Dynamic Provisioning in Kubernetes with Portworx StorageClasses enables automatic, on-demand creation of storage volumes as requested by applications through Persistent Volume Claims (PVCs). This eliminates the need for administrators to manually create and manage volumes, significantly improving operational efficiency and accelerating application deployment. StorageClasses encapsulate parameters such as replication, encryption, and IO profiles, ensuring consistent volume configuration. Dynamic Provisioning also supports scaling and workload agility by provisioning storage transparently based on application needs. This feature is central to cloud-native storage management and is well documented in both Kubernetes and Portworx installation guides. It contrasts with manual volume creation, which is labor-intensive and error-prone, thus dynamic provisioning enhances automation and simplifies storage lifecycle management【Pure Storage Portworx Kubernetes Guide†source】.

Skinny Snapshots are a space-efficient snapshot technique used by Portworx for replicated volumes (Repl 2 or 3) when storage capacity is limited and no external Object Store is configured. Unlike full snapshots that duplicate data blocks, skinny snapshots capture only the differences (deltas) since the last snapshot, minimizing space consumption. This method allows administrators to take frequent snapshots without significantly impacting storage availability. Skinny Snapshots are particularly useful for on-premises environments or clusters without access to cloud object storage, balancing snapshot granularity with resource constraints. Official Portworx snapshot documentation explains how skinny snapshots work internally, improving backup and recovery capabilities under tight storage conditions without requiring cloud integration【Pure Storage Portworx Snapshot Guide†source】.
