It enables applications to store large blobs such +as pictures, video, images, documents, etc., in a redundant multi-node +setting. S3 is versatile enough to also be used to publish a static +website. + +Garage is an opinionated object storage solutoin, we focus on the following **desirable properties**: + + - **Self-contained & lightweight**: works everywhere and integrates well in existing environments to target [hyperconverged infrastructures](https://en.wikipedia.org/wiki/Hyper-converged_infrastructure). + - **Highly resilient**: highly resilient to network failures, network latency, disk failures, sysadmin failures. + - **Simple**: simple to understand, simple to operate, simple to debug. + - **Internet enabled**: made for multi-sites (eg. datacenters, offices, households, etc.) interconnected through regular Internet connections. + +We also noted that the pursuit of some other goals are detrimental to our initial goals. +The following has been identified as **non-goals** (if these points matter to you, you should not use Garage): + + - **Extreme performances**: high performances constrain a lot the design and the infrastructure; we seek performances through minimalism only. + - **Feature extensiveness**: we do not plan to add additional features compared to the ones provided by the S3 API. + - **Storage optimizations**: erasure coding or any other coding technique both increase the difficulty of placing data and synchronizing; we limit ourselves to duplication. + - **POSIX/Filesystem compatibility**: we do not aim at being POSIX compatible or to emulate any kind of filesystem. Indeed, in a distributed environment, such synchronizations are translated in network messages that impose severe constraints on the deployment. + +## Use-cases + +*Are you also using Garage in your organization?
