For many releases, Esri has provided pre-built Amazon Machine Images (AMIs) for customers running ArcGIS Enterprise on Amazon Web Services (AWS). ArcGIS Enterprise 10.9.1 will be the last release for which pre-built AMIs will be available in the AWS Marketplace.
Note: This deprecation only affects AMIs in the AWS Marketplace and does not impact the continued availability of similar machine images in the Microsoft Azure Marketplace.
Customers that make use of the pre-built AMIs listed in the AWS Marketplace have a number of alternatives. Beginning with ArcGIS Enterprise 10.9.1, a new Image Builder CloudFormation template will be available to generate an AMI using your own AWS account. It is also possible to manually create an AMI by installing the individual ArcGIS Enterprise software components on a compatible base AMI of your choice.
