Secure Payment Processing System Architecture on AWS
🔗 https://tannu610.github.io/PayShield/
PayShield is an interactive AWS cloud architecture visualization that demonstrates how a secure, production-style payment processing system can be designed using modern cloud infrastructure principles.
The project focuses on:
- High Availability
- Secure Network Design
- Multi-AZ Deployment
- Private Subnet Isolation
- Load Balancing
- Database Failover
- Monitoring and Observability
- Amazon VPC
- Internet Gateway
- Public & Private Subnets
- Multi-AZ Architecture
- EC2 Backend Instances
- Bastion Host
- Auto Scaling Ready Design
- Application Load Balancer (ALB)
- HTTPS Request Handling
- Amazon RDS
- Multi-AZ Replication
- Private DB Subnets
- Amazon CloudWatch
- Logs, Metrics, and Alarms
- Security Groups
- Least-Privilege Access
- Private Application Layer
- Restricted SSH Access
Users send HTTPS requests through the Internet Gateway to the Application Load Balancer.
The ALB distributes traffic across backend EC2 instances running in private subnets.
Application servers securely communicate with Amazon RDS inside isolated database subnets.
Responses are securely returned back to users through the ALB over HTTPS.
- EC2 instances are not publicly accessible
- Database instances remain isolated in private DB subnets
- Security Groups enforce least-privilege communication
- SSH access is restricted through a Bastion Host
- Only ALB can communicate with backend EC2 instances
- Only backend servers can access the database
- Interactive request flow visualization
- Step-by-step traffic tracing
- Multi-AZ infrastructure representation
- Production-style AWS architecture
- Modern responsive UI
- Security-focused infrastructure design
- HTML5
- CSS3
- JavaScript
- AWS Architecture Concepts
- GitHub Pages
