Optimize AWS discovery by limiting it to datacenters with resources.

## Before you begin

Verify that you have installed Discovery and Service Mapping Patterns, starting with version 1.29.0.

Role required: discovery_admin

## About this task

Starting with version 1.29.0, Discovery and Service Mapping Patterns introduces a new AWS datacenter discovery model that focuses discovery on datacenters with resources and excludes datacenters that don't contain resource. To limit discovery to datacenters that contain resources, set
the mid.cloud.discovery.sonar.discover_all_aws_datacenters
MID Server property to false. For more information, see [Amazon AWS Cloud components discovery using patterns](https://servicenow-prod.fluidtopics.net/nnBwzYmMo_kpTZpG3y5~xQ "Discovery and Service Mapping Patterns uses patterns to discover components of the Amazon AWS Cloud deployment during horizontal discovery. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.").

## Procedure

1. Navigate to AllMID ServerProperties.
2. In the Name column, search for the <kbd class="ph userinput">mid.cloud.discovery.sonar.discover_all_aws_datacenters</kbd> property.
3. Select the mid.cloud.discovery.sonar.discover_all_aws_datacenters property.
4. In the Value field, enter <kbd class="ph userinput">false</kbd>.
5. Select Update.
