Resource Planning diagram here illustrates how the Project Manager will conduct the entire project with the help of the Apigee Architect. It should be noted here that Apigee is a platform for developing and managing APIs. Apigee provides an abstraction or facade for your backend service APIs by fronting services with a proxy layer and provides security, rate limiting, quotas, analytics, and more. In simpler words, Apigee is the cross-cloud API management platform that accelerates the pace of digital business. It gives businesses control over and visibility into the APIs that connect applications and data across the enterprise and clouds. In other words, API proxies decouple the app-facing API from your backend services, shielding those apps from backend code changes. As you make backend changes to your services, apps continue to call the same API without interruption.
