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...Tech Bytes: VMware’s vRealize True Visibility Suite Illuminates Dark Corners Of Your IT Stack (Sponsored)

Today's Day Two Cloud episode is part one of a two-part show on abstractions. Hosts Ned Bellavance and Ethan Banks riff on the idea that "Abstractions are there to save you typing, not to save you thinking." The upshot? Abstractions don't eliminate issues, they just move them someplace else. And that has repercussions for design, development, infrastructure, and operations.Day Two Cloud 081: Abstractions Should Save Typing, Not Thinking

Calico Enterprise: An Overview
As we enter a new year, it’s an appropriate time to reflect on our achievements at Tigera and how much Calico Enterprise has evolved over the past year as the industry’s leading Security and Observability solution for Kubernetes Networking and Microservices. Our experience working with enterprise-class early adopters has helped us to identify the most critical requirements for them to operationalize their Kubernetes deployments and successfully make the challenging transition from pilot to production. These learnings have helped us to shape today’s Calico Enterprise, which is visually represented in this solutions architecture diagram. Let’s dig into this feature-rich layer cake of functionality, from bottom to top!
Calico Enterprise Solutions Architecture
Calico Enterprise is “Kube-native”
But first, there are some important things to keep in mind as we explore. Calico Enterprise is a Kubernetes-native solution – Kube-native – in which everything we do is an extension of Kubernetes primitives. We leverage the full power of Kubernetes by integrating with the Kubernetes API server and creating our own aggregated API server. We use an operator model to access and control custom resources to perform specific functions, like RBAC for example, natively in Kubernetes. Being Kubernetes-native means that as Kubernetes evolves, Calico Enterprise Continue reading
The Hedge Podcast 67: Daniel Beveridge and the Structure of Innovation
Innovation and disruption are part the air we breath in the information technology world. But what is innovation, and how do we become innovators? When you see someone who has invented a lot of things, either shown in patents or standards or software, you might wonder how you can become an innovator, too. In this episode of the Hedge, Tom Ammon, Eyvonne Sharp, and Russ White talk to Daniel Beveridge about the structure of innovation—how to position yourself in a place where you can innovate, and how to launch innovation.
Indigenous Communities Must Have Internet Access on Their Own Terms
A shorter version of this article was first published in the Toronto Star.
With the recent launch of the Universal Broadband Fund, or UBF, the federal government has committed to addressing the connectivity gap that is far too real for many people living in Canada. Over the past eight months, COVID-19 has shown us how important the Internet is during a crisis. Broadband access has become an essential service as critical as access to water or electricity. Minister Maryam Monsef was correct when she said: “High-speed Internet is more than just a convenience.”
Certainly, an investment of CAD$1.75 billion to help lower the hurdles that have left many Indigenous, rural, and remote communities in Canada on the wrong side of the digital divide is both needed and welcome. But officials need to take care not to disenfranchise the very communities they intend to help in the process. For the most challenging communities to connect to the Internet, success can only happen with community-led initiatives. It is critical that the communities most in need are full partners in the process, driving connectivity solutions that work for them, and have access to the necessary resources to make that happen.
