| Persistent Volume Claims (PVCs) | Used to request storage resources from a cluster. PVCs are similar to PVs but do not create actual storage; instead, they create a reference to storage that can be consumed by pods. When a PVC is created, k8s automatically provisions a matching PV. PVCs decouple storage consumption from storage provisioning, making it easier to manage storage resources | - Decouples storage consumption from provisioning - Requests storage resources from a cluster - Automatically provisions a matching PV when created |
- Applications with variable storage needs: PVCs are useful for applications whose storage requirements change frequently - Applications requiring flexible storage: PVCs allow developers to request specific amounts of storage without worrying about managing underlying PVs |
- Use PVCs when storage requirements are unknown or dynamic - Specify appropriate storage sizes for PVCs based on application needs - Monitor PVC usage to avoid over-provisioning or under-provisioning storage resources |
