Ensure you access the version of the help that corresponds with the version of ArcGIS or Amazon Machine Image you intend to use. The Other versions menu above allows you to access other versions of this page.
If you use the arcgis-ami-linux.template.json or arcgis-ami-windows.template.json template to create a custom Amazon Machine Image (AMI) from an image available on the Amazon Web Services (AWS) Marketplace that you have not used before, you must read the AWS Customer Service Agreement and accept the terms and pricing described in the documents.
Accept the terms for each AMI you use. If you use different accounts, you must accept the terms for each AMI in each account. Each new release of an AMI is also considered a new AMI.
