One of the attendees of my Building Next-Generation Data Center course asked this interesting question after listening to my description of differences between Chet/Puppet and Ansible:
For Zero-Touch Provisioning to work, an agent gets installed on the box as a boot up process that would contact the master indicating the box is up and install necessary configuration. How does this work with agent-less approach such as Ansible?
Here’s the first glitch: many network devices don’t ship with Puppet or Chef agent; you have to install it during the provisioning process.

I chose the LS2208 because there were lots of them on eBay and because documentation was available. So far I'm happy with the LS2208, but wish it didn't require a physical PC to be nearby.

It’s been a long time since my last post, way longer than I’d like. For the last several months we’ve been neck deep in network automation. This post focuses on the highlights of not only what I’ve been up to, but also the rest of the Network to Code team. More detailed posts will come over the coming days and weeks.
As you can see from the website, we have a good number of public courses on network automation and even a few starting early next year that are completely virtual, but the majority of our training engagements have been private on-site instructor-led courses with Enterprises and Global Carriers. The private courses have varied from using the same course outline you see on the website, but have also been modified for a particular vendor, device type, and/or API. Popular topics covered in our training include Ansible, Python, NETCONF/RESTCONF/YANG, and various vendor APIs including Nexus NX-API, Arista eAPI, Juniper’s XML API, to Cisco’s new NETCONF/RESTCONF APIs on IOS XE.
We’ve contributed to various open source projects, but key highlights include contributions to Ansible modules that are now part of core as well as adding Palo Alto Networks (PAN) Continue reading

Everyone talks about security on infrastructure, but it comes at a heavy cost. While datacenters have been securing their perimeters with firewalls for decades, this is far from sufficient for modern applications.
Back in the early days of the Internet, all traffic was from the client in through the web and application servers to the back-end database that fed the applications – what is known as north-south traffic in the datacenter lingo. But these days, an application is a collection of multiple services that are assembled on the fly from all over the datacenter, across untold server nodes, in what …
