Digital Transformation Case Study on AWS

This case study outlines the digital transformation of a client's infrastructure and database management by migrating from on-premise systems to Amazon Web Services (AWS). The client aimed to control infrastructure and licensing costs while reducing manual intervention in backup management and ensuring high availability as their business scaled. The migration involved transitioning a third-party licensed database serving approximately 40 applications to Aurora PostgreSQL on AWS, utilizing a re-platform cloud migration strategy. The application code was deployed on AWS EC2 Windows instances through a lift and shift migration strategy. Post-migration, maintenance activities such as database backups and server patching were automated. Security measures were implemented following AWS best practices, including AWS Security Hub and AWS GuardDuty. The migration resulted in a significant reduction in licensing costs and improved application availability by approximately 50%. This case study serves as a reference for organizations in the healthcare and life sciences sector considering similar cloud migration strategies.
