Challenges
- Fragmented Workspaces: IHT, AMC, and MRHFL environments functioned in isolation.
- Security Risks: Manual key management and shared cluster library vulnerabilities.
- Resource Inefficiency: Subnet exhaustion and lack of compute governance.
- Compliance Gaps: No native lineage or query auditing history.
Solutions
- UCX Migration: Automated transition of schemas, tables, and permissions.
- Identity Management: Switched to Azure Managed Identities for secure storage access.
- Compute Governance: Custom cluster policies to prevent resource sprawl.
- Databricks Volumes: Simplified management of shared files and secure library installations.
Outcomes
- 25-30% Reduction in projected storage costs.
- 3,800+ Tables & 70+ Jobs migrated with zero data loss.
- 15-20 Day Sprints for even the most complex workspace migrations.
- RBI-Compliant framework with fine-grained RBAC and automated lineage.
