VMware NSX is something something awesome
At times I have trouble focusing on writing articles for some of the presentations I am exposed to at Tech Field Day. Because of that, I really wanted to try something different. This article is more of my free-formed thoughts about NSX and why I’m excited to deploy it at my current $job. From the time I heard that the NSX team was going to be presenting at TFD15 for 4 hours, I knew that I would be writing this article because. Unfortunately it took me far too long to gather up this half formed thought.
First things first – NSX and Micro-Segmentation
I love the concept of Micro-Segmentation that NSX enables. Think of NSX as a virtual distributed firewall that is integrated with your hypervisor, but it really is so much more. This allows you to connect a security policy directly to the vNIC of your guest VM’s. Attaching it to the VM allows that policy to follow the VM anywhere, and everywhere it goes. You don’t have to worry about inter- or intra-VLAN segmentation as all of that is done on each vNIC. On top of that, NSX’s firewall is PCI DSS 3.2 compliant! Another rather compelling Continue reading

Bespoke Processors and the Future of Networks
As I spend a lot of time on Oak Island (not the one on television, the other one), I tend to notice some of those trivial things in life. For instance, when the tide is pretty close to all the way in, it probably is not going to come in much longer; rather, it is likely to start going back out soon. If you spend any time around clocks with pendulums, you might have noticed the same thing; the maximum point at which the pendulum swings is the point where it also begins swinging back. Of course my regular readers are going to recognize the point, because I have used it in many presentations about the centralization/decentralization craze the networking industry seems to go through every few years.
Right now, of course, we are in the craze of centralization. To hear a lot of folks tell it, in ten years there simply are not going to be routing protocols. Instead, we are going to all buy appliances, plug them in, and it is “just going to work.” And that is just for folks who insist on having their own network—for the part of the world that is not completely Continue reading
Automation and State
To State or not to State
State
State its purpose.
That is a state matter.
It was a messy night. Alice was filthy. She was in a state.
The router had some state.
What to do with state
Automation is a constantly changing state of affairs. It raises questions like:
a) If a service or API is idempotent, do I have to track state?
b) Should my workflows consider external state?
c) Should I normalise state?
Idempotency
Something is said to be idempotent if it gives you the same response if you call it repetitively.
I always view idempotency quite simply.
- Bob makes a terrible mistake building a NETCONF server for Alice.
- Alice punished Bob with the task of hoovering the office floor.
- Bob starts hoovering at 3pm when Alice is out of the office.
- Alice Tweets Bob mid-hoovering (because they’re millennials) with “Bob, it’s time to hoover.”.
- As Bob is idempotent, Bob carries on hoovering and ignores Alice’s Tweet.
If Bob wasn’t idempotent, he might have packed away the hoover, gotten it back out and started hoovering again (also assuming Bob was actually delivering on his punishment and hadn’t outsourced it to a cleaner).
Can you imagine the Continue reading

Flat OSPF network is not a problem ! But
Flat OSPF network, or single area OSPF networks are real. In fact most of the OSPF network today deployed, is flat OSPF networks. But how many routers can be placed safely in an OSPF area ? Any number from the real world OSPF deployment ? I will share in this post. Let me explain what […]
