# Data resiliency for everyone

Garage is an **open-source** distributed **storage service** you can **self-host** to fullfill many needs:

Garage implements the **[Amazon S3 API](https://docs.aws.amazon.com/AmazonS3/latest/API/Welcome.html)** and thus is already **compatible** with many applications:

Garage provides **data resiliency** by **replicating** data 3x over **distant** servers:

## Keeping requirements low

We worked hard to keep requirements as low as possible as we target the largest possible public.

  * **CPU:** any x86\_64 CPU from the last 10 years, ARMv7 or ARMv8.
  * **RAM:** 1GB
  * **Disk Space:** at least 16GB
  * **Network:** 200ms or less, 50 Mbps or more
  * **Heterogeneous hardware:** build a cluster with whatever second-hand machines are available

*For the network, as we do not use consensus algorithms like Paxos or Raft, Garage is not as latency sensitive.*
*Thanks to Rust and its zero-cost abstractions, we keep CPU and memory low.*
