A company provides devices to users. When a device is registered, its ID is added to DynamoDB. A daily job activates devices using two Lambda functions:

* The Retrieve function then calls the Activate function in a loop to register each device.
The number of activations is increasing, and the company wants to avoid Lambda timeouts without modifying existing functions.
Which solution will scale appropriately?
