Apigee is a platform for developing and managing APIs. By fronting services with a proxy layer, Apigee provides an abstraction or facade for your backend service APIs and provides security, rate limiting, quotas, analytics, and more.
Apigee consists of the following primary components:
In addition, Apigee uses other components including:
An API proxy is the HTTP endpoint on Apigee that developers use to access your backend services. While it is possible, you typically do not make individual API proxies available. Instead, you group one or more API proxies into an API product.
An API product is a bundle of API proxies combined with a service plan. That service plan can set access limits on API proxies, provide security, allow monitoring and analytics, and provide additional features. API products are also the central mechanism that Apigee uses for authorization and access control to your APIs.
You have a great deal of flexibility when creating API products. For example, multiple API products can share the same API proxy. The following figure shows three API products. Notice that all products allow access to API proxy 3, but only product A allows access to API proxy 1.
You can set different properties on each API product. For example, you might make available one API product with a low access limit, such as 1000 requests per day, for a bargain price. You then release another API product that provides access to the same API proxy, but with a much higher access limit, for a higher price. Or, you might create a free API product that allows read-only access to your services, and then sell an API product to the same API proxies that allows read/write access.
