Build Your K8s Environment For The Real World Part 1 – Day Zero Ops
When you’re designing a Kubernetes environment, whether it’s small or large, there are a few things that you must think about prior to writing the code to deploy the cluster or implementing the GitOps Controller for all of your Continuous Delivery needs. First, you must plan. Planning is the most important phase. In blog one […]

Heavy Strategy 43 Is The IT Team In The Service, Project or Product Business
Differences between project (disruption, replacement), service (smooth, continuous) and product (updates, changes) mean that process and people have very different approach to technology management and operations.

Modernizing the WAN from Client to Cloud
The evolution of WAN architectures has historically paralleled that of application architectures. When we primarily connected terminals to mainframes, the WAN architecture was largely point-to-point links connecting back to data center facilities. As traffic converged to remove OpEx-intensive parallel network structures, the WAN evolved to architectures that enabled site-to-site connectivity in a full mesh or configurable mesh and then enabled multi-tenancy for carrier cost optimization.
External Links on Spine Switches
A networking engineer attending the Building Next-Generation Data Center online course asked this question:
What is the best practice to connect DC fabric to outside world assuming there are 2 spine switches in the fabric and EVPN VXLAN is used as overlay? Is it a good idea to introduce edge (border) switches, or it is better to connect outside world directly to the spine?
As always, the answer is “it depends,” this time based on:

The Networking RFCs: To read or not to read?
I see this question rather often asked on various social media. A post on Twitter a few days ago triggered this little blog post and I deeply appreciate the poster. The question was simple “Is it really necessary for an engineer to know or understand the key RFC numbers?”. Some of the engineers I work […]

Demo Bytes: Upgrading Network Devices With BackBox – Video
The BackBox network automation platform comes with many pre-built functions to make routine tasks performed by network administrators simple & foolproof. In this demo, BackBox’s Senior Product Manager Perry Greenwood shows Packet Pushers’ Ethan Banks how to automate network device upgrades using BackBox. We look at the entire lifecycle of the upgrade process, including scheduling, […]

Assume Disaster
One of the things that people have mentioned to me in the past regarding my event management skills is my reaction time. They say, “You are always on top of things when they go wrong. How do you do it?”
My response never fails to make them laugh. I offer, “I always assume something is going to go wrong. I may not know what it is but when it does happen I’m ready to fix it.”
That may sound like a cynical take on planning and operations but it’s served me well for many years. Why is it that things we spend so much time working on always seem to go off the rails?
Complexity Fails
Whether it’s an event or a network or even a carpentry project you have to assume that something is going to go wrong. Why? Because the more complex the project the more likely you are to hit a snag. Systems that build on themselves and require input to proceed are notorious for hitting blocks that cause the whole thing to snarl into a mess of missed timelines.
When I was in college studying project management I learned there’s even a term for Continue reading
Network Break 422: Microsoft Tasks Copilot To Do Your Drudge Work; Cisco Debuts A New Learning Platform
On this week's Network Break podcast we examine Palo Alto Networks adding AI Ops to its SASE offering, and Microsoft Copilot bringing AI into its suite of Office tools. The Ethernet Adapter market grew 22% in 2022, but not because more NICs were sold; we discuss the real reasons and cover more tech news.
