Hadoop HDP to CDP Migration: Modernization and Security of a Hospital Information System
David Walter • 6 novembre 2025
Project Context
A hospital center needed to modernize its Big Data infrastructure. Its Hadoop HDP environment was reaching end-of-support and showed technical limitations in both performance and security.
The complexity of the hospital’s IT system — including electronic medical records, patient management systems, and telemedicine platforms — required a carefully managed migration, ensuring the continuity of patient care without disruption.
Objectives
The main goal was to ensure a smooth and secure transition to Cloudera Data Platform (CDP) in order to:
- Improve performance and security of critical systems
- Ensure compliance with healthcare regulations
- Reduce operating costs while modernizing the Data environment
Mission Duration
A multi-month project, structured around diagnostic, migration, and production phases, followed by post-migration support.
Implementation
To deliver this strategic migration successfully, Agaetis deployed a rigorous methodology:
- Audit and planning: Analysis of the existing HDP environment and identification of data to migrate
- Migration plan: Definition of required resources, timeline, and organization of key steps
- Execution: Transfer of data, metadata, workflows, and applications to CDP with optimized configuration
- Validation tests: Verification of data integrity and post-migration performance
- Optimization & production: Fine-tuning for maximum performance and user training on CDP’s new features
Results Achieved
- Increased performance: Faster, more stable critical systems
- Enhanced security: Regulatory compliance ensured for managing sensitive medical data
- Cost reduction: 10% decrease in operating costs, representing annual savings of €100,000 on a €1M budget
- Continuity of care maintained: Migration completed with zero service interruption
Key Success Factors
- Agaetis’ expertise in complex Big Data migrations
- Secure, phased approach tailored to sensitive hospital environments
- Transparent communication with the client’s IT teams
- Comprehensive training and knowledge transfer for end users
