Video Whiteboard Series for Docker Universal Control Plane
It’s been less than two months since Docker Universal Control Plane (UCP) became generally available as part of the Docker Datacenter (DDC) subscription. With DDC, organizations are able to set up a Containers as a Service (CaaS) application environment on-premises/VPC … ContinuedAutomating Change With Help From Fibonacci
A few recent conversations that I’ve seen and had with professionals about automation have been very enlightening. It all started with a post on StackExchange about an unsuspecting user that tried to automate a cleanup process with Ansible and accidentally erased the entire server farm at a service provider. The post was later determined to be a viral marketing hoax but was quite believable to the community because of the power of automation to make bad ideas spread very quickly.
Better The Devil You Know
Everyone in networking has been in a place where they’ve typed in something they shouldn’t have. Whether you removed the management network you were using to access the switch or created an access list that denied packets that locked you out of something. Or perhaps you typed an errant debug command that forced you to drive an hour to reboot a switch that was no longer responding. All of these things seem to happen to people as part of the learning process.
But how many times have we typed something in to create a change and found that it broke more than we expected? Like changing a native VLAN on a trunk and bringing down Continue reading

A Baker’s Dozen, 2015 Regional View
Our Baker’s Dozen blog focuses on the top global Internet providers as measured by quantity of transited IP space. If your market is not truly global, it pays to consider your provider options by region, country or even city. Our Internet Intelligence product suite is designed around helping our customers understand the structure, performance and reliability of the Internet regardless of their geographic scope or potential providers. In other words, there is a lot more to consider than just a top global list by a single metric. To explore this topic further, we’ll look one geographic level deeper into the Internet Intelligence – Transit rankings for the top-5 providers by continent. As we’ll see below, these can vary considerably from our top global list and even include other players with a more regional focus. Let’s take a quick look.
At the end of 2015, Cogent (AS174) was ranked as the #4 global provider by our metric, but it closed the year as #1 in Africa, opening up a wide margin over Level 3 (AS3356), its nearest competitor on the continent. Cogent started transiting a sizeable number of new prefixes from South Africa’s Continue reading
First Guest Speaker in Building Next-Generation Data Center Course
When I started thinking about my first online course, I decided to create something special – it should be way more than me talking about cool new technologies and designs – and the guest speakers are a crucial part of that experience.
The first guest speaker is one of the gurus of network design and complexity, wrote numerous books on the topic, and recently worked on a hardware-independent network operating system.
