Client Overview

Organization: Regional Medical Center (200-bed acute care facility)

Location: Southeastern United States

Annual Patient Encounters: 125,000+

IT Environment: Epic EHR, PACS imaging system, patient portal, laboratory information system, pharmacy system

The Challenge

Regional Medical Center faced aging on-premises infrastructure with their Epic EHR system hosted in a local data center. Hardware was reaching end-of-life, and the hospital faced a difficult decision: invest $2.5M in new on-premises infrastructure or migrate to the cloud.

Key challenges included:

  • Zero downtime requirement: Hospital operates 24/7 with critical patient care systems that cannot experience outages
  • HIPAA compliance: All patient health information (PHI) must remain secure and encrypted during migration
  • Integration complexity: Epic system integrated with 15+ clinical applications including PACS, lab, pharmacy
  • Remote physician access: 50+ physicians required secure VPN access from homes and satellite clinics
  • Data volume: 2.8TB of patient records spanning 15 years

Our Solution

We designed and executed a phased Azure migration strategy leveraging our Microsoft Gold Partner status and Epic-certified cloud expertise. The approach eliminated the need for capital expenditure while improving performance and disaster recovery capabilities.

Architecture Design

  • Azure Virtual Machines: Epic production, non-production, and cache servers on compute-optimized VMs
  • Azure SQL Database: Chronicles database with geo-replication for disaster recovery
  • Azure Blob Storage: Medical imaging and document storage with lifecycle management
  • ExpressRoute: Dedicated 1Gbps Azure connection for low-latency access
  • Azure VPN Gateway: Secure remote access for physicians and staff
  • Azure Security Center: Continuous compliance monitoring and threat detection

Migration Phases

Phase 1: Assessment & Planning (Week 1-2)

Infrastructure discovery, application dependency mapping, network baseline, and Azure sizing recommendations

Phase 2: Azure Foundation Build (Week 2-3)

ExpressRoute provisioning, network configuration, identity integration with Active Directory, security controls

Phase 3: Non-Production Migration (Week 3-4)

Test and training environments migrated, application testing, performance validation

Phase 4: Production Cutover (Week 5-6)

Weekend production migration using database replication and synchronized cutover. Zero patient care disruption.

Sarah Johnson, CTO
Regional Medical Center

"Realistic Electronic Solutions transformed what could have been a catastrophic project into our smoothest technology initiative in years. Not a single patient experienced service interruption. Our clinicians didn't even realize the migration happened until we told them it was complete. The cost savings alone justified the project, but the performance improvements and disaster recovery capabilities have positioned us for future growth. I cannot recommend their team highly enough."
