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 .
Insights on Cloud Transformation
How do you achieve zero downtime?
We use traffic-shifting techniques like Blue-Green or Canary deployments. By keeping the old environment active until the new one is fully validated, we ensure seamless transition with no interruption.
Is AWS the only cloud you support?
While this case study focuses on AWS, we also have extensive expertise in Azure and Google Cloud Platform (GCP), tailoring the environment to your specific regional and cost requirements.
