Garage does not use RAFT or another +consensus algorithm internally to order incoming requests: this means that all requests +directed to a Garage cluster can be handled independently of one another instead +of going through a central bottleneck (the leader node). +As a consequence, requests can be handled much faster, even in cases where latency +between cluster nodes is important (see our [benchmarks](@/documentation/design/benchmarks/index.md) for data on this). +This is particularly usefull when nodes are far from one another and talk to one other through standard Internet connections. + +### Several replication modes + +Garage supports a variety of replication modes, with 1 copy, 2 copies or 3 copies of your data, +and with various levels of consistency. +Read our reference page on [supported replication modes](@/documentation/reference-manual/configuration.md#replication-mode) +to select the replication mode best suited to your use case (hint: in most cases, `replication_mode = "3"` is what you want). + +### Web server for static websites + +A storage bucket can easily be configured to be served directly by Garage as a static web site. +Domain names for multiple websites directly map to bucket names, making it easy to build +a platform for your user's to autonomously build and host their websites over Garage. +Surprisingly, none of the other alternative S3 implementations we surveyed (such as Minio +or CEPH) support publishing static websites from S3 buckets, a feature that is however +directly inherited from S3 on AWS. + +### Bucket names as aliases + + - the same bucket may have multiple names (useful when exposing websites for example) + + - bucket renaming is possible + + - Scoped buckets: 2 users can have a different bucket with the same name -> avoid collision. Helpful if you want to write an application that creates per-user bucket always with the same name. + +### Standalone/self contained + + +### Integration with Kubernetes and Nomad + +Many node discovery methods: Kubernetes integration, Nomad integration through Consul + +### Support for changing IP addresses + +(as long as all nodes don't change their IP at the same time) + +### Cluster administration API + +### Metrics and traces + +### (experimental) K2V API |
