The trade war between the United States and China is not just a top-down political and economic one, but also a technical one. …

It’s been one year since we started publishing the Docker Index (stats, trends and analysis from developers and dev teams based on anonymized data from millions of Docker users). At that time we saw how Docker was being used at an incredible scale to power application building globally. Today we are excited to share the latest edition of the Docker Index, this time with some yearly and quarterly comparisons.
Every time we pull these user stats, we are blown away by the sheer volume and continued growth in activity happening across the Docker developer community. It’s clear to see that collaborative application development platforms are the foundation for developers who want to build, share, and run modern apps. We are also thrilled to see this type of growth more than one year after refocusing Docker on making developers’ lives easier. The Docker community has stayed with us and continues to grow at a tremendous pace, giving us very encouraging signals about the path that Docker is taking.
To begin, there has now been a total of 318 billion all time pulls on Docker Hub, an increase of 145% year-over-year. That’s right, the total number of pulls has increased Continue reading
Today's Day Two Cloud gets into consulting. How do you start? What does the job entail? Is it a good job to have? How do you build a client base? There are so many questions! We're joined by Michael Jenkins, Sr. Systems Reliability Engineer at Managed Kaos; and Anthony Nocentino, Enterprise Architect at Centino Systems and Pluralsight author, to get some answers.

Every now and then I get a question along the lines of “why can’t we have a distributed SDN controller (because resiliency) that would survive network partitioning?” This time, it’s not the incompetency of solution architects or programmers, but the fundamental limitations of what can be done when you want to have consistent state across a distributed system.
TL&DR: If your first thought was CAP Theorem you’re absolutely right. You can probably stop reading right now. If you have no idea what I’m talking about, maybe it’s time you get fluent in distributed systems concepts after you’re finished with this blog post and all the reference material linked in it. Don’t know where to start? I put together a list of resources I found useful.

Meraki changed the industry years ago as one of the first platforms to use a cloud portal for all configuration; forgoing the typical local CLI/GUI administration of network appliances. One of the first things a traditional network engineer (like myself) may notice about Meraki equipment is their complete lack of a command-line interface. For the […]

As Andy Jassy takes over the CEO role at Amazon, the question is asked, “Does it matter who takes over at AWS, the position Jassy is vacating?” The idea is that AWS is such a dominant force in public cloud, an untrained monkey could sit at the helm and AWS would continue printing billions of dollars. So who cares who replaces Jassy? Whoever the new human is, they can’t get it wrong.
That might be exactly right, but for the thought exercise, I decided to go a different direction. For purposes of this opinion article, I choose to entertain the idea that Jassy’s replacement does matter, and matters a lot.
We can all agree that AWS is the 800 pound gorilla of public cloud. However, I believe AWS will see increasing pressure from all quarters. By way of comparison, let’s consider Cisco Systems of the last ten years.
Cisco has dominated the networking space in a variety of categories for a very long time. The last decade has seen them as the target all of their competitors aim at. In that context, did it matter who replaced John Chambers when he moved on? You Continue reading
The Dutch national supercomputer, called “Cartesius,” which is used for HPC education and research, is getting rather long in the tooth with some of its components being installed as far back as 2013. …

I’m teaching another master class over at Juniper on February the 10th at 12 noon PT (3PM ET):
It’s typical to think about scale, speed, oversubscription, and costs when designing a data center fabric. But what about security in a world increasingly focused on privacy, data protection, and preventing downtime caused by cyber breaches? This session will consider how data center fabric software and control plane components can impact security, including the ability to effectively manage segmentation policy, controlling failure domains, and the impact host-based routing has on fabric security.
Michael Shepherd, CTO at Rogers-O’Brien Construction, talks through his SD-WAN experience. He points out that it wasn’t hard to configure a full-mesh architecture. That’s a stark contrast to hugging your router dearly to your chest while reciting DMVPN configuration stanzas and staring at your phone in case you need to call TAC…who you have on […]

Early on in my career as a network engineer, I learned the value of sharing. When I could not figure out why a particular application was not working correctly, it was always useful to blame the application. Conversely, the application owner was often quite willing to share their problems with me, as well, by blaming the network.
A more cynical way of putting this kind of sharing is the way RFC 1925, rule 6 puts is: “It is easier to move a problem around than it is to solve it.”
Of course, the general principle applies far beyond sharing problems with your co-workers. There are many applications in network and protocol design, as well. Perhaps the most widespread case deployed in networks today is the movement to “let the controller solve the problem.” Distributed routing protocols are hard? That’s okay, just implement routing entirely on a controller. Understanding how to deploy individual technologies to solve real-world problems is hard? Simple—move the problem to the controller. All that’s needed is to tell the controller what we intend to do, and the controller can figure the rest out. If you have problems solving any problem, just call it Software Defined Continue reading
