Get more out of massive on-prem data using modern Databricks Data Intelligence Platform. Explore our Storage ecosystem, fueled by open source OpenSharing.

Tier-1 banks have adopted "Hybrid Forever" strategies, modernizing on-premises storage while maintaining strict data sovereignty. Major pharmaceutical companies run millions of daily drug experiments against petabyte-scale on-premises data estates subject to stringent regulatory controls.
