OpenEBS
OpenEBS is an open-source cloud native storage platform for Kubernetes that delivers container-attached, software-defined storage for stateful workloads.
- Container-attached storage (cloud native storage) for Kubernetes clusters
- Software-defined storage engine stack with multiple data plane options
- Persistent storage for stateful containerized applications and databases
- Policy-driven storage provisioning, including replication and resilience controls
- Open-source project with community-driven development and integrations in the Kubernetes ecosystem
More About OpenEBS
OpenEBS is positioned as a cloud native storage (data management) project that runs directly on Kubernetes, providing persistent block and file storage for stateful workloads such as databases, message queues, and other data services. It follows a container-attached storage model, where storage controllers and data planes run as Kubernetes pods and are orchestrated by the same control plane as the applications they support. This approach targets environments where storage is expected to be provisioned, scaled, and managed using Kubernetes-native constructs.
The OpenEBS architecture is built around Kubernetes primitives such as StatefulSets, Deployments, and Custom Resource Definitions (CRDs), and integrates with the Container Storage Interface (CSI) (cloud storage interface) for dynamic provisioning of PersistentVolumes. Storage policies, replication factors, and performance characteristics can be expressed using Kubernetes StorageClasses, enabling infrastructure and platform teams to standardize storage behavior across namespaces, clusters, or environments. Because storage components run in user space as containers, OpenEBS aligns with GitOps and Infrastructure-as-Code (IaC) workflows commonly used in cloud native operations.
OpenEBS provides multiple storage engines (cloud native storage) that support different use cases and underlying infrastructures, such as local disks attached to Kubernetes nodes or external storage backends. These engines are designed to run in user space as containerized microservices, rather than requiring kernel modules or external storage appliances. This enables deployment on public cloud, private cloud, or on-premises (on-prem) Kubernetes clusters using commodity servers, with storage composed from available disks and attached volumes.
From an enterprise usage perspective, OpenEBS is applied in platform engineering, DevOps, and Site Reliability Engineering (SRE) contexts where teams run stateful workloads on Kubernetes and want storage that follows the same lifecycle and automation patterns as applications. It can be used to provide replicated storage for databases, logging and monitoring stacks, Continuous Integration and Continuous Deployment (CI/CD) systems, and other persistent services, or to expose high-performance local storage for single-node workloads. The project integrates with standard Kubernetes monitoring and observability tools, enabling metrics and logging for storage behavior alongside application telemetry.
In the broader marketplace taxonomy, OpenEBS fits within cloud native storage, software-defined storage, and Kubernetes data management categories. It is designed as an open-source, vendor-neutral option that can be deployed across multiple infrastructure providers while keeping storage orchestration inside the Kubernetes boundary. For directory and catalog purposes, OpenEBS can be grouped under container-attached storage (cloud native storage), Kubernetes storage orchestration, and data management for stateful containerized applications.
