Overcoming the Limitations of Hyper-V Virtual Networking

In my last post I talked about Microsoft’s implementation of Software-Defined Networking with Hyper-V virtual networking. Hyper-V virtual networking can dramatically improve an organization’s agility, allowing for the quick provisioning of supporting network resources in a virtualized infrastructure. In addition, virtual networking overcomes the constraints imposed by VLAN, allowing large enterprises and hosting providers to scale far beyond what is possible with conventional networking solutions.

Talking Microsoft Network Virtualization and Software-Defined Networking on RunAs Radio

Recently I had the opportunity to join host Richard Campbell on the popular IT Professional podcast RunAs Radio. Richard and I had a great conversation on the topic of Hyper-V Network Virtualization (HNV) and more broadly, Software-Defined networking (SDN). Software-defined networking is a compelling new feature included with Hyper-V and System Center Virtual Machine Manager (SCVMM) 2012 SP1. HNV allows administrators to define virtual networks that are independent of the underlying physical network, enabling important configuration and deployment scenarios such as cross-subnet live-migration and secure multi-tenancy.

Realizing the Full Potential of Hyper-V Network Virtualization

It’s an exciting time to be working with Microsoft private cloud technologies like Hyper-V. With the release of the Windows Server 2012 operating system, many new and compelling features have been included to enable private and hybrid cloud computing scenarios. One of the newest features is Hyper-V network virtualization (HNV). HNV is Microsoft’s vision for Software-Defined Networking (SDN). HNV is implemented using a network overlay, with configuration managed and maintained with System Center Virtual Machine Manager (SCVMM) 2012 SP1. HNV enables important new private cloud deployment models, however, there are some serious limitations with this technology.

Welcome to the Iron Networks Cloud Infrastructure Blog

As many of you know, back in March we changed our name from nAppliance Networks, to Iron Networks.  The reason for this change was that as we shifted our focus away from traditional network edge security and access products towards building up products focused on cloud-based infrastructures, so the nAppliance moniker no longer fit…it no longer represented what we were trying to accomplish.
