AWS – Serverless Digital Banking Platform
Discover how Unison helped a traditional commercial bank fast-track its digital transformation journey using AWS.
AWS – Serverless Digital Banking Platform
Client / Department
Our client was the Digital Banking Division of a leading commercial bank in Singapore. Faced with intense competition from fintech and neobanks, the bank sought to rapidly launch a fully digital banking platform. Traditional development models were too slow and costly to meet the market demands. They needed a flexible, scalable, and secure cloud-native solution to stay ahead.
Problems
The bank needed to launch a digital-first platform rapidly, but traditional development was too time-consuming.
- Slow deployment cycles hindered go-to-market speed.
- Rising infrastructure costs with no usage-based optimization.
- Limited scalability during high transaction periods.
- No integration support for open banking initiatives.
Solutions
Unison deployed a serverless architecture using AWS to meet speed, scalability, and compliance goals.
- Used AWS Lambda and API Gateway for event-driven processing.
- Built an API-first ecosystem for open banking compliance.
- Integrated AWS Cognito for secure customer identity management.
- Leveraged managed services to reduce infrastructure overhead.
