Windows Server 2012 runs only on x64 processors. Unlike its
predecessor, Windows Server 2012 does not support Itanium.
Upgrades from Windows Server 2008 and Windows Server 2008 R2 are
supported, although upgrades from prior releases are not.
Reviews of Windows Server 2012 have been generally positive. Simon Bisson of ZDNet described it as "ready for the datacenter, today," while Tim Anderson of The Register said that "The move towards
greater modularity, stronger automation and improved virtualisation
makes perfect sense in a world of public and private clouds" but
remarked that "That said, the capability of Windows to deliver
obscure and time-consuming errors is unchanged" and concluded that
"Nevertheless, this is a strong upgrade overall."
InfoWorld noted that Server 2012's use of Windows 8's panned "Metro" user
interface was countered by Microsoft's increasing emphasis on the
Server Core mode, which had been "fleshed out with new depth and
ease-of-use features" and increased use of the "practically
mandatory" PowerShell. However, Michael Otey of Windows IT Pro expressed dislike with the
new Metro interface and the lack of ability to use the older
desktop interface alone, saying that most users of Windows Server
manage their servers using the graphical user interface rather than
PowerShell. The Australian construction company Kennards found the OS stable.
Paul Ferrill wrote that "Windows Server 2012 Essentials provides
all the pieces necessary to provide centralized file storage,
client backups, and remote access," but Tim Anderson contended that "Many businesses that are using
SBS2011 and earlier will want to stick with what they have", citing
the absence of Exchange, the lack of ability to synchronize with
Active Directory Federation Services and the 25-user limit, while Paul Thurott wrote "you should choose Foundation only if you
have at least some in-company IT staff and/or are comfortable
outsourcing management to a Microsoft partner or solution provider"
and "Essentials is, in my mind, ideal for any modern startup of
just a few people."
