Storage considerations

To run stateful applications, developers need to store the persistent data in managed storage that is backed by some physical storage. Persistent volumes allow a state to persist across pods.

About this task

When you investigate the storage options for a deployment, consider everything in the whole, including the network, licenses, replication, and cost.

Attention: CP4BA production deployments often need high performance, so do not use open source storage providers like the Kubernetes NFS-Client Provisioner for your production deployments. Use Container Storage Interface (CSI) drivers from platform-providers like IBM Storage Fusion, AWS EFS, Azure Files, and others. For more information, see Storage options.
