Run multiple versions of the same API simultaneously with API Gateway, allowing you to quickly iterate, test, and release new versions. You pay only for calls made to your APIs and data transfer out and there are no minimum fees or upfront commitments.

Monitor performance metrics and information on API calls, data latency, and error rates from the API Gateway dashboard, which allows you to visually monitor calls to your services using Amazon CloudWatch.

Provide end users with the lowest possible latency for API requests and responses by taking advantage of our global network of edge locations using Amazon CloudFront. Throttle traffic and cache the output of API calls to ensure that backend operations withstand traffic spikes and backend systems are not unnecessarily called.

API Gateway provides a tiered pricing model for API requests. With an API Requests price as low as $1.51 per million requests at the highest tier, you can decrease your costs based on the number of API requests you make per region across your AWS accounts.

Authorize access to your APIs with AWS Identity and Access Management (IAM) and Amazon Cognito. If you use OAuth tokens or other authorization mechanisms, API Gateway can help you verify incoming requests by executing a Lambda authorizer from AWS Lambda.

Create resource-based APIs and use API Gateway’s data transformation capabilities to generate the requests in the language target services expect. API Gateway also helps protect your existing services by enforcing throttling rules to ensure that your backend can withstand unpredictable spikes in traffic.

Create REST APIs using API Gateway that mobile and web applications can use to call publicly available AWS services through code running in AWS Lambda. Lambda runs your code on a high-availability compute infrastructure, eliminating the need to provision, scale, or manage any servers.
