Case Study
Enterprise Architecture for a 1000-Bed Smart Hospital Digital Platform
Designed the end-to-end enterprise architecture for a 1000-bed smart hospital, covering data center strategy, hybrid cloud integration, network architecture, zero-trust security, and disaster recovery with zero data loss and sub-45-minute recovery.
Overview
Defined the complete enterprise architecture covering infrastructure, network, security, disaster recovery, and hybrid cloud integration for a 1000-bed hospital, balancing clinical reliability, performance, and scalability.
Business Context
Designed a clinically safe, resilient, and secure technology platform for a large-scale hospital environment, ensuring uninterrupted patient-critical system performance while supporting advanced capabilities such as robotic surgery and global healthcare integrations.
Challenge
The architecture required zero tolerance for downtime, ultra-low latency for critical systems, secure integration with global healthcare partners, and the ability to handle catastrophic failure scenarios without impacting patient safety.
Architecture Approach
Adopted a hybrid enterprise architecture with Tier IV primary data center, Tier III disaster recovery site, 100G dark fiber for synchronous replication, multi-cloud active-active for public systems, and segmented network architecture aligned to clinical criticality.
Key Architecture Decisions
Selected Active–Hot Standby DR model to eliminate split-brain risk, used 100G dark fiber for RPO=0 replication, implemented Zero Trust security across layers, separated workloads based on clinical criticality, and adopted multi-cloud only for non-clinical workloads.
Trade-offs and Considerations
Higher infrastructure investment for guaranteed clinical safety, increased complexity due to hybrid architecture, and strict workload segregation reducing flexibility but significantly improving reliability and risk posture.
Outcome
Achieved zero data loss (RPO=0), recovery within 45 minutes (RTO≤45min), enabled zero-downtime operations, and delivered a scalable, future-ready enterprise architecture aligned with clinical safety requirements.
