Edge Computing : learn to delegate

While the interest for the Internet of Things by companies is no longer to be proven, this area continues to give a hard time to experts, as for security and architecture. Indeed, the multiplication of data sources brings a reflection on the architecture of networks. As Satya Nadella (Microsoft CEO) said on stage in 2017: "When I joined Microsoft in 1992, all Internet traffic was 100 gigabytes a day. Today is 17.5 million times that amount ... per second! "And we are only at the…

Walkthrough: Watch your Ansible deployments in Grafana !

A few months ago our friends Guillaume Lefevre and Etienne Coutaud made an appearance at the 2017 KubeCon to present their work on a monitoring solution based on Prometheus and Grafana. (The video can be found here) A bit over a month later, we faced a problem in production, the platform started to behave abnormally. The graphs showed bursts in metrics which was unusual and some people were wondering if a deployment could have changed something in the configuration and triggered the problem. Even if…

The semicircle (episode 7 — Crisis / Opportunity)

Managers are not confronted with problems that are independent of each other, but with dynamic situations that consist of complex systems of changing problems that interact with each other.

Jeremy arrives first, he settles in near the projector and takes a sandwich out of his brown paper lunch bag. "So if I understand correctly, you propose that we spend the lunch break on the XXL code." "Yes. But just experimenting, mind you. It's a trial." "Don't bother justifying, I am joking."
