🔍 Frequently Asked Questions (FAQ)
1. What are key topics in modern API design?
Modern API design includes effective design and governance practices, integration of AI services via APIs, serverless and event-driven design principles, and patterns tailored for microservices architectures. These approaches ensure scalability, usability, and resilience.
2. What are best practices for API design and governance?
Best practices for API design and governance include treating APIs as products, applying consistent design methodologies, and enforcing documentation standards. Automation and collaboration help maintain quality, security, and long-term usability across the API lifecycle.
3. What does AI integration with APIs involve?
AI integration with APIs involves exposing AI services in ways that are scalable, intuitive, and performant. Strong documentation, robust data handling, and support for large language models (LLMs) are essential to ensure developers can effectively build AI-powered applications.
4. What are the principles of serverless and event-driven API design?
Serverless API design leverages cloud-native services to improve scalability and cost efficiency, while event-driven design focuses on building modular APIs that respond to asynchronous events. Together, these principles enable flexible, resilient, and efficient architectures.
5. What are best practices for API design in microservices architectures?
API design for microservices emphasizes loose coupling, scalability, and resilience. Best practices include using API gateways, implementing service discovery patterns, and carefully managing dependencies to maintain flexibility and fault tolerance.
6. What is the role of API-first design?
API-first design emphasizes designing APIs before implementation, ensuring consistency, usability, and alignment with business requirements. This approach improves collaboration and accelerates development.
7. How do schema definitions improve API design?
Schema definitions, such as those created with OpenAPI or JSON Schema, provide clear contracts between services. They improve validation, maintainability, and developer experience.
8. What are common mistakes in API design?
Common mistakes include inconsistent naming, poor versioning strategies, lack of documentation, and not considering scalability early. Avoiding these pitfalls improves long-term reliability.
