+[OpenEBS](https://github.com/openebs/openebs) is an *open source storage platform* that provides persistent and containerized block storage for DevOps and container environments. 
+OpenEBS provides multiple storage engines that can be plugged in easily. A common pattern is the use of OpenEBS to deliver Dynamic LocalPV for those applications and workloads that want to access disks and cloud volumes directly.
 
 OpenEBS can be deployed on any Kubernetes cluster - either in cloud, on-premise or developer laptop (minikube). OpenEBS itself is deployed as just another container on your cluster, and enables storage services that can be designated on a per pod, application, cluster or container level.
