Which AWS service or tool should the developer use to define serverless resources in YAML?
CloudFormation serverless intrinsic functions
AWS Elastic Beanstalk
AWS Serverless Application Model (AWS SAM)
AWS Cloud Development Kit (AWS CDK)
Explanations:
While CloudFormation supports intrinsic functions to manage resources, it does not specifically focus on serverless applications. AWS SAM is specifically designed for defining serverless applications in a more streamlined way.
AWS Elastic Beanstalk is a Platform as a Service (PaaS) that manages web applications, but it is not tailored for serverless architectures. It does not integrate directly with API Gateway, Lambda, or DynamoDB in a serverless context.
AWS Serverless Application Model (AWS SAM) is specifically built for defining serverless applications using a simplified syntax in YAML. It allows developers to easily define APIs, Lambda functions, and DynamoDB tables, making it the most appropriate choice for this scenario.
The AWS Cloud Development Kit (AWS CDK) is an infrastructure as code (IaC) tool that allows developers to define cloud resources using programming languages. While it can define serverless resources, it is not specifically designed for serverless applications as AWS SAM is.
