Barrett Values Centre (BVC), a global leader in organizational development, relied on an aging monolithic system built on Java 6. As business needs evolved, their legacy system became a bottleneck, limiting scalability, security, and performance while increasing maintenance efforts. The inability to integrate with modern cloud services and the complexity of adding new features led to inefficiencies.

“ I was blown away by their systematic approach to helping clients like myself to meet their goals. The great thing about Code District is that they do embrace industry standards in terms of methodology which includes retrospectives, so they are very good at making adjustments to what is working well and what can be improved with each client.”

BVC’s transition from Java 6 was driven by several key challenges that hindered growth, security, and performance:
Java 6 lacked modern security features, making it vulnerable to cyber threats and non-compliant with GDPR and industry regulations. It also restricted integration with modern frameworks and cloud services, limiting scalability.
The system was tightly coupled, making even minor changes risky and time-consuming. It could not scale efficiently, and traffic spikes during survey periods caused performance slowdowns and system outages.
The lack of modular architecture led to long development times. Rolling out new features or bug fixes required changes across the entire system, increasing complexity and the risk of breaking existing functionalities.
The legacy system was not optimized for cloud deployment, preventing the use of auto-scaling, containerization, and cost-effective cloud services. Hosting on outdated infrastructure resulted in higher operational costs.
The monolithic database schema caused data inconsistencies, slow query performance, and maintenance difficulties. The system struggled to efficiently process high volumes of survey and reporting data, impacting response times.
To address these challenges, we implemented a modernization strategy that transformed BVC’s legacy system into a scalable, high-performance, and secure platform:

Refactoring the monolithic architecture into microservices allowed for independent scaling, faster deployments, and improved maintainability. Key modules (Reporting, Survey, and Integration) were decoupled to enhance flexibility.
Deploying the system on AWS introduced auto-scaling, containerization, and cloud-native optimizations. Implementing AWS ECS, RDS, and S3 ensured that BVC could handle traffic surges, improve response times, and reduce infrastructure costs.
We integrated Spring Security, OAuth2, and JWT authentication to improve access control and data encryption. AWS security services such as IAM policies, WAF, and automated compliance monitoring helped BVC achieve full GDPR compliance.
The adoption of CI/CD pipelines using Bitbucket, CodeBuild, and CodeDeploy accelerated deployments by 60%, reduced manual intervention, and improved software reliability through automated testing and monitoring.
The old monolithic database schema was redesigned for microservices compatibility, enabling faster queries, real-time analytics, and structured data processing. A data synchronization mechanism ensured a smooth transition with zero data loss.
