## What it is
CubeFS is a CNCF-graduated, cloud-native distributed file and object storage system written in Go. It supports S3, HDFS, and POSIX access protocols with replica and erasure-coding engines, scaling to PB/EB sizes and integrating with Kubernetes via a CSI driver.

## Use cases
- self-host S3-compatible object storage on my own cluster
- distributed file system for Kubernetes containers with a CSI driver
- storage backend for big data and Hadoop workloads
- shared POSIX file storage for AI/LLM training platforms
- build an EB-scale storage service with erasure coding
- separate storage from compute for databases and middleware
- multi-tenant storage with fine-grained isolation

## When to choose
- you need a scalable, multi-protocol (S3/HDFS/POSIX) storage system on Kubernetes or bare metal
- you want CNCF-graduated, production-proven distributed storage with replica and erasure-coding options
- you need multi-tenant isolation and multi-level caching for large-scale data platforms

## When to avoid
- you only need simple single-node file storage or a lightweight NAS replacement
- you want a managed cloud storage service rather than operating your own cluster
- you need block storage volumes for databases rather than file/object storage
