Biography

I am a Solutions Architect at Google. I specifically work for Google Cloud Platform, for the EMEA SA team. You can see the work of the Google Solutions Architects here.

Born in Lyon, France, I have always had a taste for mathematics and physics. This lead me to study computer science at the Lycée du Parc. At the Ecole Centrale de Lyon, this new taste for computer science allowed me to invest myself heavily in the student computer association ECLAIR which serves, among other things, as an ISP for all students of the university. I finished my formal education at the Royal Institute of Technology of Sweden, also known as KTH, where I learned about cryptography, networks, and so many other things. Today, I still try to learn as much as I can on various topics such as Machine Learning or distributed systems.

My professional life began very much in accordance with the DevOps philosophy (even if I did not know it at the time) by designing the software development and CI workflow of the ANSSI, following some extremely strict security rules. My next job, at Oxalide, allowed me to gain a very important insight on the Ops side of the industry. Managing major web infrastructures on a day-to-day basis convinced me of the importance of the quality of the work earlier in the software lifecycle.

Today, my job is to help you make the best software possible at every level:

by choosing the right software architecture (micro-services, here I come!),

by ensuring that this software is production-ready (tests, 12-factor apps, etc.),

by running this software on highly efficient and resilient infrastructures,

by making your life easier and letting you concentrate on what you do well: coding great apps!

How to use Kubernetes to fix GKE

2017-05-29 kubernetes, iptables, gke, gcp, vpn

Note: Since writing this post, I joined Google. We have released a feature called IP Aliases that addresses the problem described in this article, and much more. I recently ran into a problem while using Google Container Engine (GKE), the managed Kubernetes by Google. This lead me to an interesting solution that can be used for a large range of issues you could encounter in Kubernetes. The Problem I was unsuccessfully trying to have my pods communicate with an application available through a VPN: everything was working as expected from a VM but the pods in the GKE cluster had no network connectivity with the services on the other side of the VPN.

AWS re:Invent 2016 - A recap (part II)

2017-01-02 aws, reinvent

This is the second and last part of my AWS re:Invent recap. Go check out the first part if you haven’t done so already. In this second post, I will outline the products announced by Werner Wogels during his keynote. You will also find a small opinionated analysis of the impact of each product, based on the current market and ecosystem. I tagged the really important ones with a [Game Changer] in the title.

AWS re:Invent 2016 - A recap (part I)

2016-12-17 aws, reinvent

Two weeks ago, thanks to my company, Oxalide, I had the chance to attend AWS re:Invent, in Las Vegas. This is the first part of a recap of all the announcements (yes, there are so many things to talk about that it doesn’t fit in a single post). You will also find a small opinionated analysis of the impact of each product, based on the current market and ecosystem.

Gitlab on Kubernetes + AWS

2016-11-04 aws, k8s, kubernetes, high-avaibility, gitlab

Update March 2017: EFS now supports a single mount point for a volume, so the setup is now much easier because you don’t have to differentiate between AZs. Take that into account while following this blog post. Introduction In the last post we saw how to create a production-ready Kubernetes (K8s) cluster on AWS with Kops. Now, let’s see how to use it in conjunction with AWS managed services to host a highly available application: Gitlab.

Kubernetes on AWS - Kops

2016-10-23 aws, k8s, kubernetes, high-avaibility, kops

Introduction Kubernetes is the leading container orchestration solution. It promises to standardize the way you run applications, without worrying if you are running on bare-metal, on a public cloud provider or on a private cloud. AWS being the leading public cloud solution, it is important to be able to run Kubernetes easily on this provider. In this post, I will show you how to create a production-ready Kubernetes cluster on AWS from scratch.
