Launch an Amazon RDS MySQL database engine instance in your default Amazon VPC. In the MySQL instance, you create a database (ExampleDB) with a sample table (Employee) in it. For more information about Amazon RDS, see Amazon RDS.
Create a Lambda function to access the ExampleDB database, create a table (Employee), add a few records, and retrieve the records from the table.
Invoke the Lambda function manually and verify the query results. This is how you verify that your Lambda function was able to access the RDS MySQL instance in the VPC.
This tutorial uses the default Amazon VPC in the us-east-1 region in your account. For more information about Amazon VPC, see How to Get Started with Amazon VPCin the Amazon VPC User Guide.
