This repository documents my work in the 2025 Networking Fundamentals Bootcamp. I intentionally diverged from the standard demo project to design a custom cloud-native architecture that demonstrates all required networking fundamentals through an enterprise-style AI orchestration system.

A zero-trust, multi-agent system designed for enterprise AI workflows across isolated VPCs.
Key networking principles demonstrated:
- VPC Isolation — Brown (Public VPC) and Bayko (Private VPC)
- Cross-VPC Communication — via S3 and EventBridge
- Zero Trust — No direct communication between agents
- IAM Role Separation — Scoped permissions for all agent roles
- Event-Driven Architecture — Asynchronous task processing with traceability
This project demonstrates real-world implementation of core networking fundamentals through a secure, zero-trust, multi-agent system architecture.
| Bootcamp Topic | My Implementation |
|---|---|
| VPC Design | Dual-VPC layout (10.0.x.x / 10.1.x.x) |
| Firewall Rules | Security groups with Layer 4 isolation |
| IP Address Management | Subnets with clear CIDR allocations |
| NAT Gateway | NAT for outbound-only traffic in public tier |
| Load Balancer | ALB routes traffic to Agent Brown |
| Network Monitoring | CloudWatch logs + output metrics |
| Traffic Flow | EventBridge + S3 coordination |
| Zero Trust Architecture | No runtime agent-to-agent communication |
- Agent Brown (Public VPC): Input validation, tagging, routing
- Agent Bayko (Private VPC): Tool orchestration, processing, output assembly
- S3 Communication Bridge: Message handoff between agents
- EventBridge Orchestration: Decoupled agent triggers
- CloudFront CDN (Optional): Secure delivery of artifacts
This project fulfills all required networking fundamentals through real infrastructure:
- VPC/Subnet design
- Firewall configuration and SG rules
- Cross-network service coordination
- Load balancer integration
- Event-driven communication
- Monitoring and observability
- Zero-trust implementation
- Designed and documented multi-agent network architecture
- Applied zero-trust design to AWS cloud networking
- Implemented asynchronous orchestration using S3 + EventBridge
- Demonstrated production-grade isolation and security patterns
- Mapped bootcamp topics to real-world infrastructure
