The City of Cape Town, South Africa's second most populous city, maintains two data centers that are used by its departments. In 2011, 150 of the city's 350 physical servers were reaching the end of their lives, posing a risk to the delivery of city services. The city considered whether to maintain its old servers, replace them with new ones or implement a private cloud solution that used virtualization technology. Its decision rested on the adoption of a robust, integrated solution that was cost effective, efficient, highly automated and highly available. The city turned to Microsoft, developed a private cloud solution using Microsoft Windows Server 2008 R2 Hyper-V and Microsoft System Center and consolidated 150 servers into six virtualized servers.
