Transition tiers can be added to MinIO using `mc admin tier add` command to associate a `gcs`, `s3` or `azure` bucket or prefix path on a bucket to the tier name.
Lifecycle transition rules can be applied to buckets (both versioned and un-versioned) by specifying the tier name defined above as the transition storage class for the lifecycle rule.

## Let's Encrypt

Avant Let's Encrypt, ces certificats HTTPS étaient vendus par des tiers de confiance.

Le processus d'acquisition d'un de ces certificats était auparavant lourd, nécessitait pas mal de paperasses et les certificats étaient assez chers.
