Midokura, Cumulus Bridge Virtual & Reality

Mitch Wagner

Midokura and Cumulus Networks are collaborating on server software designed to help connect virtual networks with stick-in-the-mud applications that insist on remaining grounded in reality. Certain applications, such as legacy and database software, cannot be virtualized and have to run on physical servers. In other cases, business managers won't allow the applications to be virtualized. These applications can be like anvils, weighing down service providers' efforts to virtualize their networks.

Midokura and Cumulus's server is designed to provide connections at line speeds between applications running on physical servers with other workloads running on virtual machines on a virtual network. The companies plan a technology preview by May, with general availability in the third quarter.

Midokura develops software designed to allow Web-scale cloud providers -- companies building enormous clouds to rival Facebook or Amazon -- to virtualize their networks. Rather than using an SDN approach, which requires running on commodity open-switch hardware, Midokura boasts that its MidoNet software runs as an overlay network, allowing cloud providers to keep their existing network infrastructures. (See Midokura Does Net Virtualization at Web Scale and Defining SDN & NFV.)

Cumulus develops a Linux OS that runs on data center networking hardware. (See Dell Opens Arms to Cumulus OS.) The joint server will allow MidoNet to connect to physical switches running Cumulus Linux, allowing network traffic flows from virtual machines to physical machines through the VxLAN Tunnel Endpoint (VTEP) gateway.

Re: Left behind
 Dan, I don't know the answer to your question but it seems to me to you are correct. This will be an essential feature for all SDN platforms. Just about every business has applications that it can't afford to leave behind.

Re: Left behind
I agree that service providers need to look at this -- so they can address the needs of customers who have a combined set of workloads that include legacy apps and newly deployed apps (such as app servers like Nginx or Tomcat) that may run in a virtualized environment.

Left behind
When the SDN rapture comes, what are other vendors--and service providers--doing to make sure legacy apps dont get left behind the times? This seems like a decent enough idea froma couple fairly new companies, and the vendors already serving customers with such apps should have a ready answer themselves.

Broadband speeds are ramping up across Europe as the continent, at its own pace, follows North America towards a gigabit society. But there are many steps to take on the road to gigabit broadband availability and a number of technology options that can meet the various requirements of Europe’s high-speed fixed broadband network operators. During this radio show we will look at some of the catalysts for broadband network investments and examine the menu of technology options on offer, including vectoring and for copper plant evolution and the various deployment possibilities for FTTH/B.
