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.

XML-to-JSON Information Loss, Cisco Nexus OS Edition
Last week I wrote about the interesting challenges you might encounter when using data generated by a Junos device in an Ansible playbook. Unfortunately it’s not just Junos – every system built around XML-based data structures might experience the same issues, including Cisco Nexus OS.
To be fair to Ansible developers: it’s not an Ansible problem, the problem is caused by fundamental incompatibility between XML and JSON encodings, and the naive use of standard XML Python libraries. It’s just that engineers who might stumble upon that problem commonly use Ansible.

Can automation help with fixing your network issues?
Automation is your extra pair of hands. Or even more than that. Capability to create the network automation solutions, from a basic scripts for info collection or simple configuration to complicated logic, which takes into account exiting environment and is integrated with your other OSS/BSS, is one of the key skills, what allows you to build a successful career in the constantly changing network field.

Is Computing A Right?
Recently, the idea of a cloud computing service delivered as a public utility was pitched to me. The idea was that computing power made available to those who would otherwise be unable to afford it would be a societal good. For example, imagine an academic group that needs compute for a research project. Or municipalities that would benefit their citizenry by leveraging a cloud-as-utility.

The History of the Cisco TAC
The Cisco Technical Assistance Center, or TAC, was as responsible for the growth of computer networking as any technology or other organization. TAC trained the first generation of network engineers, both inside Cisco and out, creating a critical mass of talent that spread out into the networking world, created a new concept of certifications, and set a standard that every other technical support organization has sought to live up to since. Join Joe Pinto, Phil Remaker, Alistair Woodman, Donald Sharp, and Russ White as we dive into the origins of TAC.
