Enterprises searching for an open source container attached storage solution for Kubernetes
About OpenEBS
OpenEBS builds on Kubernetes to enable Stateful applications to easily access Dynamic Local PVs or Replicated PVs. By using the Container Attached Storage pattern users report lower costs, easier management, and more control for their teams. OpenEBS is a 100% Open Source CNCF project made by MayaData & the community. Prominent users include Arista, Optoro, Orange, Comcast and the CNCF itself. Automated provisioning and storage replication across pods is challenging. OpenEBS makes complex cross-cloud stateful application storage easy. Unlike CSI plugins or Linux kernel dependent software, OpenEBS runs entirely in userspace, making deployment and maintenance a snap. The largest, most active Kubernetes storage project with the biggest user base and community, OpenEBS is built by K8s SREs, and experts just like you, tailored to their needs. OpenEBS orchestrates storage for any Kubernetes stack.

Longhorn
In the past, ITOps and DevOps have found it hard to add replicated storage to Kubernetes clusters. As a result many non-cloud-hosted Kubernetes clusters don’t support persistent storage. External storage arrays are non-portable and can be extremely expensive. Longhorn delivers simplified, easy to deploy and upgrade, 100% open source, cloud-native persistent block storage without the cost overhead of open core or proprietary alternatives. Longhorn’s built-in incremental snapshot and backup features keep the volume data safe in or out of the Kubernetes cluster. Scheduled backups of persistent storage volumes in Kubernetes clusters is simplified with Longhorn’s intuitive, free management UI. External replication solutions will recover from a disk failure by re-replicating the entire data store. This can take days, during which time the cluster performs poorly and has a higher risk of failure.

DRBD
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.
