Station

Architecture & Platform Decisions

Use requirements and constraints to select the implementation style, architecture pattern, and enabling platform capabilities.

Architecture choices should follow from evidence about business impact, locations, trust boundaries, capacity, latency, data ownership, consistency, operability, security, privacy, governance, and cost.

  • Clear rationale for API, event, file, stream, data product, direct integration, or hybrid implementation style

Journey criteria

Entry criteria

  • Capability opportunity is identified and documented.
  • The capability addresses a clear business need and is reusable by its intended consumers.
  • The selected interface provides an appropriate abstraction for consumers.
  • The capability value proposition has been validated with business and consumer stakeholders.
  • Consumer segments are identified.
  • A high-level implementation roadmap is defined.

This is what success looks like

Compare viable architecture styles against the gathered requirements and document the selected pattern and rationale.

  1. Use the Business Impact Canvas to identify availability, security, and data risks that influence architecture options. — Business Impact Canvas
  2. Use the Locations Canvas to capture geopolitical, regulatory, network, residency, and trust-boundary constraints. — Location Canvas
  3. Use the Capacity Canvas to capture current and future volumes, peaks, latency, caching, rate limiting, and scaling expectations. — Capacity Canvas
  4. Use metrics and analytics guidance to define how the chosen capability will be monitored and improved.

Resources for Architecture & Platform Decisions

canvas

Business Impact Canvas

Identify business, availability, security, data, compliance, and operational risks that should shape architecture and platform decisions.

Outcomes

  • Documented business and operational impact assessment
  • Prioritized risks and mitigation actions
  • Evidence for architecture and platform decisions

How it works

  1. Availability Risks: Identify risks and impacts.
  2. Ways to Mitigate Availability Risks: Define mitigation measures.
  3. Security Risks: Document security-related risks.
  4. Ways to Mitigate Security Risks: Propose strategies to mitigate security risks.
  5. Data Risks: Identify risks to data accuracy or availability.
  6. Ways to Mitigate Data Risks: Plan strategies to address data risks.
