpaBooker, a SaaS scheduling and point-of-sale (POS) application
specifically designed for the spa, salon and wellness industry, utilizes
Rackspace's hybrid solution by using managed dedicated servers
(www.rackspace.co.uk/managed-hosting/hosting-solutions/dedicated-serve
rs/) in addition to their cloud computing solution, Cloud Servers for
Windows. Daniel Lizio-Katzen, SpaBooker Managing Director, states: "When we
set out to look for a cloud computing solution, we didn't hesitate to look at
Rackspace Cloud first as we've been very pleased with the high level of
support received from their managed dedicated servers. Rackspace Cloud
Servers has been the ideal solution to separate our actual application from
our public facing website. We currently have our entire staging environment
running on the Cloud Servers for Windows Beta and the overall ease of use has
been phenomenal. The cost savings compared to traditional dedicated hosting
are also substantial."

"We're constantly looking for ways to increase the flexibility and choice
customers can find with Rackspace Hosting (
www.rackspace.co.uk/rackspace-home/). After several months of
successful beta testing with hundreds of customers, we're excited to remove
the beta label and offer Cloud Servers for Windows to the market," said Pat
Matthews, VP and GM of Cloud Hosting, Rackspace. "We believe this product
will be attractive to new Rackspace customers as well as those we are already
serving."

The service provides a full suite of features supported by the industry's
leading Service Level Agreement (SLA) and Rackspace's hallmark customer
service, Fanatical Support. Pricing currently begins at $0.08 an hour for 1GB
RAM and 40GB disk.
