    Summary of Google Cloud Platform (GCP) Memorystore discovery using patterns

    This pattern enables ServiceNow customers to discover and map Google Cloud Platform (GCP) Memorystore resources, including Memorystore for Memcached and Memorystore for Redis, during horizontal discovery. It uses the Google Cloud Platform (GCP) - Memorystore DB pattern available in the Discovery and Service Mapping Patterns application. To fully utilize this pattern, customers should ensure they have the latest version of the application from the ServiceNow Store and meet the GCP discovery prerequisites.

    Key Features

    • New CI Classes: Introduces the Cloud DataBase Cluster [cmdbciclouddbcluster] class, extending Cluster [cmdbcicluster], to represent Memorystore clusters.
    • Extensive Data Collection: Discovers and populates critical attributes for various CIs including Cloud Service Accounts, Availability Zones, Google Datacenters, Cloud Database Clusters, and Cloud Databases with detailed fields such as cluster status, node count, authentication settings, IP addresses, and operational status.
    • Dependency Views: Visualize discovered Memorystore instances and clusters along with their relationships for better service mapping and impact analysis.
    • CI Relationships and References: Automatically creates and maintains relationships such as hosting, replication, containment, and ownership between Memorystore components and associated GCP infrastructure elements.
    • Tag Discovery: Collects resource tags and stores them in the CMDB’s Key Value table, enabling enhanced filtering, reporting, and management based on tags.

    Key Outcomes

    • Accurate and comprehensive discovery of Memorystore for Memcached and Redis resources within GCP environments, enhancing visibility into cloud databases.
    • Improved CMDB data quality through the collection of detailed attributes and relationships, supporting better configuration management and service mapping.
    • Ability to track resource states, operational statuses, and cluster configurations to support operational and security governance.
    • Enhanced dependency mapping facilitates impact analysis and troubleshooting by clearly showing how Memorystore instances relate to GCP availability zones, datacenters, and service accounts.
    • Tagging integration aids in organizing and managing cloud resources according to customer-specific tagging schemes.

    Discovery and Service Mapping Patterns uses the Google Cloud Platform (GCP) - Memorystore DB pattern to discover Memorystore for Memcached and Memorystore for Redis during horizontal discovery. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.
