ENTERPRISEARCHITECTURE
Comprehensive enterprise architecture showcase featuring infrastructure, security, and platform design patterns built on an open reference platform.
This environment serves as my Open Systems Reference Platform — a living laboratory where I design, validate, and demonstrate enterprise-class architecture patterns across networking, security, virtualization, and automation domains using modern, cost-effective technologies.
🔒 Micro-Segmentation Security Architecture
Enterprise-grade network isolation with 22 VLANs across 8 security zones
Why 22 VLANs? Strategic Network Isolation
Zero Trust Architecture
Every network segment operates under "never trust, always verify" - preventing lateral movement during breaches.
Blast Radius Containment
Compromised devices are contained within their VLAN, unable to access critical infrastructure or spread malware.
Granular Traffic Control
Precise firewall rules control which services can communicate, reducing attack surface by 95%+.
Enhanced Monitoring
Detailed visibility into network flows enables rapid threat detection and forensic analysis.
Core Infrastructure
Highest security tier - infrastructure management and admin access
Virtualization Layer
Isolated hypervisor and storage networks - no external access
Identity & Access Management
Domain services with controlled internet access via proxy
Security Services
Security monitoring and threat intelligence - direct internet for updates
Server Infrastructure
Application servers with controlled outbound access
Endpoint Devices
User devices with content-filtered internet access
Guest Networks
Isolated guest access with direct internet but no internal access
WAN / Internet
External internet connection and gateway - the source of all outbound traffic

�️ Enterprise Architecture Principles
Defense in Depth: Palo Alto firewall provides L3 routing and security between Internet and internal networks, with UniFi handling L2 VLAN segmentation.
Hierarchical Design: Clean three-tier architecture from Internet → Security → Distribution → Access, ensuring scalability and manageable complexity.
VLAN Segmentation: Logical separation of network traffic by function (trusted devices, IoT, guest, lab) with appropriate inter-VLAN routing policies.
Enterprise Features: PoE distribution for cameras and APs, centralized UniFi management, and redundant uplinks for high availability.
