Serverless Architecture in AWS and Serverless Application Model(SAM)

1. Overview

Serverless is a new paradigm in which the developers don't have to manage servers anymore. They just deploy code and functions such as Function as a Service(Faas). Serverless was pioneered by AWS Lambda but now also includes anything that's managed: "databases, messaging, storage, and etc."

Serverless does not mean there are no servers. It means you just don't manage/provision/see them.

• AWS Lambda
• DynamoDB
• AWS Cognito
• AWS API Gateway
• S3
• AWS SNS & SQS
• AWS Kinesis Data Firehouse

• All the configuration is YAML code
  • Lambda Function
  • DynamoDB tables
