Overview

MedSys HealthTech, a healthcare software provider in North America, was running its patient management and analytics solutions on Microsoft Azure. However, they faced limitations with cost optimization, vendor lock-in, and scalability during peak usage. With HIPAA compliance requirements and a rapidly growing customer base, MedSys needed a more flexible and cost-efficient infrastructure. MedSys approached Bacancy to develop and implement a structured Azure to AWS migration strategy, ensuring zero downtime, rational agility, achieving compliance, and significantly reducing infrastructure costs.

Challenges & Solutions

Vendor Lock-in with Azure Services

  • Solution: OurAWS migration consultants re-architected applications using AWS-native services such as Elastic Beanstalk and Lambda, removing dependency on Azure-specific services. This improved portability, reduced costs, and aligned with MedSys’s long-term cloud flexibility goals.

Ensuring HIPAA Compliance During Migration

  • Solution: Bacancy implemented AWS KMS encryption, private VPCs, IAM role-based access, and CloudTrail audit logging to ensure compliance. All sensitive healthcare data was encrypted in transit and at rest.

Database Migration Without Downtime

  • Solution: Using AWS DMS and a blue-green deployment approach, we migrated patient records and medical data with zero downtime. Data validation and integrity checks ensured no data loss

Handling Peak Traffic & Scalability

  • Solution: Applications were containerized and deployed on AWS EC2 with auto-scaling groups. Combined with CloudWatch monitoring, this ensured the system scaled seamlessly during patient portal traffic spikes.
