Station

API Platform Architecture

Ensure scalability, reuse, and governance across your API and platform components.

When APIs scale across teams, your platform must enable governance and reuse without blocking speed. This station shows how to architect APIs for longevity, security, and efficiency.

This is what success looks like

Establish a scalable, secure, and compliant infrastructure for API operations. Provide guidelines on architecture best practices.

  1. The Business Impact Canvas helps to identify and mitigate risks related to API availability, security, and functionality to support informed architectural decisions. — Business Impact Canvas
  2. Map the regulatory, compliance, and network locations of API providers and consumers to ensure accessibility and compliance. — Location Canvas
  3. The Capacity Canvas aligns business transaction patterns, future consumption trends, and technical solutions to ensure API scalability and performance.It provides critical input for scaling decisions and infrastructure planning. — Capacity Canvas
  4. Define and monitor performance metrics (e.g., API calls, latency, error rates) and adoption metrics (e.g., NPS).

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.
