LABUse Lambda Functions within a Stateless Architecture on AWS
In this lab, you’ll practice using Lambda Functions within a stateless architecture, When you’re finished with this lab, you’ll have learned to run code without provisioning or managing servers.
Terms and conditions apply.
Challenge
Create a Lambda Function with a Role
You’ll configure a Lambda Function with a role, which will have permissions for an S3 bucket and a DynamoDB.
Challenge
Add an S3 Trigger to the Lambda Function
You’ll add an S3 trigger and configure two events, one that triggers when any object is created, the second that triggers when an object is permanently deleted.
Challenge
Add Code to the Lambda Function
You’ll add Python 3.8 code that is triggered by the S3 Bucket events you just created. This code will add an entry to the DynamoDB database table (which was added for you).
Challenge
Trigger Lambda Function Code
When you upload or delete a file in an S3 Bucket, an event will be generated, which will execute the Lambda Function. Its code will add information to the DynamoDB database table.
Challenge
Use AWS Lambda to Trigger Email Notification on S3 Events
When a user uploads or deletes a file in an S3 bucket, an event will be generated, which will trigger the Lambda function and then it will send an email notification and also generate CloudWatch logs.
