Client challenge

Our client encountered major limitations with their Oracle-based application platform, which was heavily dependent on PL/SQL. The monolithic architecture posed scalability issues and slowed down feature updates. Furthermore, the reliance on on-premises infrastructure led to operational inefficiencies and restricted the platform’s ability to effectively support third-party subscribers. To address these challenges, Schreiber aimed to transform the platform into a flexible, modern SaaS solution capable of supporting future growth and adapting to changing business requirements.

Our solution

To solve the client’s challenges, we migrated from a monolithic Oracle platform to a flexible, microservices-based architecture on AWS. The modernization focused on utilizing serverless technologies and included the following components:

Serverless Architecture: AWS Lambda and API Gateway were implemented to establish a cost-efficient and scalable serverless environment.
Containerized Services: Amazon EKS and Fargate managed microservices, improving scalability and simplifying application deployment.
AI-Assisted Code Migration: Legacy PL/SQL code was rewritten in Python with the help of generative AI tools like Q for Developer and Co-Pilot, speeding up the transformation process.
Modular Product Architecture: The platform was restructured into a modular design, enabling quicker development, simpler updates, and better third-party integrations.
Future Database Optimization: The Oracle database will be migrated to Amazon Aurora to boost performance and reduce operational complexity.

Results

The project provided considerable operational and business advantages, such as:

Scalability: Transitioned to a serverless architecture, decreasing infrastructure management workload by 40%.
Accelerated Time to Market: Modular design enhanced feature development speed by 50%.
Cost Efficiency: Operational expenses were reduced by 30% with serverless computing and optimized resource utilization.
Improved Agility: The updated platform now accommodates both internal users and third-party subscribers, unlocking new business possibilities.
