## Overview
CubeFS ("储宝" in Chinese) is an open-source cloud-native distributed file & object storage system, hosted by the [Cloud Native Computing Foundation](https://cncf.io) (CNCF) as a [graduated](https://www.cncf.io/projects/) project.
## What can you build with CubeFS
* As an open-source distributed storage, CubeFS can serve as your datacenter filesystem, data lake storage infra, and private or hybrid cloud storage.
* Moreover, it can be run in public cloud services, providing cache acceleration and file system semantics on top of public cloud storage such as S3.
* In particular, CubeFS enables the separation of storage/compute architecture for databases, search systems, and AI/ML applications.
Some key features of CubeFS include:
- Multiple access protocols such as POSIX, HDFS, S3, and its own REST API
- Highly scalable metadata service with strong consistency
- Performance optimization of large/small files and sequential/random writes
- Multi-tenancy support with better resource utilization and tenant isolation
- Hybrid cloud I/O acceleration through multi-level caching
- Flexible storage policies, high-performance replication or low-cost erasure coding
