The document discusses persistent storage options for Kubernetes in production environments. It begins by explaining why state management can be tricky in containers due to lack of storage pets, data needing to follow applications, and human fallibility. It then compares different storage solutions based on CNCF principles like being application-centric, platform agnostic, API-driven and more. Finally, it examines the specific needs of a fictional user Jane for her WordPress sites and recommends suitable storage for each use case like databases, user uploads, backups and more. Software defined storage like StorageOS is presented as an optimal on-prem solution that provides high availability and horizontal scalability.
