A service that helps organizations publish, secure, and monitor APIs in a centralized platform.
API Management allows you to control who can access your APIs and monitor usage patterns.
All provide a managed API gateway layer for publishing APIs with authentication/authorization, throttling/quotas, monitoring/analytics, and developer onboarding. Azure API Management and Apigee are full lifecycle API management platforms (developer portal, policies, products). Amazon API Gateway and Oracle API Gateway focus more on gateway capabilities and integrate with broader cloud services for analytics and portals.
