Windows Server 2012 also offers replication of virtual machines asynchronously. Called Hyper-V Replica, the feature is ideal for replicating VMs from site to site over limited WAN links.
A new feature called Storage Spaces treats hundreds of disks as a single logical storage reservoir and ensures resiliency by backing up data on at least two physical disks. The feature sets aside a designated storage area -- called a space -- for a defined category of data within the entire available disk capacity -- called a pool.
Storage Spaces can allocate a space that is larger than the actual available physical capacity of the pool that the space is carved out of via thin provisioning. This keeps data from overflowing the space by freeing up capacity whenever files are deleted or an application decides that such capacity is no longer needed.
Windows Server 2012 also enables managing servers in groups and includes an automated tool to periodically check for proper server configuration.
System Center 2012
This management suite offers new tools to better handle closely related cloud environments and virtual data centers, and has expanded the products it can manage to include some of the virtual environments of rivals Citrix and VMware.
The platform includes broad support for managing smartphones based on Microsoft's phone OS, but also those from Apple and from a range of vendors that base their phones on Android.
The Virtual Machine Manager, Orchestration Manager and Operations Manager can combine to make management of virtual environments simpler. For instance, the management suite streamlines configuring virtual machines to pick up the function of others when they go down so help desk workers can perform the task without escalating.
In a practical sense, System Center can give developers the capability to create and tear down virtual machines for their test environments within parameters set by network executives.
One downside is that upgrading to System Center 2012 requires a lot of network prep as well as education to learn what other Microsoft products are required in order for the various modules to work.
Microsoft spent $1.2 billion this year to buy Yammer as a way to beef up social networking and collaboration in its SharePoint, Office, Dynamics CRM, Lync and Skype platforms.
When its integration is completed over the next few years Yammer will add tracking of conversation threads and enterprise search to these applications, aggregate news feeds, manage documents and unify user identities.
Yammer is already available with Microsoft's Office 365 cloud offering and will gradually permeate the company's other collaboration and productivity platforms, the company says.
With the purchase Microsoft has bought the tools it needs to set itself up well in support of new ways corporations do business using tools that end users have become familiar with via their use of consumer social networks.
Microsoft did itself proud this year disrupting the Nitol botnet with a combination of technical and legal innovation, as well as seizing servers belonging to the worst instances of the Zeus botnet.
