THE CHALLENGE

A medical technology and healthcare services company was managing its Oracle database on a stack that was never designed for where the business was heading. This led to a set of compounding infrastructure problems that eroded efficiency and inflated cost over time.

For our client, the pain points included:

Licensing overhead with no strategic return. Running Oracle on Windows with Veritas meant carrying the cost of multiple licensed products that weren't delivering differentiated value. These weren't investments in capability; they were operational costs tied to a stack the organization had outgrown.
Legacy scripts that couldn't keep pace. Maintenance scripts written in Perl were increasingly difficult to support, particularly as the team evaluated a move toward Linux-based infrastructure. Incompatible tooling introduced operational risk and added friction to every maintenance cycle.
Limited scalability and reactive performance management. Without a cloud-native foundation, scaling Oracle workloads efficiently wasn't viable. Backup methods were expensive, performance tuning was reactive and the infrastructure couldn't support the organization's evolving data demands.

The client needed to:

Migrate Oracle databases off Windows and Veritas onto AWS
Replace licensed infrastructure with AWS-native services
Modernize the operational layer to reduce risk and improve maintainability
Build a scalable foundation without reintroducing unnecessary cost or complexity

The company selected EPAM, an AWS Premier Tier Services Partner, for this work due to its deep engineering expertise and cloud innovation.

THE SOLUTION

EPAM approached the engagement with a structured methodology, prioritizing stakeholder alignment, operational continuity and long-term maintainability from the outset.

KEY FEATURES

AWS-Native Architecture

Oracle workloads migrated to EC2 instances running Linux with Oracle Data Guard, replacing Windows and Veritas across the board.

Automated Deployment

Standardized, repeatable deployments with reduced human error and higher automation across the infrastructure layer.

Amazon S3 & AWS Backup Integration

Cost-effective, cloud-native backup methods replaced expensive legacy approaches, contributing directly to TCO reduction.

AWS Sync for Data Operations

High-reliability data transfer and synchronization across environments without disruption to live operations.

Script Modernization

Maintenance scripts converted to Python for improved compatibility, readability and long-term maintainability across Linux and Windows environments.

Performance Tuning & Team Enablement

Multiple performance tuning cycles delivered measurable infrastructure improvements, with findings shared directly with client application teams to build internal capability.
