## Infrastructure as code
|
|
- Automatisation
|
|
- Fiabilité
|
|
- Efficacité
|
|
- Contrôle des versions
|
|
- Code = Infrastructre : autodocumenté
|
|
- Immutabilité

## Conteneurs
|
|
<ul>
|
|
<li>Ressources (processeur, ram)</li>
|
|
<li>Stockage</li>
|
|
<li>Réseau</li>
|
|
</ul>

|
|
- Horizontal Scaling
|
|
- Nombreuses platformes
|
|
- Kubernetes
|
|
- Docker Compose
|
|
- OpenShift

|
|
- Services internes ou publics
|
|
- DevOps (Déploiement et intégration continue)
|
|
- Technologies Cloud (AWS, Azure...) ou on-prem
