Ensuring data consistency in a micro-service application

A few years ago, we had to rewrite an old mainframe application, used by a few thousand people. The application was known (or believed) to be fast, reliable and almost bug free. To maintain the level of service we chose a micro service architecture for the new solution, which means

Implementing SLI/SLO on End-to-End Critical User Journeys

When AI help us find a strong password

This article was co-authored by Edgar Peronnin, a Telecom Nancy student who wrote all the code, and Pierre Raufast, based on an initial idea by Maxime Escourbiac (CERT Michelin). Why is a strong password important? Password strength remains a key issue in cyber security. Indeed, password hashes are regularly compromised

Syncing on-premises Active Directory computer Distinguished Names to Azure Active Directory

Transitioning device management to the cloud has been one of our strategic directions for years but has proven easier said than done. So complicated in fact, that we are still operating in 2024 with hybrid devices (Hybrid Azure Active Directory-Joined - HAADJ), attached to both on-prem and cloud Microsoft environments,

Just like Michelin inspectors, we meticulously reviewed Devoxx 2024. Held in Paris from April 17-19, it attracted 4500 daily visitors and 70 exhibitors. The event enriched our tech journey, much like a Michelin-starred experience.

Data in motion, myth or reality

Data in motion, myth or reality

When I started to work in IT a couple decades ago, the center of the universe for a software engineer was databases, mostly relational ones. We were relying heavily on their transactional capabilities to ensure data consistency. Integrating an app with the rest of the world was quite a challenge.

Designing Kafka Streams Applications

Designing Kafka Streams Applications

For the past 4 years, our journey into the heart of Kafka's capabilities has been shaped by two pivotal concepts: Master Topologies and Micro Topologies. These conceptual frameworks have become the backbone of our Kafka Streams application design, offering a comprehensive and granular understanding of our end-to-end communication.

Actually, it’s not the network!

My job mostly consists of troubleshooting issues (performance, errors…) where it is not known whether the root cause lies with the application or the infrastructure. Many times, I hear “it’s the network’s fault”. Why is the network automatically blamed for no apparent reason? I will give you my
