Windows VPS plans were once very rare, but are increasing in popularity. There are several platforms available for consumers, including Virtuozzo and Plesk. Since Windows is a commercial OS, vendors must factor in the operating system cost into their pricing. This results in higher monthly costs for Windows VPS plans, as opposed to freely available operating systems such as Linux. Despite the higher cost, many customers want the power of a VPS, but have already invested in Windows-based hosting and applications. For them, these plans are worth the small added monthly cost
One of the most popular platforms for the VPSes is Virtuozzo. This product is made by SW-SOFT, which has a good reputation and has been in the marketplace for several years. Their Linux-based VPSes have been well regarded in the marketplace, and now their Windows offering is rapidly gaining popularity. Most vendors will provide Windows Server 2003 in their Virtuozzo plans.
