An interesting article on Windows 8 Server.
Why Windows 8 server is a game-changer
More than just a few tweaks…
Windows Server has always been the choice of businesses for system administration and file storage. The only significant competitive advantage that Linux/Unix had was its better scripting interface. It lost this with the introduction of Powershell.
The author says that Windows 8 Server exposes everything though Powershell and also makes previously high-end features like High Availability (HA) very easy.
This is all sensible and very necessary if Windows is to compete against Amazon EC2 and other cloud vendors which offer inexpensive but still rather difficult to configure Linux-based solutions.
