## What it is
OpenStack Swift is a distributed object storage system that scales from a single machine to thousands of servers, optimized for multi-tenancy and high concurrency. It exposes a simple REST-based API (with S3 API compatibility) for storing unstructured data such as backups, web and mobile content, and other unbounded data.

## Use cases
- self-host an S3-compatible object store for backups
- store and serve web and mobile content at scale
- build a multi-tenant storage cloud for unstructured data
- replace or complement cloud object storage with on-premise infrastructure
- store large amounts of log files, images, or media that grow without bound
- provide a REST API for object storage across thousands of servers

## When to choose
- you need a proven, battle-tested distributed object store that scales horizontally to thousands of nodes
- you are already running OpenStack or want tight integration with its ecosystem
- you need multi-tenancy and high concurrency for many simultaneous clients
- you want an S3-compatible API on self-hosted infrastructure
- you need eventual-consistency guarantees with built-in replication and repair

## When to avoid
- you only need simple file storage on a single server or NAS
- you want block or POSIX filesystem semantics rather than object storage
- you need strong consistency for every read and write
- your team cannot operate a multi-service distributed cluster (proxy, storage, consistency workers)
- you just need a lightweight S3 gateway in front of existing disks
