With new events happening every 20 minutes, outages could cost millions in lost sales. One of Kubernetes’ best features is…

#57 — Comprendre et utiliser le Chaos Engineering avec Sylvain Hellegouarch | Electro Monkeys

admin 2 months ago in

Le chaos engineering est une pratique, un état d’esprit, une attitude bien avant d’être un ensemble d’outils. Simuler une panne, un incident, ou l’absence du meilleur élément d’une équipe est facile ; l’outillage ne vient qu’ensuite, lorsqu’il s’agit d’automatiser toutes ces tâches. Mais l’outil doit-il s’arrêter là, ou doit-il aller plus loin pour permettre de réellement capitaliser sur les conséquences d’un problème, aussi bien pour…

Chaos engineering week at Track.health | by Dinuka Arseculeratne | Nov, 2020 | Medium

admin 3 months ago in

We were inspired by the Chaos engineering activities that were done by Netflix and wanted to test out of platform here at track.health to see how resilient we were on random failures. As a famous quote from the book Release It! Design and Deploy Production-ready Software by Michael T. Nygard; Enterprise software must be cynical. Cynical software expects bad things to happen and is never…

For more details refer to Chaos Engineering. Chaos experiments are executed in production environments, this leaves room for customer-facing outages. While there has to be some allowance for the short-term negative impact the blast radius or fallout…
