First look into…. containerlab

There’s been many times in my career where I’ve wanted to build virtual networking labs – not just for testing network designs but primarily for learning. While studying for my CCIE, I remember using GNS3. It was pretty good but not always stable. I eventually moved to renting physical racks as I was spending as […]

KubeCon EU 2022 Wrap-Up

Starting a new job can be daunting. Attending your first KubeCon is certainly overwhelming. Starting a new job at a fast-paced startup, at KubeCon, while your suitcase has gone missing between Paris and Valencia was… memorable. When I decided to join Isovalent, I thought it would be extremely convenient to have my first day coinciding […]

Why I joined Isovalent

Networking is a hereditary thing for me. My mum worked for France Telecom – the national service provider – and my brother studied networks at university and started his career as a network consultant. It was incidentally his fault I ended up doing networking. He once left me a heavy training book and recommended I […]

HCP Packer Part 3: Integration with Terraform Run Tasks

In this third post in my HCP Packer series (you can also read Part 1 (Getting Started with HCP Packer) and Part 2 (Building a Go Client for HCP Packer)), I am going to cover some new features that have only just come out, as part of the General Availability of HCP Packer. I had […]

Deep Dive into Kubernetes Gateway API

What I find fascinating with Kubernetes is that, despite its popularity, it is always changing and evolving. Large-scale adoption brings more complex requirements and challenges. But bringing new technical features isn’t always the most difficult challenge – the complexity is in adapting Kubernetes to fit its operational model. That’s why the Kubernetes Gateway APIs were […]

Exploring eBPF – Part 3: Getting Started with Hubble

Welcome to the third post in my eBPF series: in my first post, I introduced eBPF and walked through how to use a sample code, in the second post, I talked about Cilium, an eBPF-based networking plugin for Kubernetes. In this third post, we’re going to jump straight from the previous post and leverage Cilium’s […]

Exploring eBPF – Part 2: Getting Started with Cilium

This is the second post in my eBPF series: in my first post, I shared my experience with applying my first basic eBPF code through the use of a tool called Bumblebee. In this part 2, I’m going to check out what is probably the most popular eBPF programs: Cilium. In part 3, we’ll look […]

Exploring eBPF – Part 1

I’ve been keeping an eye on eBPF for a little while. In fact, the first time I properly paid attention was when listening to one of my favourite Cloud podcasts: eBPF also caught my eye because the leading eBPF company out there (Isovalent) was cofounded by leaders in the cloud networking space and because they […]

Terraform and Splunk Part 3: Using the Terraform Provider for Splunk

This is the third post in my Terraform and Splunk series. After deploying Splunk with Terraform in Part 1 and setting up the Terraform Cloud integration in Splunk in Part 2, we are going to end this series for now by using Terraform to configure Splunk to monitor Terraform Cloud. For this, we are going […]

Terraform and Splunk Part 2: Setting up Splunk Dashboards and Searches with Terraform

This is Part 2 in a Terraform & Splunk Series. In Part 1, we deployed Splunk Enterprise using Terraform. The first part of my tests were actually based on Splunk Cloud as you can see from some of the screenshots below. Once I needed to use the Splunk APIs to configure Splunk with Terraform, I […]
