New capabilities with the Hyper-V Extensible Switch

The Hyper-V Extensible Switch in Windows Server 2012 RC introduces a number of new and enhanced capabilities for tenant isolation, traffic shaping, protection against malicious virtual machines, and hassle-free troubleshooting. The Extensible Switch allows third parties to develop plug-in extensions to emulate the full capabilities of hardware-based switches and support more complex virtual environments and solutions.

The Hyper-V Extensible Switch is a layer-2 virtual network switch that provides programmatically managed and extensible capabilities to connect virtual machines to the physical network. The Extensible Switch provides policy enforcement for security, isolation, and service levels. With built-in support for Network Device Interface Specification (NDIS) filter drivers and Windows Filtering Platform (WFP) callout drivers, it also allows for third-party extensible plug-ins that can provide enhanced networking and security capabilities.

The Hyper-V Virtual Switch Manager displays the extensions enabled for each virtual switch.

It is now easier for organizations to connect virtual machines to physical networks, and third parties can add virtual networking features and integrate the Hyper-V Extensible Switch into their hardware.

Multi-tenant security and isolation using the Hyper-V Extensible Switch

As virtualized data centers become more popular and practical, IT organizations and hosting providers have begun offering more flexible, virtualized infrastructures to customers. This new class of service, sometimes known as “server instances on demand,” is also called infrastructure as a service (IaaS). Hyper-V in Windows Server 2012 RC provides the platform capabilities needed for enterprises to create private clouds and transition to an IaaS environment. It also helps hosting providers build public clouds and offer IaaS solutions to their customers.

To enhance a more stable, safer computing environment for private clouds and IaaS environments, Windows Server 2012 RC contains new security and isolation capabilities that use the Hyper-V Extensible Switch. The Extensible Switch provides policy-based, software-controlled support for isolating multiple tenants while providing improved security.

Top benefits

The Hyper-V Extensible Switch helps organizations isolate multiple tenants and maintain security. The Extensible Switch also helps administrators to accommodate more tenants on the same infrastructure—and to provide access to this environment from their customers’ data centers. It helps large enterprises and hosting providers achieve the economies of scale required to reduce their cost structure. Hosting providers can also achieve the necessary revenue per customer or service by using the Hyper-V Extensible Switch.

Create extensible ‘Infrastructure as a Service’ offerings for Windows Server and Linux Virtual Machines. Leverage the power of System Center and Windows Server to easily create an Infrastructure as a Service solution for customers to provision and manage Windows Server and Linux VMs. This flexible multi-tenant solution puts Hosting Service Providers’ customers in control of how they grow their datacenter resources while lowering support costs.

Getting started yourself with Infrastructure as a Service from here

Hyper-V Network Virtualization lets you run multiple virtual networks on a single physical network. Each virtual network believes it is running on its own physical infrastructure.

The New Hyper-V Features include :

  • Ability of customers to keep internal IP addresses while moving workloads onto a shared IaaS cloud.
  • Flexible placement of workloads, which keep their IP addresses while being migrated or placed anywhere in the data center.
  •  Simplified migration and placement of server workloads, which are no longer dependent on underlying physical network
    configurations.
  • Tenant isolation that is enforced through software policies instead of through VLANs.
  • Increased flexibility of virtual machine workload placement, which simplifies network management and improves server and network resource usage.
  • Compatibility with existing infrastructure and emerging technologies, which allows Hyper-V network virtualization to be deployed in current data centers while remaining a viable option for emerging data center technologies.
  • Use of Windows PowerShell command-line interface or WMI to script and automate administrative tasks.

When you think of Sharepoint Online, Microsoft System Center 2012 products and Windows Azure, IT AS A SERVICE is comming up realy fast.
