This tutorial assumes AWS familiarity, Java programming experience, and Spring Boot experience. API helps you to plan a business model. This Gateway will redirect to the right Lambda Function based on the … The full source code is available at spring-data-dynamodb-examples’ simple example. If we built our API using HttpApi and Lambda and got 100 million requests per month, the cost for API Gateway would be $100 and the cost for Lambda (assuming 100ms requests and 256MB memory) would be $429.80. So run cdk bootstrap. You will be creating a simple RESTful API that allows you to pull items from DynamoDB.

In this tutorial, you are going to be building a fully-fledged REST API that exposes GET, POST, DELETE and PUT endpoints that will subsequently allow you to perform the full range of CRUD operations. There are tables, which basically are collections of data structures, or in AWS terminology, “items.” Every item has a mandatory “hash,” an optional “range” and a number of other optional attributes. With Pulumi, you can combine infrastructure definitions and application code in one program. You can use the @APIKey mapping to retrieve the API key you entered in the Add a Generic REST API Source panel. Advanced REST Client tool.
