# Introduction
> NOTE: SeaweedFS provides **two mechanisms** to use cloud storage:
> 1) **SeaweedFS Cloud Drive** (**<== You are here**)
> - in this case, you can **mount** an S3 bucket to the Seaweedfs file system (in the filer), and access the remote files
> through SeaweedFS. Effectively, SeaweedFS caches the files from the cloud storage.
> - In this mode, the file structure in cloud store is exactly matching the SeaweedFS structure - so every
> file in SeaweedFS will also become a file in the cloud storage provider.
> - This is useful in case you want to use the files inside the cloud provider's infrastructure.
> - However, this does **not support file encryption** in any way (obviously), as the files are put to Cloud Storage as is.
> 2) [Tiered Storage with Cloud Tier](https://github.com/seaweedfs/seaweedfs/wiki/Cloud-Tier)
> - In this mode, seaweedFS **moves full volume files to the cloud storage provider**, so files which are 1 GB (in our case) big.
> - This mode supports [Filer Data Encryption](https://github.com/seaweedfs/seaweedfs/wiki/Filer-Data-Encryption) transparently.
> - The chunk files uploaded to the cloud provider are not usable outside of SeaweedFS.
SeaweedFS provides **two mechanisms** to use cloud storage:
1) **SeaweedFS Cloud Drive** (**<== You are here**)
- in this case, you can **mount** an S3 bucket to the Seaweedfs file system (in the filer), and access the remote files
through SeaweedFS. Effectively, SeaweedFS caches the files from the cloud storage.
- In this mode, the file structure in cloud store is exactly matching the SeaweedFS structure - so every
file in SeaweedFS will also become a file in the cloud storage provider.
- This is useful in case you want to use the files inside the cloud provider's infrastructure.
- However, this does **not support file encryption** in any way (obviously), as the files are put to Cloud Storage as is.
2) [Tiered Storage with Cloud Tier](https://github.com/seaweedfs/seaweedfs/wiki/Cloud-Tier)
- In this mode, seaweedFS **moves full volume files to the cloud storage provider**, so files which are 1 GB (in our case) big.
- This mode supports [Filer Data Encryption](https://github.com/seaweedfs/seaweedfs/wiki/Filer-Data-Encryption) transparently.
- The chunk files uploaded to the cloud provider are not usable outside of SeaweedFS.
