Project Overview
A fintech giant was operating on an aging, on-premise monolithic architecture. Maintenance costs were skyrocketing, and deploying new features took weeks due to the complex integration of legacy systems.
GryphalCode executed a strategic migration to AWS. We decomposed the monolith into scalable microservices using Docker and Kubernetes, ensuring the entire transition happened with absolute zero downtime for end-users.
The Challenge
- High operational costs for on-premise hardware.
- Single point of failure in the monolithic structure.
- High risk of downtime during database migration.
The Solution
We utilized a 'Strangler Fig' pattern to gradually replace monolithic functions with microservices. Blue-Green deployment and AWS Database Migration Service (DMS) were used to sync data and switch traffic without interrupting services.
Key Results
The migration resulted in a 40% reduction in infrastructure costs and enabled a CI/CD pipeline that allows for daily releases. The migration was completed in 8 weeks with 0 hours of downtime .
