SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill guides architects and engineers to organize deployment infrastructure into a clear, maintainable set of tiers (DMZ → AppTier → ProcTier → DataTier) with explicit parent-child relationships and firewall boundaries between zones.

Core Features & Use Cases

  • Establish a standard 4- to 5-tier reference pattern (DMZ, AppTier, ProcTier, DataTier) with optional SecZone and InfraZone extensions.
  • Define per-tier responsibilities, service layouts, and inter-tier firewall rules to enforce security boundaries.
  • Provide a reusable blueprint for documenting deployment architectures and guiding secure infrastructure design across teams.

Quick Start

  • Start by mapping your environment to the Environment → Tier structure, assign services to each tier, and draft firewall rules that describe allowed traffic between adjacent zones.

Frequently Asked Questions about structure-deployment-tiers

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I structure deployment tiers for secure infrastructure design?▼

Structure deployment tiers by organizing infrastructure into a hierarchical set of DMZ, AppTier, ProcTier, and DataTier with explicit parent-child relationships and firewall boundaries to enforce security zones.

What is the standard reference pattern for tiered deployment architecture?▼

The standard tiered deployment architecture uses a 4- to 5-tier reference pattern including DMZ, AppTier, ProcTier, and DataTier, with optional SecZone and InfraZone extensions for specialized services.

How do I define firewall rules between DMZ and AppTier environments?▼

Define firewall rules between DMZ and AppTier environments by using a standard template that documents allowed traffic and inter-tier communication rules across adjacent zones for secure boundaries.

How should I assign services to infrastructure tiers during environment modeling?▼

Assign services to infrastructure tiers by mapping your environment to the Environment → Tier structure, defining per-tier responsibilities, and placing services into the DMZ, AppTier, ProcTier, or DataTier accordingly.

Can I use tier mapping for documenting deployment architecture across teams?▼

Yes, you can use tier mapping for documenting deployment architecture across teams by applying a reusable blueprint that provides consistent tier definitions, service placement, and inter-tier communication rules.
