Automatically establishing App to Resource relationships based on AWS tags without approval flow?

[SM_628]

Hello,

I'm looking for a way to automatically establish relationships between newly-discovered AWS cloud resources (e.g. EC2 instances, S3 buckets, DBs) and cloud applications (i.e. application services) that are already registered in CMDB.

It appears that the Service Mapping functionality is intended to do this, however, based on what I have read from the documentation this requires fairly heavy manual intervention/approval - especially in a dynamic cloud environment where many resources are getting frequently provisioned/deprovisioned: https://docs.servicenow.com/bundle/utah-it-operations-management/page/product/service-mapping/concep...

Is there a way to automatically discover/create a relationship between a given application service and a resource belonging to that application (without the approval workflow), assuming the resource has a tag for the application it belongs to?

Thank you

Yes, there is a way to automatically discover and create relationships between AWS cloud resources and ServiceNow application services, even if the resources are frequently provisioned and deprovisioned. You can use ServiceNow Discovery, which is a ServiceNow feature that automatically discovers and maps IT resources in your infrastructure, including cloud resources.

To establish relationships between AWS resources and ServiceNow application services, you can use ServiceNow Discovery with the following steps:

1. Enable AWS discovery in ServiceNow: In the ServiceNow instance, navigate to the Discovery application and configure the AWS credentials for the discovery process.

2. Create patterns for AWS resources: In ServiceNow Discovery, you can create patterns for different types of AWS resources, such as EC2 instances, S3 buckets, and databases. These patterns define the attributes and relationships of the resources that are discovered.

3. Define relationship rules: You can define relationship rules in ServiceNow Discovery that establish relationships between the AWS resources and the ServiceNow application services. For example, you can create a rule that maps EC2 instances to the application services they belong to based on a tag that identifies the application.

4. Discover AWS resources: Once you have configured the patterns and relationship rules, you can initiate a discovery scan of the AWS infrastructure. ServiceNow Discovery will automatically discover and map the AWS resources to their corresponding application services in ServiceNow.

With ServiceNow Discovery, you can automate the process of discovering and mapping AWS resources to application services in ServiceNow, and you can avoid the need for manual intervention or approval workflows.

Thanks,
