AWS Serverless Applications using SAM -Basics
Introduction
In one of previous posts we’ve discussed AWS Cloud Formation Service and how it helps us manage our infrastructure as code and simplify deployment tasks on AWS.
AWS Serverless Application Model (SAM) takes it to the next level by simplifying the deployment of serverless resources.
The AWS Serverless Application Model (SAM) is an open-source framework for building serverless applications. It provides shorthand syntax to express functions, APIs, databases, and event source mappings.
SAM builds upon CloudFormation service and CloudFormation Templates. So, it is not a new service but is an extension of AWS CloudFormation. You can define and deploy serverless SAM and non-SAM resources using SAM.
In this post, we will take first steps and setup a SAM template which will automate the packaging and deployment of a simple lambda function and wire it up with AWS API Gateway, so it can be triggered by an HTTP Request.
What we will be Building
As this is an introductory post, we will keep it simple. The following picture shows the AWS resources, we’ll be defining and deploying using AWS SAM:
