2. Interact with Your Database via Lambda

• Build a new Lambda function
• Test your new Lambda function
• Make your first Put to DynamoDB
• Interact with the results of your DynamoDB Put
• Challenge: Add sample users to the database
• Solution: Add sample users to the database

3. Insert Structured Data into DynamoDB

• Get the request from a web form
• Display a response back from the Lambda
• Update your Lambda to respond based on your Put call
