API Gateway vs Apigee API vs Cloud Endpoints

Google Cloud offers three API management solutions: API Gateway, Apigee API, and Cloud Endpoints. Each serves different use cases and organizational needs. Understanding the differences helps you choose the right tool for your API management requirements.

1. Cloud Endpoints

Cloud Endpoints is a lightweight API management solution for APIs deployed on Google Cloud. It provides basic API management features like authentication, monitoring, and logging with minimal configuration.

Best for: Simple APIs running on Cloud Run, GKE, or App Engine with basic management needs.

2. API Gateway

API Gateway is a fully managed gateway for serverless backends like Cloud Functions and Cloud Run. It handles authentication, rate limiting, and routing without managing infrastructure.

Best for: Serverless API backends needing a lightweight, scalable gateway.

3. Apigee API

Apigee is an enterprise-grade full-lifecycle API management platform supporting complex policies, developer portals, monetization, and analytics. It is the most feature-rich option.

Best for: Large enterprises needing advanced API governance, monetization, and developer ecosystems.

The below example shows an OpenAPI specification used to define an API for Cloud Endpoints or API Gateway.

It gives the following output when called with ?name=Venkata&key=API_KEY,

{
  "message": "Hello, Venkata! Welcome to GCP API."
}

Comparison Summary:

Cloud Endpoints - Simple, low cost, best for GCP-native backends, supports gRPC and REST.

API Gateway - Serverless-first, managed, best for Cloud Functions and Cloud Run backends.

Apigee - Enterprise-grade, multi-cloud, best for complex API programs with monetization and developer portals.
