                Template que j'utilise pour auditer mes client sur les "capacités DevOps" proposées par le DORA, et leur donner des recommandations pour progresser. C'est en markdown => importable facilement dans Notion.
              
          
    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.

                Docker Swarm Port Requirements, both Swarm Mode 1.12+ and Swarm Classic, plus AWS Security Group Style Tables
              
          
    Docker Swarm Mode Ports

Starting with 1.12 in July 2016, Docker Swarm Mode is a built-in solution with built-in key/value store. Easier to get started, and fewer ports to configure.
Inbound Traffic for Swarm Management


TCP port 2377 for cluster management & raft sync communications
TCP and UDP port 7946 for "control plane" gossip discovery communication between all nodes
UDP port 4789 for "data plane" VXLAN overlay network traffic
IP Protocol 50 (ESP) if you plan on using overlay network with the encryption option

AWS Security Group Example

    How to setup AWS lambda function to talk to the internet and VPC

I'm going to walk you through the steps for setting up a AWS Lambda to talk to the internet and a VPC. Let's dive in.
So it might be really unintuitive at first but lambda functions have three states.

No VPC, where it can talk openly to the web, but can't talk to any of your AWS services.
VPC, the default setting where the lambda function can talk to your AWS services but can't talk to the web.
VPC with NAT, The best of both worlds, AWS services and web.
