To build serverless applications, developers and project managers must know how to transition to an API-driven development environment. Use this course to learn how to leverage APIs within AWS's serverless platform. Distinguish between REST and SOAP APIs. Examine the purpose of the REST architecture style and the benefits of using REST APIs. Explore AWS API Gateway and the process of designing, building, and optimizing API Gateway to create REST APIs. Create HTTP APIs and API Gateway APIs. Implement AWS Lambda using Node.js. Then create Lambda functions to consume events from Amazon DynamoDB streams. Outline how to set up authentication and authorization in AWS serverless implementations. Work with Lambda authorizers and functions. Lastly, customize content delivered by CloudFront. Upon completing this course, you'll be able to build RESTful APIs and leverage them within the AWS serverless environment.
