Audit Capacités DevOps/DORA

Le livre "Accelerate: The Science of Lean Software and DevOps: Building and Scaling High Performing Technology Organizations" (Gene Kim, Jez Humble, and Nicole Forsgren, 2018) s'appuie sur 5 ans d'études scientifiques pour faire ressortir les pratiques effectivement mises en oeuvre par les sociétés "tech" les plus performantes. (selon la classification de Westrum)

L'équipe de DORA (DevOps Research and Assessment) a identifié et validé un ensemble de capacités permettant d'optimiser les performances organisationnelles et celles de la livraison de logiciels. Ces articles décrivent comment mettre en œuvre, améliorer et mesurer ces capacités.

Les capacités recommandées sont au nombre de 27, classés en 3 catégories.

Update 25 April 2020:

Many thanks to @KZL1992 @tomslominski @ptrofi @n-thumann for recent comments on their experiences with 20.04 and Parallels 13/14/15, especially the subsitution of the latest prl-tools-lin.iso for older Parallels to get it going.

First off, credit goes to github.com/rudolfratusinski for leading the way here.

Single-page Application Project Structure

..with .NET / F# (or Node.js / Express), AngularJS (or Facebook React + RxJS), TypeScript, Gulp.js (or Grunt), NuGet...

Goals

Project structure should reflect application's logic (as opposed to regular MVC apps which all look the same)
Group assets by feature rather than by type (including views, scripts, documentation, tests etc.)
Allow developers to edit client-side and server-side code independently from each other
