A new version of ArcGIS Server Cloud Builder on Amazon Web Services is released when a new version of ArcGIS Server is released. The most recent version of Cloud Builder creates new ArcGIS Server sites with the most recent ArcGIS update applied and using EC2-VPC instances, unless you are creating a site from a template.
Note:
ArcGIS 10.6.1 is the final release of ArcGIS Server Cloud Builder on Amazon Web Services. After 10.6.1, use ArcGIS Enterprise Cloud Builder Command Line Interface for Amazon Web Services to deploy ArcGIS Server sites instead. Existing sites created with ArcGIS Server Cloud Builder on Amazon Web Services will still function, but once you upgrade the software on the site, you can no longer use Cloud Builder to manage them.
When you create a site from a template, the version of software used in the template and instance type are applied to the new site.
You can download the latest version of Cloud Builder from My Esri. You can access the download if you have purchased ArcGIS Enterprise.
Update notices and restrictions
If Cloud Builder detects that you are not running its latest version, you'll see a message that an upgrade is available. Get the update only after you have determined that you are finished creating new sites at your current ArcGIS version. Once you have accessed your Amazon account using a particular version of Cloud Builder, you cannot go back and access your account using an older version of Cloud Builder.
When you update Cloud Builder, the version numbers of your existing ArcGIS Server sites and templates are not affected. You can still manage your existing sites and templates in the updated Cloud Builder. It's possible to see sites and templates of differing versions listed side by side in Cloud Builder.
