Overview:

Amazon API Gateway offers multiple endpoint types to cater to different use cases and network requirements. These endpoint types include:

  • Edge-Optimized Endpoints

  • Regional Endpoints

  • Private Endpoints

1. Edge-Optimized Endpoints

Overview:

Edge-optimized endpoints are designed to deliver APIs globally with low latency.

These endpoints use Amazon CloudFront’s globally distributed edge locations to cache and accelerate requests.

Key Features

  • Suitable for geographically distributed clients.

  • Integrated with CloudFront for caching and performance.

  • SSL/TLS termination at edge locations.

  • Automatic scaling to handle high traffic.

Real-Time Use Cases

  • Public APIs accessed by users from different regions.

  • APIs serving global applications like e-commerce platforms or SaaS solutions.

2. Regional Endpoints

Overview:

Regional endpoints are used when APIs need to serve clients within the same AWS region, offering low latency and reduced cost compared to edge-optimized endpoints.

Key Features

  • Lower latency for in-region API calls.

  • Better control over custom caching and integrations.

  • Cost-effective as CloudFront is optional.

  • Supports direct VPC endpoint integration.

Real-Time Use Cases

  • Internal applications used within a specific AWS region.

  • APIs interacting with in-region microservices.

  • Applications that require high security and compliance with regional data residency laws.

3. Private Endpoints

Overview:

Private endpoints enable API Gateway to be accessed within an Amazon Virtual Private Cloud (VPC) through AWS PrivateLink.

These endpoints ensure that the APIs are not exposed to the internet.

Key Features

  • Secure, private access within VPCs.

  • No public internet exposure.

  • Supports inter-VPC communication via peering or Transit Gateway.

  • Fully integrated with AWS IAM for fine-grained access control.

Real-Time Use Cases

  • APIs for internal business operations within a secure network.

  • APIs accessed by services running in private VPCs.

  • Environments requiring compliance with strict security standards, like financial or healthcare industries.
