Cloud Migration: A Guide for Hospitals
Hospital information systems today face multiple challenges: increasing needs for flexibility, exponential data volumes, cybersecurity imperatives, and constant cost optimization. In this context, cloud computing is increasingly becoming an indispensable solution for modernizing and simplifying IT infrastructure in hospitals.
However, migrating to the cloud cannot be improvised. This guide explains why hospitals should consider cloud computing, the types of solutions available, points of vigilance before migration, essential steps for a successful project, and proposes a practical case study.
Why Consider Cloud Computing in Hospitals?
- Reducing Infrastructure Costs
Cloud computing limits heavy investments in hardware (servers, storage) and transforms expenses into predictable and adjustable costs based on consumption. - Access to Innovative Services
Big data, artificial intelligence, machine learning: cloud computing facilitates the integration of advanced technologies for analyzing medical data, automation, and developing diagnostic tools. - Resilience and Business Continuity
Cloud computing ensures high availability of services and rapid recovery in case of incidents, thanks to robust backups and redundancy.
Types of Clouds Suitable for Hospitals
- Private Cloud Dedicated environment, hosted on-site or by a provider. Maximum control and enhanced security, but high costs and management.
- Public Cloud Shared platforms (Azure, AWS, OVH): varied services and competitive pricing, but requires HDS certification for hosting health data.
- Sovereign HDS Cloud French solutions certified HDS (IDS, Outscale…): maximum compliance with legislation, secure management of sensitive data.
Points of Vigilance Before Migrating
- HDS Certification of the Provider Ensure that the hosting provider is HDS certified and complies with ISO 27001 and GDPR standards for health data security and compliance.
- Data Reversibility The contract must guarantee easy data recovery in case of a change of provider, with precise clauses on restitution and performance (SLA).
- Adaptation of Contracts and SLA Demand strong commitments on availability, security, and speed of service recovery, adapted to the critical requirements of the hospital sector.
Steps to Successfully Migrate to Cloud in Healthcare
- Conduct an Audit of Existing Infrastructure
Identify and map all sensitive data, applications, and flows. Classify information according to its criticality and regulatory compliance. - Analyze Feasibility and ROI
Evaluate direct and indirect costs, expected benefits in terms of agility, security, and operational efficiency. - Plan Migration in Phases
Adopt a progressive approach: start with non-critical applications, test each batch before proceeding to minimize risks. - Conduct Thorough Tests
Before the final switch, verify security, service continuity, and compliance. Identify and correct any potential incidents. - Support Change Management
Train teams, communicate the benefits, and involve all stakeholders from the beginning for a successful adoption.
Plan for Change Management: support users, anticipate resistance, and plan targeted training.
Migrating to the cloud is a key step in modernizing hospitals and alleviating their technical and economic constraints. However, this project must be carried out methodically:
- Prefer HDS-certified providers.
- Follow a rigorous and progressive planning process.
- Impose strict criteria for data security and reversibility.
By investing in this digital transformation, you pave the way for a more agile organization prepared to face modern healthcare challenges.
