Video: Cloud Tunnels @ Cloud Mafia

Building software defined networks for cloud computing has been a hot topic around the industry in the last year or so. There are blossoming open source projects, shiny new protocols and a few notable acquisitions.

At a recent Cloud Mafia meetup I gave a talk on the new emerging tunneling protocols that are being proposed to support cloud networking. My goal was to give the audience a sense of how these protocols work, why they are being built as they are and ultimately what the privacy and security concerns emerge as a result.

Slides are available (use the arrow keys to navigate) and a video of the talk is embedded below. For those tl;dr readers the major take-aways are:

• L2 in L3 tunneling is probably here to stay in the cloud
• Three emerging standards: VXLAN/NVGRE/STT
• In its raw form these protocols give a level of privacy but not security
• You should still use SSL/IPSec/etc between backend services

Thanks for watching.

This is the weblog of Brandon Philips and contains excerpts from my code, work and play.

I love writing systems software. At Rackspace I am the Engineer of Developer Happiness. At SuSE I was a Linux Kernel Hacker. And at Oregon State I interned at the Open Source Lab. In the world I contribute to open source software, volunteer to teach robotics and get out and about with a backpack, bike or pair of running shoes.

You might have seen me speak at Linux Plumbers Conf, Open Source Bridge, or Ignite Portland. In the past I helped organize Linux Plumbers Conf and Freedom HEC Taipei.
