Community Spotlight series: Calico Open Source user insights from Ana Shmygla and Josef Janda, Jamf
In this installment of the Calico Community Spotlight series, I interviewed Ana Shmyglya and Josef Janda, who both work for Jamf. Last year, Josef wrote Migrating CNI plugin from kube-router to Calico on Kops managed Kubernetes cluster, and I wanted to dive deeper into his and Ana’s experience based on that blog post. We mainly talked about their respective teams, their responsibilities, and the challenges they have faced whilst using Kubernetes.
Q: What are your current roles and primary responsibilities?
Ana: I work in the Platform team. This basically means I am responsible for a team that maintains the core infrastructure, which includes the Kubernetes clusters that we run. We also own the underlying CNI of the clusters.
Josef: I work as a DevOps engineer on the team that maintains the internal development tools and other systems connected to the software delivery life cycle process.
Q: What orchestrator(s) have you been using?
Josef: We use Kubernetes. That’s basically the only orchestrator in our company.
Ana: Same for us as well, it’s Kubernetes across the company.
Q: What cloud infrastructure(s) has been part of your projects?
Ana: We use a couple of different providers, including AWS, but we only run Continue reading

It’s been a great week at Networking Field Day 28 this week with some great presentations and even better discussions outside of the room. We recorded a couple of great podcasts around some fun topics, including the Full Stack Engineer.
Some random thoughts about that here before we publish the episode of the On-Premise IT Roundtable in the coming weeks:
- Why do you need a full stack person in IT? Isn’t the point to have people that are specialized?
- Why does no one tell the developers they need to get IT skills? Why is it more important for the infrastructure team to learn how to code?
- We see full stack doctors, which are general practitioners. Why are there no full stack lawyers or full stack accountants?
- If the point of having a full stack understanding is about growing non-tech skills why not just say that instead?
- There’s value in having someone that knows a little bit about everything but not too much. But that value is in having them in a supervisor role instead of an operations or engineering role. Do you want the full stack doctor doing brain surgery? or do you want him to refer you to a Continue reading
The Cloudflare Bug Bounty program and Cloudflare Pages
The Cloudflare Pages team recently collaborated closely with security researchers at Assetnote through our Public Bug Bounty. Throughout the process we found and have fully patched vulnerabilities discovered in Cloudflare Pages. You can read their detailed write-up here. There is no outstanding risk to Pages customers. In this post we share information about the research that could help others make their infrastructure more secure, and also highlight our bug bounty program that helps to make our product more secure.
Cloudflare cares deeply about security and protecting our users and customers — in fact, it’s a big part of the reason we’re here. But how does this manifest in terms of how we run our business? There are a number of ways. One very important prong of this is our bug bounty program that facilitates and rewards security researchers for their collaboration with us.
But we don’t just fix the security issues we learn about — in order to build trust with our customers and the community more broadly, we are transparent about incidents and bugs that we find.
Recently, we worked with a group of researchers on improving the security of Cloudflare Pages. This collaboration resulted in several security vulnerability Continue reading
Why I joined Cloudflare in Latin America
This post is also available in Español, Português.
I am excited to announce that I recently joined Cloudflare as Vice President and Managing Director for Latin America. As many of you reading this likely already know, Cloudflare is on a mission to help build a better Internet. And that’s a big part as to why I joined this team — to contribute to this in Latin America specifically and interconnect all across the world. Cloudflare has had a strong presence in Latin America for years. First investing in the region back in 2014, when it expanded its network into Latin America to be closest to the users here — to provide even faster and reliable connections without compromising security. Over the past couple of years, our reliance on the Internet has increased, and Latin America is the fourth largest region in terms of online users globally. You can see how this makes Cloudflare’s mission even more important and presents a significant opportunity in Latin America.

Check out this preview of JuniperNetworks upcoming 2022 Global Summit in this discussion of panelists featuring our CTO Stefan Fouant alongside fellow Ambassador Nupur Kanoi, Mike Marcellin, Juniper CMO, and Zeus Kerravala where they discuss “Experience First Networking” and deriving more value from your network.Live Training: How Routers Really Work
On the 27th of May, I’ll be teaching a three-hour course called How Routers Really Work? From the course description:
This training will peer into the internal components of a router, starting with an explanation of how a router switches packets. This walk through of a switching path, in turn, will be used as a foundation for explaining the components of a router, including the various tables used to build forwarding tables and the software components used to build these tables.
