In-Depth Information
Desktop Virtualization Desktop virtualization provides you with a virtual machine on your
desktop, comparable to server virtualization. You run your complete operating system and
applications in a virtual machine so that your local physical machine just needs to run a very
basic operating system. An example of this form of virtualization is Microsoft Virtual PC.
Application Virtualization Application virtualization helps prevent conflicts between
applications on the same PC. Thus, it helps you to isolate the application running environ-
ment from the operating system installation requirements by creating application-specific
copies of all shared resources. It also helps reduce application-to-application incompatibil-
ity and testing needs. An example of an application virtualization tool is Microsoft Appli-
cation Virtualization (App-V).
Hyper-V Features
As a lead-in to the virtualization topic and Hyper-V, I will start with a list of key features,
followed by a list of supported guest operating systems. This should provide you with a
quick, high-level view of this feature before you dig deeper into the technology.
Key Features of Hyper-V
The following are the key features of Hyper-V:
New Architecture The hypervisor-based architecture, which has a 64-bit micro-kernel,
provides a new array of device support as well as performance and security improvements.
Operating System Support Both 32-bit and 64-bit operating systems can run simultane-
ously in Hyper-V. Also, different platforms like Windows, Linux, and others are supported.
Support for Symmetric Multiprocessors Support for up to 64 processors in a virtual
machine environment provides you with the ability to run applications as well as multiple
virtual machines faster.
Network Load Balancing Hyper-V provides support for Windows Network Load Balanc-
ing (NLB) to balance the network load across virtual machines on different servers.
New Hardware Architecture Hyper-V's new architecture provides improved utilization of
resources such as networking and disks.
Quick Migration Hyper-V's quick migration feature provides you with the functionality
to run virtual machines in a clustered environment with switchover capabilities when there
is a failure. Thus, you can reduce downtime and achieve higher availability of your virtual
machines.
Virtual Machine Snapshot You can take snapshots of running virtual machines, which
provides you with the capability to recover to any previous virtual machine snapshot state
quickly and easily.
Resource Metering Hyper-V resource metering allows an organization to track usage
within the businesses departments. It allows an organization to create a usage-based billing
solution that adjusts to the provider's business model and strategy.
