Before we can invoke our Lambda, we need to create an input and an output queue. We will also send messages to the input queue. When we invoke the Lambda, it will retrieve these messages.

Perform the following steps:

1. Create two SQS queues: an input queue, my-input-queue, and an output queue, my-output-queue, following the Your first Simple Queue Service (SQS) recipe.
2. Send six to seven messages to the queue from CLI.
