Getting Started with AWS API Gateway

AWS API Gateway is a fully managed service that allows developers to create, deploy, and manage APIs at any scale. With features like caching, throttling, and custom domain support, it enables seamless integration with other AWS services and a robust solution for building and securing APIs in the cloud.

In this Cloud Lab, you’ll explore the powerful capabilities of AWS API Gateway. You’ll start by creating an IAM role to provide the necessary permissions for your Lambda function. Next, you’ll design and deploy a Lambda function that will serve as the backend for your HTTP API. Then, you’ll create a REST API using API Gateway with mock integration, enabling it to return the user’s IP address when invoked. Lastly, you’ll enhance your API architecture by constructing an HTTP API and seamlessly integrating it with the Lambda function.

By the end of this Cloud Lab, you’ll have an understanding of API Gateway’s features, including request/response mappings and integration types, and gain practical experience in creating, configuring, and managing APIs using AWS API Gateway.

The following is the high-level architecture diagram of the infrastructure you’ll create in this Cloud Lab:
