Vous pouvez **déployer un serveur** vous-même en utilisant une combinaison d'outils, vous pouvez utiliser un **service
cloud** qui fait une partie du travail pour vous, ou encore d'autres options possibles.

Je vais vous montrer certains des principaux concepts que vous devriez probablement avoir à l'esprit lors du déploiement

Let's take for example a set of 12 compute nodes with an aggregate memory of _1.2TiB_, we need to do following settings for optimal results. Add the following optimal entries for _core-site.xml_ to configure _s3a_ with **MinIO**. Most important options here are
