JNCIE-DC lab in EVE-NG tips and tricks
After having some feedback regarding my previous post on running the JNCIE-DC self-study workbook in EVE-NG. I wanted to share some of the most common questions I personally experienced while using the lab and general things to be aware of and some tips! I also ran into some aspects of going through the workbook that […]

Car Warranty vs Technology Service Contract
I’ve been struggling with the value of service contracts on IT equipment for some time now. As a rule of thumb, service contracts on IT infrastructure cost ~30% of the purchase price. This means that over three years of ownership you will pay the purchase price again. Which is quite a thing. I’m struggling to […]
Using New Ansible Utilities for Operational State Management and Remediation
Comparing the current operational state of your IT infrastructure to your desired state is a common use case for IT automation. This allows automation users to identify drift or problem scenarios to take corrective actions and even proactively identify and solve problems. This blog post will walk through the automation workflow for validation of operational state and even automatic remediation of issues.
We will demonstrate how the Red Hat supported and certified Ansible content can be used to:
- Collect the current operational state from the remote host and convert it into normalised structure data.
- Define the desired state criteria in a standard based format that can be used across enterprise infrastructure teams.
- Validate the current state data against the pre-defined criteria to identify if there is any deviation.
- Take corrective remediation action as required.
- Validate input data as per the data model schema
Gathering state data from a remote host:
The recently released ansible.utils version 1.0.0 Collection has added support for ansible.utils.cli_parse module, which converts text data into structured JSON format. The module has the capability to either execute the command on the remote endpoint and fetch the text response, or Continue reading

How Important is BGP RPKI?
Corey Quinn mentioned me in a tweet linking to AWS announcement that they are the biggest user of BGP RPKI (by the size of signed address space) worldwide. Good for them – I’m sure it got their marketing excited. It’s also trivial to do once you have the infrastructure in place. Just saying…
On a more serious front: how important is RPKI and what misuses can it stop?
If you’ve never heard of RPKI, the AWS blog post is not too bad, Nick Matthews wrote a “look grandma, this is how it works” version in 280-character installments, and you should definitely spend some time exploring MANRS resources. Here’s a short version for differently-attentive ;))

Get the Network Out of the Way
Getting the network out of the way has been very important for me in my thinking about networks, and is an easy way to help talk about a bunch of very important concepts, decisions, and arguments. This can sound trite, obvious, or insulting. In this post I’ll try to describe...What Gelsinger Can Do To Unscrew Intel
A little more than a week ago, Intel announced that Pat Gelsinger, its former chief technology officer and former manager of the predecessor of its Data Center Group as well as the current chief executive officer at server virtualization juggernaut VMware, would be returning to the world’s biggest chip maker to be its CEO and to take on the task of rescuing the company from itself and its competition. …

Graphcore IPU Put Through the Supercomputing Paces
With performance comparable to the Nvidia V100 GPU, a common accelerator in HPC but better energy consumption numbers and memory bandwidth potential, Graphcore can turn heads in supercomputing.
