18.6. Introduction to AWS API Gateway: Integrating AWS API Gateway with other AWS services

AWS API Gateway is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale. It allows developers to create RESTful and WebSocket APIs that act as "gateways" for applications to access data, business logic, or functionality from their backend services.

API Gateway allows integration with other AWS services, such as AWS Lambda, Amazon EC2, AWS S3, among others. This integration allows developers to create APIs that utilize the business logic embedded in these services, providing an abstraction layer that simplifies API management and maintenance.

AWS API Gateway integration with AWS Lambda

AWS Lambda is a service that lets you run your code without provisioning or managing servers. With AWS Lambda and API Gateway integration, you can create serverless APIs that run your code in response to events and automatically manage compute resources for you.

To integrate API Gateway with Lambda, you need to create a Lambda function and then create an API in API Gateway. In the API Gateway console, you can configure the Lambda integration to point to the Lambda function. When a client calls your API, API Gateway invokes the Lambda function with the request details and returns the Lambda function response to the client.

AWS API Gateway integration with Amazon EC2

Amazon EC2 is a web service that provides scalable computing capacity in the cloud. It is designed to make web-scale computing easier for developers.

API Gateway's integration with EC2 allows you to create APIs that act as a "gateway" to your EC2 applications. You can configure API Gateway to route requests to a specific EC2 instance or to a load balancer that distributes requests across multiple instances.

To integrate API Gateway with EC2, you need to create an EC2 instance and then create an API in API Gateway. In the API Gateway console, you can configure the EC2 integration to point to the EC2 instance. When a client calls your API, API Gateway forwards the request to the EC2 instance and returns the response from the EC2 instance to the client.

AWS API Gateway integration with AWS S3

Amazon S3 is an object storage service that offers scalability, data availability, security, and performance. With API Gateway and S3 integration, you can create APIs that provide access to objects stored in an S3 bucket.

To integrate API Gateway with S3, you need to create an S3 bucket and then create an API in API Gateway. In the API Gateway console, you can configure the S3 integration to point to your S3 bucket. When a client calls your API, API Gateway forwards the request to the S3 bucket and returns the response from the S3 bucket to the client.

Conclusion

In summary, AWS API Gateway is a powerful tool that allows developers to create robust and scalable APIs with ease. Its ability to integrate with other AWS services makes it possible to create APIs that leverage the business logic built into those services, simplifying API management and maintenance. Whether you're a Python developer working with Lambda, an infrastructure engineer managing EC2 instances, or As a solutions architect designing S3 storage systems, API Gateway has the potential to improve and simplify your workflow.
