This is a world first, according to Microsoft, as the software is the only truly open source web application to achieve certification on the Windows platform. SilverStripe got its big international break when its software was used for the Democrat's National Convention website as Barak Obama made his run at the White House. More recently, among many other projects, Silverstripe has been involved with the government's Open Data project. “We are very excited about receiving the certification, as it validates everything we have been working toward – ease of use and added value for our customers, along with faster deployment times, as well as confirming the robustness and reliability of our software,” said Sigurd Magnusson, co-founder and business relationship manager of SilverStripe. “At least half of SilverStripe’s customers manage predominantly Windows Server IT environments. These customers are now able to confidently deploy our software on the Microsoft platform. The addition of Internet Information Services (IIS) and SQL Server support for SilverStripe CMS opens up a diverse new market, and we are confident that greater interoperability with the Windows platform will contribute to our further success in the years ahead.” Certification for Windows Server is achieved through an independently audited process that has extensive and strict criteria. In addition to being the only open source web application to attain this, the other unique element of the certification is the SilverStripe application was written in PHP rather than the .NET format. “As an active participant in the web and open source communities, Microsoft welcomed the opportunity to work with the SilverStripe team to further develop our relationship with open source developers,” says Andrew Gordon, Platform Strategy Manager for Microsoft New Zealand. “We would like to congratulate SilverStripe on its well-deserved win at the New Zealand Open Source awards last week and look forward to continuing to work with the team to further create a mutually beneficial relationship.” In the time SilverStripe and Microsoft have been working together there have been more than 60,000 downloads of the SilverStripe CMS from Microsoft's website.
