    Summary of OpenStack extension classes

    The CMDB CI Class Models store app for ServiceNow extends the Configuration Management Database (CMDB) class hierarchy by adding or updating classes specific to OpenStack. These extensions enable the integration and management of OpenStack resources within your CMDB, allowing you to leverage ServiceNow applications such as Discovery and Service Mapping Patterns to populate configuration items (CIs) and discover OpenStack technologies and software.

    OpenStack itself is a cloud operating system that manages compute, storage, and networking resources across a datacenter through APIs with unified authentication. It is composed of modular services designed for horizontal scalability, allowing easy growth of cloud infrastructure by adding components as needed.

    Key Features

    • New OpenStack Classes Added:
      • OpenStack Services [cmdbcicloudopenstackservice]: Represents OpenStack web services accessible via URLs.
      • OpenStack Endpoint [cmdbcicloudopenstackendpoint]: Represents access points for OpenStack services.
      • OpenStack Domain [cmdbcicloudopenstackdomain]: Represents collections of users, groups, and projects within OpenStack.
    • Class Extensions: These classes extend from the Virtual Machine Object [cmdbcivmobject] base class, integrating OpenStack-specific concepts into the existing CMDB hierarchy.
    • Additional Class Columns:
      • OpenStack Services: Columns for service type (e.g., Compute, identity, network) and enabled status (whether service/endpoints appear in the Service catalog).
      • OpenStack Endpoint: Columns for interface type (public, internal, admin) describing endpoint visibility and enabled status.
      • OpenStack Domain: Column indicating if the domain is enabled.

    Practical Benefits for ServiceNow Customers

    • Integrate OpenStack infrastructure details into your CMDB with standardized class models.
    • Utilize Discovery and Service Mapping to automatically populate and update OpenStack CIs, improving accuracy and visibility.
    • Manage OpenStack services, endpoints, and domains within ServiceNow, including service catalog visibility and access interface types.
    • Leverage these extensions to support cloud management, fault management, and orchestration capabilities tied to OpenStack environments.

    The CMDB CI Class Models store app adds or updates classes for OpenStack.

    The CMDB CI Class Models app adds class models that extend the CMDB class hierarchy, including class descriptions, identification rules, identifier entries, and, if applicable, dependent relationships. You can use the added classes just like any other CMDB class. Applications such as Discovery and Service Mapping Patterns can use the class extensions to populate CIs and discover technologies and software.

    OpenStack

    OpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter. All of these resources are managed and provisioned through APIs with common authentication mechanisms. Other components provide services such as orchestration, fault management, and service management to promote high availability of user applications. OpenStack is broken up into services to enable you to plug and play components depending on your needs. These components are designed for horizontal scalability, so you can easily add new resources to grow your cloud over time.

    Classes

    This section lists the classes that the CMDB CI Class Models store app adds or updates. See the class columns table for further details about the columns added for each class.

    CMDB CI Class Models: Release 1.8.0 adds the following classes for OpenStack. For the list of classes in the base system, including classes that this app might extend, see CMDB tables descriptions.
    Class Extends Description
    OpenStack Services [cmdb_ci_cloud_openstack_service] Virtual Machine Object [cmdb_ci_vm_object] An OpenStack web service that can be accessed via a URL.
    OpenStack Endpoint [cmdb_ci_cloud_openstack_endpoint] Virtual Machine Object [cmdb_ci_vm_object] The access point of a Service.
    OpenStack Domain [cmdb_ci_cloud_openstack_domain] Virtual Machine Object [cmdb_ci_vm_object] A collection of users, groups, and projects.

    Class columns

    CMDB CI Class Models: Release 1.8.0 adds the following columns to the respective classes.
    Table 1. OpenStack Services [cmdb_ci_cloud_openstack_service] class
    Added columns Description
    type The Service type, which describes the API implemented by the Service. Possible values: Compute, ec2, identity, image, network, or volume.
    enabled Defines if the service and its endpoints appear in the Service catalog (true/false).
    Table 2. OpenStack Endpoint [cmdb_ci_cloud_openstack_endpoint] class

    interface The interface type, which describes the visibility of the endpoint. Possible values:
    • public - Visible by end users on a publicly available network interface.
    • internal - Visible by end users on an unmetered internal network interface.
    • admin - Visible by administrative users on a secure network interface.
    enabled Defines if the Service and its endpoints appear in the Service catalog (true/false).
    Table 3. OpenStack Domain [cmdb_ci_cloud_openstack_domain] class
    Added columns Description
    enabled Defines if the domain is enabled (true/false).
