Data Center Virtualization – Hyper-V Ecosystem

MSFT_logo500x300In addition to the Hyper-V role found within Windows Server, Microsoft also released a separate edition of Hyper-V, namely, Microsoft Hyper-V Server. Microsoft Hyper-V Server is a hypervisor-based server virtualization product that enables organizations to consolidate workloads, improving server utilization and reduce costs. Microsoft Hyper-V Server is a dedicated, no-cost, standalone product that contains the hypervisor, Windows Server driver model, virtualization capabilities, and supporting components such as failover clustering, but does not contain the robust set of features and roles that the full Windows Server operating system has. As a result, Microsoft Hyper-V Server has a small footprint and minimal overhead.

Virtualized data centers are becoming more popular and practical every day. IT organizations and hosting providers have begun offering infrastructure as a service (IaaS), which provides more flexible, virtualized infrastructures to customers—“server instances on-demand.” Because of this trend, IT organizations and hosting providers must offer customers enhanced security and isolation from one another.If a service provider’s infrastructure is hosting two companies, the IT Admin must help ensure that each company is provided its own privacy and security. Before Microsoft Hyper-V Server, server virtualization provided isolation between virtual machines, but the network layer of the data center was still not fully isolated and implied layer-2 connectivity between different workloads that run over the same infrastructure. For the hosting provider, isolation in the virtualized environment must be equal to isolation in the physical data center, to meet customer expectations and not be a barrier to cloud adoption. Isolation is almost as important in an enterprise environment. Although all internal departments belong to the same organization, certain workloads and environments (such as finance and human resource systems) must still be isolated from each other. IT departments that offer private clouds and move to an IaaS operational mode must consider this requirement and provide a way to isolate such highly sensitive workloads.

Microsoft Hyper-V Server provides enhanced capabilities and features that help consolidate servers effectively while making maximum use of resources.

Hyper-V Network Virtualization

Hyper-V Network Virtualization decouples server configuration from network configuration to provide multiple virtual dedicated networks. This enables seamless communications among virtual machines, and migration across physical servers, while isolating these networks from one another, enhancing security.

Hyper-V Extensible Switch

Hyper-V has been enhanced for virtual machine protection, traffic isolation, traffic prioritization, usage metering, and troubleshooting. To help integrate Hyper-V networking into existing infrastructures, the Hyper-V Extensible Switch provides for third-party extensions to work with existing monitoring and security tools, or with other specialized third-party functionality.

Virtual Machine Scale and Mobility

 Hyper-V Server has been enhanced, similarly to Hyper-V in Windows Server, and can host larger virtual machines with more virtual processors and memory – and host more of them on larger server clusters. These improvements, combined with other features such as Dynamic Memory, enable you to consolidate even very large workloads densely and efficiently.
Hyper-V Server enables tremendous flexibility in virtual machine placement and management throughout your virtual environment, through the inclusion of support for simultaneous live migrations, storage live migration, and shared-nothing live migration.
