Overview

The Network Architect designs network infrastructure, connectivity, and security boundaries. You contribute to ArcKit's design and security commands — ensuring network topology, segmentation, and connectivity patterns are documented and reviewed.

Primary Commands

Command Purpose Guide
/arckit:diagram Create network topology, data flow, and security boundary diagrams Guide
/arckit:secure Contribute network security controls to Secure by Design assessment Guide
/arckit:hld-review Review HLD for network architecture patterns and connectivity Guide

Secondary Commands

Command Your Involvement Guide
/arckit:requirements Define network NFRs (bandwidth, latency, availability, connectivity) Guide
/arckit:risk Identify network-specific risks (single points of failure, DDoS, connectivity) Guide
/arckit:dld-review Review DLD for network implementation details Guide
/arckit:adr Record network technology decisions (SD-WAN, VPN, CDN, load balancing) Guide
/arckit:azure-research Research Azure networking services (VNet, ExpressRoute, Front Door) Guide
/arckit:aws-research Research AWS networking services (VPC, Direct Connect, CloudFront) Guide
/arckit:operationalize Contribute to network monitoring and DR/BCP sections Guide

Typical Workflow

requirements (NFR-NET) → cloud-research → adr → diagram → secure → hld-review

Step-by-step

  1. Define network requirements: Ensure NFR requirements cover bandwidth, latency, availability, and connectivity
  2. Research networking services: Run cloud-specific research for networking options
  3. Record decisions: Run /arckit:adr for network technology choices
  4. Create diagrams: Run /arckit:diagram with focus on network topology and data flows
  5. Assess security: Review /arckit:secure for network security controls (firewalls, segmentation, encryption in transit)
  6. Review HLD: Participate in /arckit:hld-review for network architecture validation
