Apigee (Google)

Apigee is a full lifecycle API management platform that enables API providers to design, secure, deploy, monitor, and scale APIs. Apigee sits in-line with runtime API traffic and enforces a set of out-of-the-box API policies, including key validation, quota management, transformation, authorization, and access control. API providers use the customizable developer portal to enable developers to consume APIs easily and securely, and to measure API performance and usage.
