I believe those cloudwatch alarms are specifically for the DynamoDB tables we made during that tutorial series. Since I made them provisioned instead of on-demand, cloudwatch alarms are created so that those tables can scale up or down read and write capacity units in the cases of rising or falling read and write traffic. For small-scale testing purposes, they probably aren't needed so the alarms can be deleted. Note that if you have a lot of variable traffic in a production setting, those alarms will probably be needed for provisioned capacity DyanmoDB tables.

Thanks. I was thinking of deleting them to see if the cost's disappeared. Thanks for the confirmation.
