Is Windows Azure cheaper than Windows Server?
Because these are different products – one is an operating system, the other is a cloud service – the two products cannot be easily compared based on price. Windows Server is purchased via a software license. In contrast, Windows Azure is a cloud service whose pricing reflects costs associated with server hardware, software, network bandwidth, storage and the management of the hardware running Windows Azure. We have designed each offering to offer customers the flexibility to choose the platform and business model that best suits their needs.
