Virtual Kubernetes and Multi-Tenancy.
Create fully functional virtual Kubernetes clusters - Each vcluster runs inside a namespace of the underlying k8s cluster. It's cheaper than creating separate full-blown clusters and it offers better multi-tenancy and isolation than regular namespaces.
Virtual clusters are fully functional Kubernetes clusters nested inside a physical host cluster providing better isolation and flexibility to support multi-tenancy. Multiple teams can operate independently within the same physical infrastructure while minimizing conflicts, maximizing autonomy, and reducing costs.

An embedded database built on object storage.
Unlike traditional LSM-tree storage engines, SlateDB writes data to object storage to provide bottomless storage capacity, high durability, and easy replication.
SlateDB is an embedded storage engine built as a log-structured merge-tree. Unlike traditional LSM-tree storage engines, SlateDB writes data to object storage (S3, GCS, ABS, MinIO, Tigris, and so on). Leveraging object storage allows SlateDB to provide bottomless storage capacity, high durability, and easy replication. The trade-off is that object storage has a higher latency and higher API cost than local disk.
