Project Overview
Designed and implemented a secure, scalable three-tier architecture on AWS VPC to demonstrate infrastructure best practices for production-ready cloud environments. The project focused on network isolation, security, and automated scaling to handle variable workloads efficiently.
Key Features
- Secure Three-Tier Architecture: Implemented public and private subnets with proper network segmentation
- Network Security: Configured NAT gateways and security groups for controlled traffic flow
- Auto-Scaling: Set up AWS CloudWatch alarms to trigger auto-scaling based on traffic metrics
- Cost Optimization: Designed to optimize resource usage during both high and low traffic periods
Technical Implementation
- Created VPC with public and private subnets for different application tiers
- Configured NAT gateways for outbound internet access from private subnets
- Implemented security groups to control inbound and outbound traffic
- Set up auto-scaling groups with CloudWatch alarm triggers
- Designed for horizontal scaling to handle traffic spikes efficiently
Outcomes
- Demonstrated ability to design secure, production-ready AWS infrastructure
- Showcased understanding of auto-scaling principles and cost optimization
- Created a template for scalable three-tier web application architecture
