    Summary of OpenStack extension classes

    The CMDB CI Class Models store app extends the ServiceNow Configuration Management Database (CMDB) by adding and updating classes specifically for OpenStack environments. These extensions integrate OpenStack components into the CMDB class hierarchy, allowing customers to manage OpenStack resources alongside other configuration items (CIs).

    OpenStack is a cloud operating system that manages compute, storage, and networking resources across datacenters through APIs. It includes modular services for orchestration, fault, and service management to ensure application availability and scalability.

    Key Features

    • New OpenStack Classes: The app introduces three main classes extending the Virtual Machine Object:
      • OpenStack Services [cmdbcicloudopenstackservice]: Represents OpenStack web services accessible via URLs.
      • OpenStack Endpoint [cmdbcicloudopenstackendpoint]: Represents access points for services.
      • OpenStack Domain [cmdbcicloudopenstackdomain]: Represents collections of users, groups, and projects.
    • Class Extensions: Each class includes additional columns relevant to OpenStack management:
      • OpenStack Services: Includes service type (e.g., compute, identity) and enabled status indicating visibility in the service catalog.
      • OpenStack Endpoint: Includes interface type (public, internal, admin) describing endpoint visibility and an enabled flag.
      • OpenStack Domain: Includes an enabled flag to indicate if the domain is active.
    • Integration with Discovery and Service Mapping: These class models allow ServiceNow applications like Discovery and Service Mapping Patterns to discover and populate OpenStack CIs effectively.

    Practical Benefits for ServiceNow Customers

    • Enables comprehensive visibility and management of OpenStack resources within the ServiceNow CMDB.
    • Supports automated discovery and mapping of OpenStack services and endpoints for accurate service models.
    • Facilitates governance and operational control of OpenStack domains, services, and endpoints directly from the CMDB.
    • Allows customers to leverage existing CMDB and ServiceNow platform capabilities for OpenStack cloud infrastructure management.

    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 ensure 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
    Added columns Description
    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).
