Long list of updates answer criticisms and throw punches at virtualization, cloud foes
In Windows Server 2012 R2 and Windows 8.1, Microsoft has released a combination of operating system updates that we find very compelling. Microsoft has joined much of the rest of the industry in annual release roll-ups with feature additions, and this time, they listened to the critics. More interesting are the one-upmanship features targeted directly at its virtualization and cloud competition. Some were stunning, despite a few strange and perhaps anecdotal basic problems that we found.
Windows 8.1 is the answer to loud and vociferous complaints regarding radical changes to the user interface found in Windows 8, and is currently a free upgrade for 8.0 users. What’s apparent in 8.1 is that Microsoft is committing strong changes to the tablet and touch user interface in its Surface devices first, in order to compete with Apple and Android. If 8.0 didn’t convince you, then 8.1 is a shot across the bows of those believing that desktops and notebooks rule IT.
Microsoft has targeted Windows 2012 R2 directly at data center and service provider use, along with baseline connectivity to Azure Cloud services and third party Azure services providers. Microsoft’s other targets are Oracle and VMware.
Microsoft offers a free add-in for Windows 2012 R2 of its Azure Pack to connect cloudlike constructs, and anchors it with various free and paid appliance services that battle competing IaaS/SaaS providers and other MSP/cloud competitors. Through gritted teeth, Microsoft is also supporting specific instances of commonly used Linux distros as manageable guests within the Hyper-V and Azure infrastructure.
By contrast to the heavy work done in 2012 R2, Windows 8.1 is a far lighter weight set of changes, and largely addresses criticisms of Windows 8.0.
Authentication and access enabling technologies are important in a BYOD universe. Many Windows users find Apple’s iTunes to be difficult to use as an authentication system under Windows, with frequent unthreaded new releases. Microsoft has responded with a unified identity method enhancement of its Windows Intune ecosystem and Active Directory-poised authentication methods.
The Good News
What we liked about Windows 2012 R2 is that it’s generally easier to use than Windows 2012 — fewer sharp edges — and 2012 R2 contains stronger networking, storage, and hypervisor skills, we found in testing. Microsoft has also made it almost fiendishly consistent and easy to join Windows 2012 R2 to Azure Clouds — and it’s practical if organizations have fast Internet pipes.
Both new Windows releases are highly targeting enterprise customers, although a Windows 2012 R2 Server Essentials Edition (traditionally limited to 25 or fewer users) is available, and not reviewed here. The Essentials Edition must live within three total VMs, which limits possible users, unless something unforeseen and magical happens in hardware.
If organizations want a control plane, Microsoft attaches System Center 2012 R2 releases of Ops Manager, Virtual Machine Manager, and Configuration Manager that are deeply intertwined into the depths of Server 2012 R2 and Hyper-V.
During briefings with Microsoft, we had to constantly disambiguate what was a Server or Azure or System Center feature as Microsoft blends them together. In doing so, Microsoft wants its value proposition to be considered as a mixture of the three, but this review focuses on only the Server, Windows 8.1, and the free connection to Azure Pack.
For its part, Windows 8.1 solves the silliness of bringing back the familiar Desktop, along with ways to access applications in ancient and hallowed ways. While the Windows Start menu is gone (available from third parties if desired), there’s a method to show apps selections onscreen easily. Windows 8.1 is also faster than 8.0 — this additional speed makes the most impact when it comes to video drivers and the Server Message Block (SMB3) communications transport protocol.
SMB3 speed isn’t proprietary to Windows as SAMBA 4.1 — the open source SMB emulator that can be used by Mac OS, Linux, BSD, and other non-Windows operating systems, is now compatible with SMB3. However, SAN and NAS devices may not support SMB3 until vendors can get caught up.
Much attention in Windows 8.1 surrounds features that will be found in tablets, like Microsoft’s own Surface Pro. Multi-touch object manipulation and attention towards touch and tethered keyboard combinations abounds. We tested 8.1 and found an enormous variety of keyboard manipulations and touch motions that produced interesting effects.

2012 R2 and Hyper-V
Windows 2012 R2 contains a number of storage options poised towards Hyper-V, but we found that R2 can probably be booted from a wristwatch and store data on our sneakers — if we format them NTFS. We successfully booted local hardware (you may need BIOS updates), iSCSI, and virtual network storage. Many will be booting VMs, and Microsoft has made this especially simple under Hyper-V V3.
Hyper-V V3 has received much work, and Microsoft considers it a “Generation 2” hypervisor VM-hosting platform that delivers a higher degree of para-virtualization and cuts away much hardware layer specific driver emulation, although other OS versions/distros of hosted VMs can still find connection points.
Hyper-V V3 and its Windows 2012 VMs also boot UEFI, rather than traditional memory-location-specific BIOS. This gave us a few fits, but works. There is the capacity to move virtual machines from host to host using compression, and where compatible hardware is available to support it, very fast transports — 10Gigabit Ethernet, Infiniband, and other faster-than-10G Ethernet connections. The high-speed connections are crucial to VM movements among hosts in hypervisor fabrics.
We tested Microsoft’s virtual network switching component, and found it easy to manipulate, although we disconnected several remote hosts by making inept choices. The instructions weren’t clear to us, and we were able to crater the communications of two of our test servers with ease. The drive to our network operations center is a long one.
The SDNs inside Hyper-V V3 are more easily manipulated by System Center 2012. Microsoft includes IP Address Management/IPAM in Hyper-V, and as VMware has found, is heaven-sent for those with genuine desires to form virtualization platforms where VMs can be easily transported from host to host for either performance or isolation within a defined fabric/VM farm.
