Apigee 提供 API Proxy 層，位於後端服務與想使用您服務的內部或外部用戶端之間。Apigee 提供豐富的政策，可讓您在 API Proxy 層新增安全性、流量管理、資料中介、擴充功能和其他功能，打造穩固的企業級 API 管理解決方案。您也可以新增自訂程式碼、條件邏輯、錯誤處理、速率限制、快取和許多其他動作。
由於政策和動作是在 Apigee 的 API Proxy 層級實作，因此底層後端服務可以維持不變。
可靠性：API 消費者需要後端服務的可靠性，才能確保自己的用戶端應用程式順暢運作。維持一致的 API 介面，可讓 API 產生者實作後端服務變更，而不會中斷 API 消費者。
使用 Apigee 的主要優點
Apigee API 管理服務提供專為滿足 API 供應商和消費者需求而設計的功能。
API 可探索性
Apigee 提供以開發人員為主的入口網站，方便用戶端應用程式開發人員探索您的 API、尋找使用 API 建構應用程式所需的說明文件，以及註冊為應用程式開發人員，隨時掌握最新資訊或變更。如要進一步瞭解開發人員入口網站，請參閱
發布總覽。
API 洞察資料
Apigee 提供進階 API 安全性、API 監控和
數據分析功能，可協助 API 產生者確保服務存取安全、監控正常運作時間和流量 (並設定快訊)，以及深入瞭解 API 的使用情形。
API 可靠性
Apigee 提供一致的介面，方便您管理及使用 API。您可以在 Proxy 層級執行 API 的安全性、流量管理和效率政策。使用 Apigee Proxy 可將 API 消費者與後端服務隔離。也就是說，您可以在變更後端時，允許用戶端應用程式不中斷地使用服務。詳情請參閱「
建構簡單的 API Proxy」。

Apigee offers high performance API proxies to create a\nconsistent, reliable interface for your backend services. The proxy layer gives you granular control over security,\nrate limiting, quotas, analytics, and more for all of your services.\n\nApigee supports [REST](/apigee/docs/api-platform/fundamentals/understanding-apis-and-api-proxies),\n[gRPC](/apigee/docs/api-platform/reference/policies/external-callout-policy), [SOAP](/apigee/docs/api-platform/reference/policies/message-validation-policy),\nand [GraphQL](/apigee/docs/api-platform/reference/policies/graphql-policy), providing\nthe flexibility to implement any API architectural style.\n\n| **Note:** Want to jump right to the Apigee technical feature overview, including features for both Apigee and Apigee hybrid? See the [Technical feature overview](/apigee/docs/api-platform/get-started/apigee-feature-summary).\n\nWhat does Apigee provide?\n-------------------------\n\nApigee provides an API proxy layer that sits between your backend services and internal or external clients\nthat want to use your services. Apigee provides a rich array of policies that allow you to add security, traffic management,\ndata mediation, extensions, and other features to the API proxy layer for a robust, enterprise-grade API management solution.\nYou can also add custom code, conditional logic, fault handling, rate limiting, caching, and many other actions.\nBecause the policies and actions are implemented on Apigee, in the API proxy layer, your underlying backend services can remain unchanged.\n\nWho uses Apigee?\n----------------\n\nApigee is designed to benefit two key types of users and the unique API management challenges they face:\n\n- **API producers**: API producers build and manage the APIs that expose their backend services.\n- **API consumers**: API consumers use the data provided by the API in their client applications.\n\n### Challenges for API producers\n\nAPI producers face a specific set of challenges when exposing backend services, such as:\n\n- **Security**: Because API producers make their services available over the web, they must take all necessary steps to secure and protect their services from unauthorized access.\n- **Discoverability**: API producers must ensure that client application developers can find their APIs and use them. As services change, the API producer needs to keep app developers aware of updates and ensure that the services remain compatible with other platforms and devices.\n- **Measurability**: As an API producer, you should monitor your services to make sure they are always available to client applications. You may also want to measure traffic, set quotas, and gain insight into who is using your services.\n\n### Challenges for API consumers\n\nClient app developers consuming services from numerous providers face a slightly different set of challenges, such as:\n\n- **Flexibility**: There are many technologies available today for a service provider to expose its services. The same client app might have to use one method to consume a service from one provider, and a different method to consume a service from a different provider.\n- **Ease of use**: API consumers want to use APIs that are well-designed, easily discoverable, and well-documented so they can get started quickly.\n- **Reliability**: API consumers depend upon the reliability of the backend services to keep their own client applications running smoothly. Maintaining a consistent API interface allows API producers to implement backend service changes without disruption to API consumers.\n\nKey benefits of using Apigee\n----------------------------\n\nApigee API management offers features designed specifically to meet the needs of API producers and consumers.\n\n### API discoverability\n\nApigee offers API producers a developer-focused portal where client app developers can discover your APIs,\nfind the documentation required to build applications using them, and register as an app developer to stay\nin sync with any updates or changes. Learn more about developer portals in the [Publishing overview](/apigee/docs/api-platform/publish/publishing-overview).\n\n### API insights\n\nApigee offers [Advanced API security](/apigee/docs/api-security),\n[API monitoring](https://cloud.google.com/apigee/docs/api-monitoring), and [analytics](https://cloud.google.com/apigee/docs/api-platform/analytics/analytics-services-overview) features that enable API producers to secure access to their services, monitor uptime\nand traffic with alerting, and gain insight into how their APIs are being used.\n\n### API reliability\n\nApigee provides a consistent interface for API management and consumption. You can execute policies\nfor security, traffic management, and efficiency of your APIs at the proxy level. Using Apigee proxies\nallows you to isolate API consumers from your backend service. This means that you can make changes\nto your backend while allowing client applications to consume your services without interruption.\nFor more information, see [Building a simple API proxy.](/apigee/docs/api-platform/fundamentals/build-simple-api-proxy)\n\nWhat's Next\n-----------\n\nAre you ready to get started with Apigee?
