# Deployment { #deployment }

Deploying a **FastAPI** application is relatively easy.

## What Does Deployment Mean { #what-does-deployment-mean }

To **deploy** an application means to perform the necessary steps to make it **available to the users**.

## Overview

     * first one will be used to retrieve user principal.

5)  Store the encrypted OEK encrypted data key and master key ID in object metadata.

Only the root/admin user can perform an SSE-S3 key rotation using the Admin-API via [mc](https://github.com/minio/mc). For more details about how to perform key management operations using the CLI refer to [mc admin guide](https://github.com/minio/mc/blob/master/docs/minio-admin-complete-guide.md) or run `mc admin kms key`.
