Using Ansible and NetBox to deploy EVPN on Arista
Ansible, Nornir, and other automation frameworks are excellent for generating and deploying configurations in an automated fashion. In Ansible, you can run a playbook, loop through hosts in your inventory file, and deploy configurations with host-specific information by leveraging host_vars and group_vars. Unfortunately, as your automation environment starts to grow and become more critical, you’ll […]

Agility vs. Flexibility
When you’re looking at moving to a new technology, whether it be SD-WAN or cloud, you’re going to be told all about the capabilities it has and all the shiny new stuff it can do for you. I would almost guarantee that you’re going to hear the words “agile” and “flexible” at some point during the conversation. Now, obviously those two things are different based on the fact there are two different words to describe what they do. But I’ve also heard people use them interchangeably. What does it mean to be agile? And is it better to be flexible too?
Agile Profile
Agility is the ability to move quickly and easily. It’s a quality displayed by athletes and fighters the world over. It’s a combination of reflexes and skill. Agility gives you the ability to react quickly to situations.
What does that mean in a technology sense? Mostly, agile solutions or methodologies are able to react to changing conditions or requirements quickly and adapt to meet those needs. Imagine a platform that can react to the changing needs of users. Or add new functions on the fly on demand. That’s the kind of agility that comes from software functionality Continue reading

Video: The Network Is Not Reliable
After introducing the fallacies of distributed computing in the How Networks Really Work webinar, I focused on the first one: the network is (not) reliable.
While that might be understood by most networking professionals (and ignored by many developers), here’s an interesting shocker: even TCP is not always reliable (see also: Joel Spolsky’s take on Leaky Abstractions).

What Content is Missing?
Prior to my current job, I enjoyed the time I invested in the community. I spent quite a bit of time on The Cisco Learning Network helping those that were early in career. I also blogged here regularly (typically weekly) and spent time in the Twitterverse and on Slack. From this perspective, taking a job with a vendor was more different than I expected. It was like someone flipped a switch and I was completely spent at the end of each and every day.
On a few occasions, I have tried to get back what I would have previously considered some level of normalcy with regards to the community. I have decided that this year is my year to make some major changes. I must do a better job prioritizing things I care about and realize that some [read many] things just aren’t going to get done. That is one thing I’ve learned over the past few years. Even though I have always felt that my workload was significant, there is nothing like having a job in which you can only get a small portion of the overall work completed. It just doesn’t feel good.
The community and the relationships Continue reading
