AWS SAM, or the AWS Serverless Application Model, is an open-source framework for building serverless applications on the Amazon Web Services (AWS) platform. It provides a simplified way to define the resources needed for a serverless application, as well as the relationships between those resources, in an easy-to-understand template format.
There are several benefits to using AWS SAM when building serverless applications on AWS:
- Simplified resource definition: AWS SAM provides a concise syntax for defining the resources needed for a serverless application. This includes things like AWS Lambda functions, Amazon API Gateway APIs, and Amazon DynamoDB tables. By using AWS SAM, you can define all of these resources in a single template file, rather than having to create them individually in the AWS Management Console.
- Better organization: AWS SAM templates allow you to group related resources together, making it easier to understand the overall structure of your serverless application. You can also use AWS SAM to define logical relationships between resources, such as an API Gateway API that invokes a Lambda function, or a DynamoDB table that triggers a Lambda function when an item is added or updated.
- Improved testing: AWS SAM provides a set of command-line tools that make it easy to test your serverless application locally, before deploying it to the cloud. You can use these tools to invoke Lambda functions, test API Gateway APIs, and more, all from the command line.
- Enhanced deployment options: AWS SAM makes it easy to deploy your serverless application to the cloud using the AWS CLI or AWS CloudFormation. You can also use AWS SAM to create and manage different versions of your application, and to quickly roll back to a previous version if needed.
Overall, AWS SAM provides a convenient and powerful way to build and manage serverless applications on the AWS platform. Whether you’re new to serverless development or an experienced pro, AWS SAM can help you build and deploy high-quality serverless applications faster and more easily.5 Benefits of Using AWS SAM for Serverless Application Development
