A media service account is a Azure based account which gives you access to cloud based media services in Azure. Stores metadata of the media files you create, instead saving the actual media content. To work with media service account, you must have an associated storage account. While creating a media service account, you can either select the storage account you already have or you can create a new one. Since the media service account and storage account is treated separately, the content will be available in your storage account even if you delete your media service account Please be noted that your storage account region must be same as your media service account region.
