For the last four years I’ve worked on Network Functions Virtualization (NFV) projects at a couple of European Cloud Service Providers (CSPs). The implementation of these projects has proven to be messy (messiness is part of human nature, after all), and I wanted to share some of the lessons I’ve learned.

In this issue of the Calico Community Spotlight series, I’ve asked Burak Tahtacioglu from ParkLab Technology to share his experience with Kubernetes and Calico Open Source. Let’s take a look at how Burak started his Kubernetes journey, and the insights he gained from Calico Open Source.
Q: Please tell us a little bit about yourself, including where you currently work and what you do there.
I am a Sr. Software Developer in our Developer Experience team. I’m in charge of a team that maintains the core infrastructure, which includes the Kubernetes clusters we run. We also have the base CNI of the clusters. I am mainly responsible for Kubernetes processes, Istio service mesh, and Apache APISIX API Gateway processes of scaled applications.
Q: What orchestrator(s) have you been using?
Kubernetes.
Q: What cloud infrastructure(s) has been a part of your projects?
Amazon EKS and RKE.
Q: There are many people who are just getting started with Kubernetes and might have a lot of questions. Could you please talk a little bit about your own journey?
I first used container (LXC) processes in my development environment and applied them to the applications I was consulting. Then I started my Continue reading
This article describes how use the instrumentation built into ConnectX SmartNICs for data center wide network visibility. Real-time network telemetry for automation provides some background, giving an overview of the sFlow industry standard with an example of troubleshooting a high performance GPU compute cluster.
Linux as a network operating system describes how standard Linux APIs are used in NVIDIA Spectrum switches to monitor data center network performance. Linux Kernel Upstream Release Notes v5.19 describes recent driver enhancements for ConnectX SmartNICs that extend visibility to servers for end-to-end visibility into the performance of high performance distributed compute infrastructure.
The open source Host sFlow agent uses standard Linux APIs to configure instrumentation in switches and hosts, streaming the resulting measurements to analytics software in real-time for comprehensive data center wide visibility.
Packet sampling provides detailed visibility into traffic flowing across the network. Hardware packet sampling makes it possible to monitor 400 gigabits per second interfaces on the server at line rate with minimal CPU/memory overhead.psample { Continue reading
We discuss how Kolide tools engage the user to improve end-point security. Monitoring devices and then contacting the user to gather more information and provide contextual questions is a novel approach.
