Need of AWS Serverless Application Model

The following are the benefits provided by AWS SAM:

• Streamlines the creation, deployment, and administration of serverless applications on Amazon.
• Gives users a common approach to defining serverless resources with a more straightforward syntax.
• Makes it simple to understand and administer by allowing developers to create many serverless resources in a single SAM template.
• Enhances development efficiency by providing built-in facilities for local testing, debugging, and deployment.
• Supports best practices and typical application patterns, ensuring that applications are constructed with security, speed, and scalability in mind.
• Reduces complexity, speeds up development cycles, and helps save time.
• Simplifies the deployment and administration of serverless applications, increasing their effectiveness and practicality.
• Defines the construction and configuration of serverless apps in AWS using an organized methodology.
• Makes sure that serverless application deployment and administration are consistent and repeatable.
• Allows for more accessible and more efficient creation of scalable and dependable serverless applications by developers.

Assume you are developing a complicated web application that calls for numerous API Gateways, Amazon Lambda functions, and serverless resources. These resources require deployment, configuration, scale management, security, and performance optimizations. When using unprocessed CloudFormation templates, this can easily become time-consuming and overwhelming. The AWS Serverless Application Model (SAM), a strong framework that streamlines the process of creating, deploying, and managing serverless apps on AWS, steps in at this point.
 

Let’s imagine, for example, that you are developing a serverless application with several Lambda functions, an API Gateway, and an S3 bucket for file storage. With SAM, all of these resources can be defined in a single SAM template with a simple syntax to comprehend and administer. Each Lambda function’s runtime, memory, and other configurations, the endpoints and authentication for the API Gateway, and the bucket policies for the S3 bucket can all be defined in one location. Thanks to SAM’s integrated features for local testing, debugging, and deployment, your serverless applications may be developed and iterated upon with efficiency and convenience.
