Editor's Notes
- #4 Spirale NEGATIVE
- #5 DEV: changes into production as quickly as possible OPS: stable, reliable, and secure, making it difficult or even impossible for anyone to introduce production changes that could jeopardize (Problème comptable et objectifs différents entre dev et ops )
- #6 même en tant que ops j’en peut plus d’attendre la création d’un environment
- #9 DevOps ne signifie pas q’un dev peut se passer des ops.Chauqun son metirer ; Collaborer Exemple de spécialisation .
- #11 Quick fix ok , mais il faut ensuite il faut améliorer
- #14 serveur = commodité (EX : prise de courant éléc) STOP Reboot
- #15 SINGLE REPOSITORY : application code , dependencies (e.g., libraries, static content, etc.), infrastructure, deploy, Any script used to create database schemas, application reference data, etc, All the environment creation tools and artifacts described in the previous step (e.g., VMware or AMI images, Puppet or Chef recipes,
- #17 What problems are we trying to solve?

- #20 ON DEMAND EASIER TO REBUILD THAN TO REPAIR
- #23 Pipeline Important (aussi pour les Ops)
- #27 Mise à jour système ( Infra as code) , java, librairies ,… Open Web Application Security Project

- #31 Automatiser! Ansible, kubernetes, simple shell script, git,… Exemple Facebook (dark launch)
- #33 Notifier uniquement si nécessaire Moins de notifications plus d’actions
- #34 Analyser vos métriques
- #36 Si vous voulez aller plus loin et mieux comprendre les interactions
- #37 Vous devez aussi monitorer votre CI/CD
- #38 Ops: partages les logs!!! On perd juste du temps avec la boucle infernale des logs « protégées »
- #39 Utilises plus les logs! tenez compte que vous n’êtes pas les seuls à les lire! Mais c’est difficile d’examiner des fichiers de lois pour les humains donc…
