FinCore is a financial technology company providing solutions for online payments, transaction analytics, and accounting automation. As the client base and data volume grew, the existing infrastructure faced performance bottlenecks, and API response times nearly doubled.
Project Goal
To design a scalable and secure cloud infrastructure that ensures stable service operation, fast financial data processing, and enterprise-level transaction security.
What Was Done
- Migration to AWS Cloud:
Migrated all microservices from on-premise servers to AWS (EC2, S3, RDS), implementing load balancing and high availability. - Containerization & Orchestration:
Rebuilt the backend with Docker and Kubernetes, enabling automated deployment and dynamic scaling under load. - CI/CD Automation:
Set up pipelines using GitHub Actions and AWS CodePipeline for continuous integration and zero-downtime deployment. - Security & Encryption:
Configured IAM roles, AWS KMS encryption, and secure log storage with CloudWatch for compliance and data protection. - Monitoring & Alerting:
Integrated Prometheus, Grafana, and ELK Stack for real-time metrics, logs visualization, and automated alerts. - Cost Optimization:
Implemented auto-scaling and serverless components, reducing infrastructure costs by over 40%.
