Architecture Zoning Map

A one-page map of the technology estate as a city plan: zones, integration roads, shared utilities and no-build rules.

First page of Architecture Zoning Map

What's inside

  • Six architecture zones, each with a purpose and example services: customer engagement, core business, data and analytics, shared services, infrastructure, and a no-build zone for bought capabilities.
  • Integration roads: four patterns and when to use each, with direct database access between zones prohibited.
  • Shared utilities every service must use, such as the identity provider, API gateway and secret manager.
  • No-build rules, each with its rationale.
  • The PowerPoint version has two slides: the zones and the roads and rules.

Format: PDF (3 pages) and PowerPoint file.

How to use it

Replace the sample zones and services with your own and give the map to teams as the rules for building new services.
