(Recommended) Deploy an Amazon Elastic Compute Cloud instance to help run automation scripts

We recommend deploying an Amazon Elastic Compute Cloud (Amazon EC2) instance to automate the connection to the solution’s APIs and AWS Boto3 APIs with IAM roles. The following cost estimate assumes that the Amazon EC2 instance is located in the us-east-1 Region and runs eight hours a day, five days a week.

AWS service Factors Cost/month [USD]
Amazon EC2 176 hours a month x $0.1108/per hour (t3.large) $19.50
Amazon Elastic Block Store (Amazon EBS) 30 GB x $0.08/GB-month (gp3) x (176 hours/720 hours) $0.59
