Healthcare ISV Boosts Performance 25% with AWS Migration

Business Challenge

A leading enterprise healthcare ISV that powers the supply chain for many healthcare facilities needed to migrate mission-critical Oracle databases off aging on-premises Linux infrastructure to AWS. These databases could no longer keep pace with growing data volumes, high-demand workloads, or the real-time processing requirements their platform demanded.

Three core risks were driving urgency:

• Scalability constraints: The on-premises environment lacked the elasticity to support the client’s expanding healthcare supplier network.
• Compliance exposure: Enforcing HIPAA and GDPR standards on legacy infrastructure required significant manual effort and introduced audit risk.
• Capital cost burden: Ongoing investment in physical hardware was unsustainable.

The migration had to meet strict HIPAA compliance requirements, maintain continuous availability for healthcare supply chain operations, and position the client for long-term cloud scalability. Any migration also had to ensure zero disruption to the medical supply chain — an operational requirement with direct patient care implications.

Datavail’s Solution

Datavail migrated the client’s Oracle databases to EBS-Optimized Amazon EC2 instances — selected over Amazon RDS to preserve full OS-level control and maintain existing Oracle configurations, including Transparent Data Encryption (TDE) and Data Guard.

Our migration approach included:

• Oracle RMAN enabled efficient transfer of large database volumes.
• Oracle Data Guard maintained real-time replication between the on-premises primary and the AWS standby over a secure hybrid connection, with continuous redo transport throughout the transition.
• Amazon VPC with AWS IAM and VPC Flow Logs enforced HIPAA-compliant network security and access controls.
• AWS Backup enabled automated cross-region snapshots and point-in-time recovery, with Oracle RMAN providing additional protection.
• Amazon CloudWatch and Datavail TechBoost™ handled real-time performance observability and proactive alerting post-migration.
• TDE and centralized audit logging were implemented to simplify ongoing HIPAA and GDPR compliance enforcement in the new cloud environment.

Business Impacts

• Near-zero migration downtime: The controlled Oracle Data Guard switchover reduced cutover from an 8-hour offline baseline to a near-zero downtime event — significantly below the 15-minute target.
• 25% faster transaction processing: Migrating to EBS-Optimized EC2 instances improved database transaction speed by 25%, exceeding the initial 20% performance improvement target.
• Strengthened compliance posture: TDE and centralized audit logging simplified HIPAA and GDPR enforcement, reducing compliance risk on modernized cloud infrastructure.
• Continuous supply chain availability: Oracle Data Guard replication across AWS Availability Zones — paired with AWS Backup and RMAN — ensures near-zero RTO and zero RPO (recovery point objective) for ongoing operations.
• Modernization Readiness: The cloud migration positioned the client for future state architecture improvements such as cloud-native automation and modern data analytics.
