Kubernetes-Based Fintech Infrastructure on AWS
Overview
Designed and managed a cloud-native AWS infrastructure for a fintech platform requiring high availability, secure deployments, and automated scaling.
Client Background
Confidential fintech product handling user transactions and requiring secure, reliable infrastructure.
The Challenge
The platform required:
- Reliable containerized deployment
- Secure networking
- Automated CI/CD
- Scalable Kubernetes cluster
- Observability and monitoring
Architecture Overview
Users
→ AWS ALB
→ Kubernetes Cluster (EKS)
→ API Pods
→ Worker Pods
→ RDS
→ S3
→ Prometheus + Grafana
Implementation Approach
Infrastructure Provisioning
- Used Terraform for AWS resource provisioning
- Created VPC, subnets, security groups
- Configured EKS cluster
Containerization
- Built Docker images
- Managed Docker networks and volumes
- Pushed artifacts via CI pipeline
CI/CD Automation
- Integrated GitHub → Jenkins → Kubernetes
- Automated container builds and deployments
- Implemented rollback capability
Monitoring
- Implemented Prometheus monitoring
- Built Grafana dashboards
- Configured alerts for cluster health
