Data-driven applications have their application flow governed by the data, and the serverless framework can serve as the web framework to create this kind of application. In this course, join instructor Marcia Villalba as she takes you through an overview of serverless applications and Kinesis. Learn how to design an event-driven application, how to integrate AWS Lambda and Kinesis streams, and how to set up necessary permissions. Also, discover how to leverage CloudFormation, API Gateway, SES, SNS, and SQS, and more.

Use Cases

• Wrapping an existing internal or external endpoint/service

Invoke the function locally

serverless invoke local --function createOrder

Which should result in:

Serverless: Your function ran successfully.

{
    "orderId": "dd2fa180-ee88-11e9-bf06-af6ce8bc5b1b",
    "name": "manoj",
    "address": "google",
    "productId": "delta1",
    "quantity": "12",
    "orderDate": 1571060720536,
    "eventType": "order_placed"
}

Deploy

In order to deploy the endpoint, simply run:

serverless deploy

The expected result should be similar to:
