    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 key configuration item (CI) classes, distinguishing cloud and non-cloud resources based on specific class and relationship criteria. This enables ServiceNow customers to accurately categorize and visualize their infrastructure components as cloud or non-cloud within the CI overview tile.

    Class-specific Criteria and Relationships

    The chart uses tailored criteria for each CI class to determine cloud versus non-cloud classification, relying on relationships to datacenters and cloud service accounts. Key classes and their criteria include:

    • Virtual Machine Instance [cmdbcivminstance]: Cloud instances are hosted on datacenters configured as cloud and linked to cloud service accounts. Non-cloud instances are hosted on non-cloud datacenters.
    • Server [cmdbciserver]: Cloud servers are virtualized by cloud virtual machine instances linked to cloud datacenters and cloud service accounts. Non-cloud servers either relate to non-cloud datacenters or lack VM instance relationships.
    • Application [cmdbciappl]: Cloud applications run on servers virtualized by cloud VM instances or are directly hosted on cloud datacenters with cloud service accounts. Non-cloud applications relate to non-cloud datacenters or lack VM instance relationships.
    • Kubernetes Cluster [cmdbcikubernetescluster]: Cloud clusters are hosted on cloud logical datacenters linked to cloud service accounts. Non-cloud clusters relate to non-cloud datacenters or lack datacenter relationships.
    • Database Instance [cmdbcidbinstance]: Cloud databases run on servers virtualized by cloud VM instances or are directly associated with cloud logical datacenters and cloud service accounts. Non-cloud databases relate to non-cloud datacenters or lack VM instance relationships.
    • Storage Volume [cmdbcistoragevolume]: Cloud volumes are hosted on cloud logical datacenters linked to cloud service accounts. Non-cloud volumes relate to non-cloud datacenters or lack datacenter relationships.
    • Cloud Object Storage [cmdbcicloudobjectstorage]: Always considered cloud resources, requiring CMDB CI Class Models. Non-cloud classification does not apply.
    • Service Accounts [cmdbcicloudserviceaccount]: Classified as cloud based on the datacentertype attribute; non-cloud classification does not apply.

    Practical Implications for ServiceNow Customers

    This classification approach allows customers to:

    • Clearly differentiate cloud and non-cloud resources across multiple key CI classes.
    • Leverage relationship-based logic to ensure accurate and dynamic resource categorization.
    • Use the Cloud vs Non-cloud resources chart within the CMDB Workspace for insightful infrastructure visualization.
    • Understand total counts per class, considering possible records without relationships that might affect totals.

    By applying these criteria, customers can maintain an up-to-date and precise view of their hybrid infrastructure landscape, aiding in capacity planning, compliance, and cloud migration initiatives.

    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]:
