    Summary of Avi Load Balancer Extension Classes

    The Avi Load Balancer extension classes enhance the Configuration Management Database (CMDB) by adding or updating classes specifically for the Avi load balancer. These classes integrate into the CMDB class hierarchy, allowing applications like Discovery and Service Mapping to effectively populate and manage Configuration Items (CIs) across various technologies.

    Key Features

    • Class Models: The extension includes classes such as Avi Controller, Avi Controller Cluster, and Avi Service Engine, each serving specific roles within the Avi Vantage system.
    • Separation of Data and Control Planes: The Avi Vantage platform architecture delivers flexibility, allowing for advanced application services beyond simple load balancing.
    • Dynamic Resource Management: Supports a centrally managed pool of load balancing resources across on-premises and cloud environments.
    • Discovery Integration: Uses a dedicated discovery pattern to locate Avi load balancer resources, enhancing visibility and management.

    Key Outcomes

    By leveraging these extension classes, ServiceNow customers can expect improved management of load balancing resources, efficient data analysis via the Avi Admin Console, and streamlined operations that scale effectively without the complexity of managing multiple appliances. The added functionality facilitates better insights and control over application services, ultimately enhancing service delivery in IT environments.

    The CMDB CI Class Models store app adds or updates classes for the Avi load balancer.

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

    Avi load balancer

    The Avi Vantage platform is built on software-defined principles, enabling a next generation architecture to deliver the flexibility and simplicity expected by IT and lines of business. The Avi Vantage platform architecture separates the data and control planes to deliver application services beyond load balancing, such as application analytics, predictive autoscaling, micro-segmentation, and self-service, for app owners in on-premises or cloud environments. The platform provides a centrally managed, dynamic pool of load balancing resources on commodity x86 servers, virtual machines, or containers, to deliver granular services close to individual applications. Providing these services allows network services to scale near infinitely without the added complexity of managing hundreds of disparate appliances.

    Discovery uses the Avi Vantage load balancer discovery pattern to find Avi load balancer resources.

    Classes

    This section lists the classes that the CMDB CI Class Models store app adds or updates. CMDB CI Class Models: Release 1.6.0 adds the following classes for the Avi load balancer. For the list of classes in a base system, including classes that this store app might be extending, see CMDB tables descriptions.

    Class Extends Description
    Avi Controller

    [cmdb_ci_avi_controller]

    		 Virtual Machine Object

    [cmdb_ci_vm_object]

    		 Avi Controller is a single point of management and control that is the 'brain' of the entire Avi Vantage system, and typically deployed as a redundant three-node cluster.
    Avi Controller Cluster

    [cmdb_ci_avi_controller_cluster]

    		 Virtual Machine Object

    [cmdb_ci_vm_object]

    		 Avi Controller cluster uses big data analytics to analyze the data and present actionable insights to administrators on intuitive dashboards on the Avi Admin Console.
    Avi Service Engine

    [cmdb_ci_avi_service_engine]

    		 Virtual Machine Object

    [cmdb_ci_vm_object]

    		 Avi Service Engines (SEs) handle all data plane operations within Avi Vantage by receiving and executing instructions from the Avi Controller.

    Class columns

    CMDB CI Class Models: Release 1.6.0 adds the following column to the respective class.
