Summary of Schemas of Cloud Provisioning and Governance tables

This documentation details the schemas of key tables used in ServiceNow's Cloud Provisioning and Governance, specifically for the Zurich release version as of July 31, 2025. These tables are designed to be cloud-agnostic, enabling customers to manage data for any cloud provider uniformly. The core tables described include Load Balancer, Network Resource, Storage Volume Resource, and Virtual Server Resource, each capturing essential infrastructure components in cloud environments.

Key Features

Load Balancer Table (cmdbcicloudloadbalancer)
Extends from cmdbcivmobject and cmdbci. It stores identifiers and DNS-related attributes, including:

objectid: Typically the load balancer name.
canonicalhostedzoneid/name: AWS Route 53 hosted zone details.
dnsname/fqdn: Public and fully qualified domain names, including CNAME support.
state: Indicates availability or termination status.

Network Resource Table (cmdbcinetwork)
Extends from cmdbcivcenterobject, cmdbcivmobject, and cmdbci. Captures network configuration and state attributes such as:

objectid: Uniquely identifies the network.
cidr/netmask: Defines IP address ranges and subnet masks.
defaultgateway: Holds the Internet Gateway ID used by default for routing.
isshared/isexternal: Flags indicating network sharing across projects and external/internal classification.
dhcpenabled: Specifies if IP addresses are assigned dynamically or statically.
state and terminatedon: Network availability and de-provisioning timestamps.

Storage Volume Resource Table (cmdbcistoragevolume)
Extends directly from cmdbci. Focuses on storage details:

objectid and volumeid: Unique identifiers for volumes.
volumecontainer: Specific to NetApp storage, differentiating LUN and volume containers.
sharable and sharecount: Indicates if volumes are shared across multiple VMs and the count of such VMs.
storagetype: Cloud-specific storage classifications (e.g., AWS Block, Azure PageBlob).
size, freespace, and state: Capacity details and current usage status.

Virtual Server Resource Table (cmdbcivminstance)
Extends from cmdbcivmobject and cmdbci. Manages VM instance attributes:

objectid and name: Unique VM instance identifier and name.
state: Indicates VM power state such as on, off, or terminated.
cpus, memory, disks, disksize, nics: Hardware resource specifications.
terminationprotection: Boolean flag to prevent accidental termination (default false).
terminatedon: Timestamp of VM termination.

Practical Use for ServiceNow Customers

These schemas provide a standardized data model to manage cloud infrastructure components regardless of the cloud provider. By leveraging these tables, customers can:

Inventory and track cloud resources with consistent identifiers and attributes.
Understand and manage resource states such as availability and termination.
Control resource-specific properties like network sharing, storage sharing, and termination protection.
Map and manage cloud infrastructure relationships through inheritance and extensions in the data model.

This enables a unified and flexible approach to cloud provisioning, governance, and lifecycle management within the ServiceNow platform.

The tables are cloud-agnostic and can therefore hold data for any cloud provider.

Load balancer table

The load balancer table [cmdb_ci_cloud_load_balancer] extends from [cmdb_ci_vm_object], which extends from [cmdb_ci]. Click to enlarge the image.

Load balancer CMDB object model — Figure 1. Schema load balancer

Table 1. Key native attributes of the cmdb_ci_cloud_load_balancer table
Attribute	Description
object_id	Identifier that typically holds the load balancer name as the value.
canonical_hosted_zone_id	ID of the Amazon Route 53 hosted zone for the load balancer.
canonical_hosted_zone_name	DNS name of the load balancer.
dns_name	Public DNS name of the load balancer.
fqdn	DNS name as fully qualified domain name. Can also be a CNAME record pointed to the DNS name.
state	State of the load balancer: available or terminated.

Network resource table

The network resource table [cmdb_ci_network] extends from [cmdb_ci_vcenter_object], which extends from [cmdb_ci_vm_object], which extends from [cmdb_ci]. Click to enlarge the image.

Table 2. Key native attributes of the cmdb_ci_network table
Attribute	Description
object_id	Identifier that typically holds the network ID as the value. Uniquely identifies an object within a cloud.
name	Name of the network.
cidr	IP Address range. Classless inter-domain routing is a set of internet protocol standards that is used to create unique identifiers for networks.
default_gateway	Holds InternetGatewayID if we attach IntenetGateway to the network. A default gateway serves as an access point or IP router that a networked computer uses to send information to a computer in another network or Internet. The specified gateway is used by default unless an application specifies a different gateway.
Broadcast_address	IP address used to transmit messages and data packets to network systems.
Is_shared	Boolean. true: Network shared across other projects. false: Network not shared across other projects.
max_ports	Maximum number of hosts that can be connected to the network
is_external	Boolean. true: Network is external. false: Network is internal.
terminated_on	Time that the network was de-provisioned.
state	State of the network: available or terminated.
netmask	Type of CIDR. 32-bit mask that divides an IP address into subnets and specify the hosts that are available on the network.
dhcp_enabled	Boolean: true: Dynamic IP address is assigned to host false: Static IP address is assigned to host

Storage volume resource table

The storage volume resource table [cmdb_ci_storage_volume] extends from [cmdb_ci]. Click to enlarge the image.

Table 3. Key native attributes of the cmdb_ci_storage_volume table
Attribute	Description
object_id	Identifier that typically holds the object ID as the value. Uniquely identifies an object within a cloud.
volume_id	Identifier that typically holds the volume ID as the value. Uniquely identifies an object within a cloud.
volume_container	For NetApp only, LUN becomes the volume and NetApp volume becomes the volume container.
sharable	Boolean. true: Volume is shared by multiple VMs. false: Volume is not shared by multiple VMs.
storage_type	Type of storage. AWS: Block Azure: PageBlob vSphere: VMware vdisk
size	Total capacity of the volume.
free_space	Available space of the volume
state	State of the volume: available or in_use.
share_count	Number of VMs that are shared by the volume.

Virtual server resource table

The virtual server resource table [cmdb_ci_vm_instance] extends from [cmdb_ci_vm_object], which extends from [cmdb_ci]. Click to enlarge the image.

Table 4. Key native attributes of the cmdb_ci_vm_instance table
Attribute	Description
object_id	Identifier that typically usually holds the VM instance ID. Uniquely identifies an object within a cloud.
name	Name of the VM.
state	State of the VML: on, off, or terminated.
cpus	Number of CPUs.
memory	Memory size in megabytes.
disks	Number of disk drives.
disk_size	Total size of disks in gigabytes.
nics	Number of network interface adapters.
terminated_on	Time that the instance was terminated.
termination_protection	Boolean. Default value is false. true: Can prevent the instance from being accidentally terminated using Amazon EC2. false: Cannot prevent the instance from being accidentally terminated using Amazon EC2.
