# AWS hardware type pattern-based discovery

Discovery and Service Mapping Patterns finds Amazon EC2 instance types on your cloud environment. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

Discovery uses the Amazon AWS - Hardware Type \(LP\) pattern to discover AWS EC2 instance types from your AWS account.

When using the Hardware Type \[cmdb\_ci\_compute\_template\] table to store the hardware types, you may notice an unusually large number of records. To avoid this issue, you can store the discovered hardware types in the Cloud Hardware Type \[cmdb\_ci\_cloud\_hardware\_type\] table. When enabled, Discovery launches the Amazon AWS - Cloud Hardware Type \(LP\) pattern to populate the Cloud Hardware Type \[cmdb\_ci\_cloud\_hardware\_type\] table. For more information, see [Enable the Cloud Hardware Type class extension](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-operations-management/discovery-and-service-mapping-patterns/enable-hardware-type-class-extension.md).

## Pattern-based discovery and mapping requirements

Verify the AWS discovery prerequisites section in [AWS discovery using patterns](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-operations-management/discovery-and-service-mapping-patterns/data-discovered-aws-patterns.md).

## Data collected by Discovery during horizontal discovery

Discovery populates the data in the CMDB when running the AWS hardware type patterns.

<table id="table_hardware_type_fields"><thead><tr><th>

Name \[name\]

</td><td>

Name of the instance type.For example: t2.micro or m5.large

</td></tr><tr><td>

Object ID \[object\_id\]

</table>## CI relationships

The AWS hardware type patterns create these relationships to support AWS hardware type discovery.

|CI|Relationship|CI|
|---|------------|---|
|Hardware Type \[cmdb\_ci\_compute\_template\] or Cloud Hardware Type \[cmdb\_ci\_cloud\_hardware\_type\]|Hosted on::Hosts|AWS Datacenter \[cmdb\_ci\_aws\_datacenter\]|
