Networking Fundamentals Bootcamp 2025 — Custom Architecture Track

Instructor: Andrew Brown & Tim McConnaughy

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.

🧠 Architecture at a Glance — Secure Multi-Agent 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

🔍 Networking Principles in Practice

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

🧱 Core Components

• 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

---

✅ Compliance Summary

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

---

🧠 Learning Highlights

• 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
