Hands On With #NetBeez - Part 2, in which Doris gets her oats. #nfd12

Continuing from my previous NetBeez post, I’d like to share some more detail on the charting and reporting capabilities of the product, and my experience using NetBeez to troubleshoot some real network issues. Incidentally, as advertising slogans go, this…
How does the NetBeez product shape up when you're in a crunch outage situation? I've spent some time hands on in a production network, and have feedback.

What to say about NXTWORK2016, Juniper’s second customer conference? In short, I’m impressed. The San Jose Marriot was once again the venue for the two-day NXTWORK conference, but this year things were clearly scaled up a little. Food tables which last…

Solarwinds ThwackCamp is back for 2016. Two days of free, online training isn't a bad deal, really. Why not give it a shot?

Microservices Gone Wild - Tech Dive Part 2: Build monolithic app in Go, then create #microservice functions in PHP. #golang

In this post, I’ll outline the program I’ll be using to demonstrate how microservices work. It’s written in go but it’s pretty straightforward. At the end of the series of posts I will upload all of these examples to github as well, in case anybody wants…

Blog: Response to @etherealmind's "CAM Table Basics" #comeandhaveagoifyouthinkyourehardenough ;-)

This post is a response to Greg Ferro’s recent Basics posts on (Content Addressable Memory) CAM tables. As this is a response post, you can assume that I don’t agree entirely with all of his definitions. Alternatively, perhaps I am totally wrong and I…
...in which I begin sparring with Greg Ferro over his CAM Table "Basics" posts, and see which of us can be the most picky.

Unwrapping Tangled Device Configurations - A10 Networks Edition

If you’ve ever tried to interpret an A10 Networks load balancer configuration, or some Cisco Modular QoS CLI commands, you’ll know that doing so involves following references to other parts of the configuration, inevitably ones that appear earlier in the…
Bored of back-tracking modular configurations to understand what's going on? Me too, so I created a handy tool for A10 Networks LB configurations.

Python versus Go - Fighting in Prime Time. A silly speed test with a surprising result.

Which is faster, Python or Go? And by how much? This is the question I found myself asking earlier this week after troubleshooting a script that my son had written in Python to calculate prime numbers. In The Red Corner – Python My son worked out a fairly…

Microservices Gone Wild – Tech Dive Part 3: Writing a #golang app to call the #microservices.

In this third post in the series about microservices, I’ll finish building my main application so that I can demonstrate a microservices-based application in action, albeit for a very basic set of functions. This post may be a little go-heavy in places,…

Tech Dive - Microservices Gone Wild (Part 1) #demo #onug /@gestaltit

I’ve heard a lot of noise about microservices in the last couple of years, perhaps most notably when I attended ONUG in Spring 2015 and Adrian Cockcroft from Battery Ventures (previously from Netflix) was pushing the idea of building applications using…
What is a microservice? How does it work? Why do I want microservices and why might I not want them in my environment? Get some answers here.
