Using the update set for the Amazon AWS Lambda pattern
To use the Amazon AWS Lambda pattern from ServiceNow Store for top-down discovery, import the update set attached to this KB article.
This update set contains a script that finds the correct logical datacenter based on the ARN (Amazon Resource Name) that you enter in the entry point.
For more information on testing and importing update sets, see Update set transfers.
This Pattern depends on some CMDB tables that are not present in the Discovery and/or Service Mapping plugin. e.g. cmdb_ci_cloud_gateway, cmdb_ci_cloud_function.
To use this update set you must first request and then install the current "Discovery and Service Mapping Patterns" application from the Servicenow Store, which will add those tables.
