Ryu, an openflow controller, was new to me. After doing 5 minutes of reading I knew I needed to get it up in the lab. The thing that caught my eye was that the project page was boasting support for OpenStack. Now, I don;t really have much experience with openstack, but it has a cult like following and it’s on my short list of stuff to get involved with. This seemed like a great excuse.
Buzz, Buzz, Buzz. The SDN sites are all abuzz with talk about how your enterprise network can take advantage of the deluge of new products and services out there aimed at that market, and that’s great - there are some cool options out there for that space. But, like I always do, I want to talk about the other pieces that most people do not see. The gritty plumbing and complex interconnections of the last mile providers, because there are a lot of very interesting moving parts there that the typical data center engineers don’t see, care about, or perhaps even know exist.
I recently had a very interesting and enjoyable conversation about firewall placement in a campus environment. Firewall in the center Firewall at the edge Firewall closest to the resource it needs to protect

I have been remiss in writing in the last year, the reasons are unimportant, but regardless, I’ve been paying very close attention. It’s 2017 and it is SOAPBOX time again! SDN has been a “thing” since ~2008, with the publication and popularization of the OpenFlow protocol. It’s 2017. How much has this industry changing technology is running outside of the hyper scale data centers? We’ve seen companies rise and companies disappear.

The networking world has been abuzz with talk of VMWares NSX announcement, Cisco’s CTO response to that, and heavy speculation of what that means. If you’re curious about NSX, Ivan Pepelnjak over at ioshints has a great write up explaining what it is and isn’t. I enjoyed the read quite a bit. Speculation generally makes me jittery, so I have spent some time thinking about this, reading and trying to understand.
