At a Glance:
Garage is an S3-compatible distributed object storage service built for self-hosting at small-to-medium scale, designed to replicate data across nodes at different physical locations and remain available during partial network or machine failures.
Overview:
Garage is a distributed object storage service that implements the S3 API for self-hosted environments at small-to-medium scale. It is designed for storage clusters composed of nodes running at different physical locations, providing data replication across geo-distributed sites while maintaining availability even when some servers become unreachable. The project focuses on being lightweight, easy to operate, and highly resilient to machine failures. Garage was built by Deuxfleurs, an experimental small-scale self-hosted service provider, and has been used in production since its first release in 2020.
Key Decision Points:
Self-hosted geo-distributed storage: Designed for clusters with nodes at different physical locations, not limited to single-site deployments.
S3-compatible API: Works with any tool, SDK, or application written for the S3 object storage protocol.
Small-to-medium scale focus: Optimized for modest deployments rather than hyperscale cloud environments.
Resilience model: Maintains availability during partial network partitions and recovers from machine failures without requiring all nodes to be online.
Production-proven: Actively used in production by its creators at Deuxfleurs since 2020.
Core Features:
S3 API compatibility: Provides an HTTP endpoint compatible with the S3 object storage protocol, enabling integration with existing S3 clients and SDKs.
Geo-distributed replication: Replicates object data across nodes deployed at different physical locations using configurable replication policies.
Resilience to partial failures: Continues serving data even when some cluster nodes are unreachable due to network issues or machine failures.
Lightweight operations: Designed to be easy to deploy, configure, and maintain with low operational overhead.
AGPLv3 licensing: Released as entirely free software under the AGPLv3 license.
Use Cases:
Developers and self-hosters who need S3-compatible object storage they can deploy across geographically distributed locations.
Small-to-medium scale deployments where data availability during partial network outages is important.
Self-hosted service providers looking for an object storage backend that replicates data across physical sites.
Open-Source Alternative Value:
Garage provides a self-hosted distributed object storage option with native S3 compatibility, designed specifically for geo-distributed deployments rather than single-datacenter clusters. Its architecture directly addresses replication and availability across different physical locations, which differentiates it from object storage solutions that assume co-located nodes. The project is backed by production experience at Deuxfleurs since 2020, demonstrating practical viability for small-to-medium scale self-hosting use cases.
