Azure API Management logo

Azure API Management

Azure API Management is a platform-as-a-service offering that enables organizations to publish, secure, transform, maintain, and monitor APIs in a hybrid or multicloud environment. It provides a developer portal, analytics, and policy engine for consistent API governance, allowing teams to expose services to internal and external developers with access control, rate limiting, and analytics to ensure secure and scalable API consumption.Read more
