Simplyblock provides a distributed storage solution for IO-intensive and latency-sensitive container workloads in the cloud, offering an alternative to Elastic Block Storage services. The storage solution enables thin provisioning, encryption, compression, storage virtualization, and more. Ultra-high performance at low TCO, offering available for AWS, fully containerized, deployment. Up to 100x improved cost-to-performance over currently prevailing software-defined storage technologies like Ceph. Start from single node, grow to 255 nodes in a single cluster. Scales safely with zero downtime. Performance scales linearly. Storage entities (logical volumes) are provisioned and attached on cluster-level, no manual configuration required. Drop-in replacement for your current k8s storage solution. Offers easy integration via StorageClass. Write concurrently on multiple containers and nodes via distributed file system support.

DRBD® (Distributed Replicated Block Device) is an open source, software‑based, shared‑nothing block storage replication solution for Linux, designed primarily to deliver high-performance, high‑availability (HA) data services by mirroring local block devices between nodes in real time, either synchronously or asynchronously. Implemented deep in the Linux kernel as a virtual block‑device driver, DRBD ensures local read performance with efficient write‑through replication to peer(s). User‑space utilities like drbdadm, drbdsetup, and drbdmeta enable declarative configuration, metadata management, and administration across installations. Originally built for two‑node HA clusters, DRBD 9.x extends support to multi‑node replication and integration into software‑defined storage (SDS) systems such as LINSTOR, making it suitable for cloud‑native environments.
