    Summary of Class criteria in Cloud vs Non-cloud resources chart

    The Cloud vs Non-cloud resources chart in ServiceNow's CMDB Workspace app provides counts of key configuration item (CI) classes, distinguishing between cloud and non-cloud resources based on specific class and relationship criteria. This chart appears in the CI overview tile and helps customers understand the distribution of their infrastructure across cloud and non-cloud environments.

    Class Criteria and Relationships

    The classification depends on relationships among CIs such as Virtual Machine Instances, Servers, Applications, Kubernetes Clusters, Database Instances, Storage Volumes, Cloud Object Storage, and Service Accounts. Each class uses defined relationship paths to determine if a CI is cloud or non-cloud:

    • Virtual Machine Instance: Cloud instances are linked through hosting and datacenter classes to configured cloud datacenters and cloud service accounts; non-cloud instances link to non-cloud datacenters.
    • Server: Cloud servers are virtualized by VM instances hosted in cloud datacenters with cloud service accounts; non-cloud servers either link to non-cloud datacenters or lack VM instance relationships.
    • Application: Cloud applications run on servers virtualized by cloud VM instances or are hosted directly in cloud datacenters with cloud service accounts; non-cloud applications link to non-cloud datacenters or lack VM instance relationships.
    • Kubernetes Cluster: Classified cloud if hosted in cloud logical datacenters with cloud service accounts; non-cloud if linked to non-cloud datacenters or lacking datacenter relationships.
    • Database Instance: Cloud if running on servers virtualized by cloud VM instances or linked directly to cloud datacenters with cloud service accounts; non-cloud if linked to non-cloud datacenters or missing VM instance relationships.
    • Storage Volume: Cloud volumes are hosted in cloud logical datacenters with cloud service accounts; non-cloud volumes link to non-cloud datacenters or lack datacenter relationships.
    • Cloud Object Storage: Always classified as cloud, requiring CMDB CI Class Models; no non-cloud classification.
    • Service Accounts: Classified as cloud based on the populated datacentertype attribute; no non-cloud classification.

    Key Outcomes

    • Enables accurate inventory and classification of cloud versus non-cloud resources across multiple CI classes.
    • Supports better visibility into infrastructure composition by leveraging CI relationships and datacenter configuration.
    • Helps identify resources lacking proper relationships or misconfigurations through total counts compared to relationship-based classification.
    • Facilitates cloud resource management by associating CIs with cloud service accounts and configured cloud datacenters.

    The Cloud vs Non-cloud resources chart provides counts for several key classes. The chart uses different classes and relationship criteria for each class to determine which resources count as cloud and which count as non-cloud.

    The Cloud vs Non-cloud resources chart shows in the CI overview tile in the CMDB Workspace store app.
    Virtual Machine Instance [cmdb_ci_vm_instance]:
    • Cloud:

      Virtual Machine Instance [cmdb_ci_vm_instance] -> (Hosted on::Hosts) -> Datacenter class (one of the configured cloud datacenters) -> (Hosted on::Hosts) -> Cloud Service Account [cmdb_ci_cloud_service-account]

    • Non-Cloud:

      Virtual Machine Instance [cmdb_ci_vm_instance] -> (Hosted on::Hosts) -> Datacenter class (one of the configured non-cloud datacenters)
