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

The Google Cloud Platform (GCP) - Memorystore DB pattern is used within ServiceNow's Discovery and Service Mapping Patterns application to identify and map Memorystore for Memcached and Memorystore for Redis instances during horizontal discovery.
This pattern requires the latest version of the Discovery and Service Mapping Patterns application and adherence to GCP discovery prerequisites.

## Key Features

* **New CI Class:** The pattern introduces a new CI class `Cloud DataBase Cluster [cmdbciclouddbcluster]` which extends the existing Cluster CI class to represent Memorystore clusters.
* **Data Captured:** Discovery populates detailed CMDB records for various related resources including Cloud Service Accounts, Availability Zones, Google Datacenters, Cloud Database Clusters, and individual Cloud Databases with attributes such as names, IDs, statuses, cluster types, node counts, authentication settings, IP addresses, and more.
* **CI Relationships:** The pattern establishes meaningful relationships between discovered CIs such as hosting relationships between databases and datacenters, replication links between databases, and containment relationships between datacenters and availability zones. These relationships support accurate dependency mapping.
* **Tag Collection:** Tags associated with Memorystore instances are collected and stored in the Key Value table, enabling enhanced filtering and identification within the CMDB.
* **Visualization:** Discovered Memorystore instances and clusters can be visualized in Dependency Views maps, showing connection and dependency details within the customer's GCP environment.

## Key Outcomes

* ServiceNow customers gain comprehensive visibility into their GCP Memorystore environments, including both Memcached and Redis deployments.
* The enriched CMDB data supports improved service mapping, impact analysis, and operational management of cloud database resources.
* Accurate discovery and relationship mapping reduce manual effort and improve confidence in the CMDB's representation of cloud database infrastructure.
* Tagging data enables better organization and governance of cloud resources within ServiceNow.  
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 might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

## Pattern-based discovery and mapping requirements {#gcp-memorystore-patterns__section_kks_j5d_wfc}

Verify the GCP discovery prerequisites section in [Google Cloud Platform (GCP) Cloud discovery using Patterns](https://www.servicenow.com/docs/hH4wPjzyLr0pmFmj6Ib5TA "Discovery and Service Mapping Patterns uses patterns to discover components of the Google Cloud Platform (GCP) deployment during horizontal discovery. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.").

## GCP Memorystore data model {#gcp-memorystore-patterns__section_data_model}

The Google Cloud Platform (GCP) - Memorystore DB pattern introduces the following CI class that extends an existing CMDB class.
