    Summary of Class-specific criteria for the Cloud vs Non-cloud resources chart

    The Cloud vs Non-cloud resources chart in the CMDB Workspace store app provides counts of various Configuration Item (CI) classes, distinguishing between cloud and non-cloud resources based on specific class and relationship criteria. This chart is displayed in the CI overview tile and helps ServiceNow customers understand the distribution of their infrastructure and applications across cloud and non-cloud environments.

    Class-specific Criteria and Relationships

    The chart categorizes resources into cloud or non-cloud by evaluating their relationships to datacenters and cloud service accounts. Key CI classes included are Virtual Machine Instance, Server, Application, Kubernetes Cluster, Database Instance, Storage Volume, Cloud Object Storage, and Service Accounts. Each class uses tailored criteria to classify resources:

    • Virtual Machine Instance: Classified as cloud if hosted on datacenters identified as cloud and linked to a cloud service account; otherwise non-cloud.
    • Server: Classified as cloud if virtualized by a cloud-classified Virtual Machine Instance connected to cloud datacenters and cloud service accounts; non-cloud if linked to non-cloud datacenters or without virtualization relationships.
    • Application: Cloud classification requires running on servers virtualized by cloud Virtual Machine Instances or directly hosted on cloud datacenters with cloud service accounts; non-cloud if associated with non-cloud datacenters or servers without virtualization.
    • Kubernetes Cluster: Cloud if hosted on cloud datacenters linked to cloud service accounts; non-cloud otherwise or without datacenter relationships.
    • Database Instance: Cloud classification requires running on servers virtualized by cloud Virtual Machine Instances or directly linked to cloud datacenters and cloud service accounts; non-cloud if associated with non-cloud datacenters or lacking virtualization relationships.
    • Storage Volume: Cloud if hosted on cloud logical datacenters linked to cloud service accounts; non-cloud if linked to non-cloud datacenters or missing datacenter relationships.
    • Cloud Object Storage: Always cloud; non-cloud classification does not apply.
    • Service Accounts: Classified as cloud based on a populated datacentertype attribute; non-cloud classification does not apply.

    Counting and Totals

    Totals for each class generally represent the sum of cloud and non-cloud classified resources, with some exceptions where records lacking relationships may be excluded. For example, Application totals reflect the sum of cloud and non-cloud applications rather than the total number of application records. This ensures accurate reflection of resources correctly associated with cloud or non-cloud environments.

    Practical Implications for ServiceNow Customers

    Understanding these classification criteria enables customers to accurately assess their infrastructure distribution and compliance in the CMDB, aiding cloud migration planning, cost management, and operational visibility. Proper configuration of datacenter classes and cloud service accounts is essential to ensure correct classification and reporting in the Cloud vs Non-cloud resources chart.

    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:
