OpenEBS is a container-native storage solution that provides replicated persistent volumes for Kubernetes workloads, using technologies like NVMe and the Mayastor engine to synchronously replicate data across multiple nodes for high availability. This video demonstrates how OpenEBS deploys storage engines as microservices within Kubernetes pods, in order to turn any available storage on worker nodes into replicated persistent volumes. A key point is that OpenEBS's replicated storage maintains complete copies of data on each node rather than sharding data across nodes like traditional distributed storage, which reduces the blast radius during failures.
