    Summary of GCP Bigtable pattern-based discovery

    The GCP Bigtable pattern-based discovery enables ServiceNow customers to identify and map Google Cloud Bigtable instances within their cloud environment. This capability requires the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store and adherence to GCP discovery prerequisites. The discovery process collects detailed configuration data and populates the Configuration Management Database (CMDB) with Bigtable-related resources and their relationships.

    Key Features

    • Discovery of Core Resources: The pattern discovers several key resource types including Cloud Service Accounts, Availability Zones, Google Datacenters, Bigtable Instances, Bigtable Clusters, and Bigtable Tables.
    • CMDB Population: Each discovered resource is mapped to specific CMDB tables such as cmdbcicloudserviceaccount, cmdbciavailabilityzone, cmdbcigoogledatacenter, cmdbciclouddatabase, cmdbciclouddbcluster, and cmdbcidatabase. Relevant attributes like names, IDs, locations, operational states, and types are captured to provide a comprehensive view.
    • Relationship Mapping: The discovery automatically establishes relationships between CIs to represent hosting, containment, clustering, and replication. Examples include datacenters hosting service accounts, clusters being part of databases, and databases replicating across datacenters.
    • Tag Collection: Tags assigned to Bigtable instances in GCP are gathered and stored in the Key Value [cmdbkeyvalue] table, linking metadata to the corresponding CMDB records.

    What Customers Can Expect

    • Comprehensive visibility into GCP Bigtable environments within ServiceNow’s CMDB, supporting effective cloud resource management.
    • Accurate operational and install status data for Bigtable instances and clusters, aiding in monitoring and lifecycle management.
    • Clear understanding of geographic deployment through location and availability zone attributes.
    • Improved impact analysis and service mapping thanks to detailed CI relationships reflecting real-world resource dependencies.
    • Enhanced tagging information for governance, cost management, and compliance activities related to Bigtable resources.

    Discovery and Service Mapping Patterns finds GCP Bigtable instances on your cloud environment. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.
