One of my readers sent me a simple question: “Do you plan to have a Python for Networking Engineers webinar?”

Short answer: no immediate plans.

Here are just a few reasons:

Most network automation tutorials out there assume you’re running Ansible on your workstation and accessing virtual machines via SSH ports mapped by Vagrant. That’s great if you’re an experienced Ansible/Python user; for a clunky beginner like myself it’s safer to run Ansible within a VM that can be destroyed and recreated in seconds.

The featured webinar in December 2016 is the Network Automation Tools webinar, and in the featured videos you'll find in-depth description of automation frameworks (focusing on Ansible) and open-source IPAM tools (including NSoT recently released by Dropbox).

To view the videos, log into my.ipspace.net, select the webinar from the first page, and watch the videos marked with star.

I got several questions along the lines of “Do I need programming skills to attend the Building Network Automation Solutions course?”

Short answer: No.

A few days after I published the blog post describing why it might make sense to attend the Building Network Automation Solutions course even when you’re already using a $vendor network management system/platform, I got a surprising email from one of my friends working for a major networking vendor:

Every time I write about network automation in enterprise environments I get the usual set of excuses including:

Some of the environments I am looking at have around 2000-3000 devices and 6-7 vendors for various functions and 15-20 different device platform from those vendors. I am trying to understand what all environments can Ansible scale up to and what would be an ideal environment enterprises should be looking at more enterprise grade automation/orchestration platforms while keeping in mind that platform allows extensibility.

Luckily I didn’t have to write a response – one of the readers did an excellent job:

A few weeks ago Matt Oswalt wrote an interesting blog post on principles of automation, and we quickly agreed it’s a nice starting point for a podcast episode.

In the meantime Matt moved to StackStorm team so that became the second focus of our chat… and then we figured out it would be great to bring in Matt Stone (the hero of Episode 13).

Cisco VIRL is the ideal testing environment when you want to test your Ansible playbooks with various Cisco network operating systems (IOS, IOS XE, NX-OS or IOS XR). The “only” gotcha: how do you reach those devices from the outside world?

It was always possible to reach the management interface of devices running with VIRL, and it got even simpler with VIRL release 1.2.

Like with the Next-Generation Data Center course, the live sessions in the Building Network Automation Solutions course include guest speakers, Q&A discussions, and solutions to sample challenges that you’ll be able to use to complete your homework assignments.

The guest speakers for the January 2016 course include:

One of my readers wondered whether it makes sense to attend my Building Network Automation Solution course even if they plan to deploy a $Vendor platform.

It depends, this time on how fast and how far you want to proceed with network automation.
