## Summary of GCP Networking pattern-based discovery

The GCP Networking pattern-based discovery enables ServiceNow customers to automatically identify and map Google Cloud Platform (GCP) networking resources within their cloud environment.
This discovery populates key networking configuration items (CIs) into the Configuration Management Database (CMDB), facilitating improved visibility and management of cloud networking infrastructure.
To leverage this capability, customers should ensure they meet the discovery prerequisites and use the latest version of the Discovery and Service Mapping Patterns application.

## Key Features

* **Discovery of GCP Networking Resources:** Automatically detects and collects detailed data on various GCP networking components including Cloud Service Accounts, Availability Zones, Google Datacenters, Cloud Networks (VPCs), Cloud Subnets, Network ACLs (firewall rules), and Network ACL Rules.
* **Comprehensive Data Collection:** Gathers essential attributes for each CI such as unique identifiers, names, states, descriptions, IP ranges, operational statuses, and routing details. This ensures accurate representation of the GCP networking environment.
* **Relationship Mapping:** Establishes important relationships between CIs, such as which datacenters host availability zones, networks hosting subnets, and ACLs containing specific firewall rules. This relational mapping supports comprehensive service and infrastructure visualization.
* **Support for Operational and Install Status:** Each CI includes install and operational status indicators, allowing customers to track the health and readiness of networking resources.

## Practical Benefits for ServiceNow Customers

* Enables automated, pattern-based discovery of GCP networking assets, reducing manual inventory effort and increasing accuracy.
* Provides a detailed and structured view of GCP networking infrastructure within the CMDB, aiding impact analysis and change management.
* Supports compliance and governance by maintaining up-to-date firewall rules and network configurations.
* Facilitates troubleshooting and operational monitoring by linking networking CIs with their relationships and statuses.

## Usage Considerations

Customers should verify they have met all GCP discovery prerequisites and have installed the latest Discovery and Service Mapping Patterns application from the ServiceNow Store to ensure full compatibility and functionality.  
Discovery and Service Mapping Patterns finds GCP networking resources on your cloud environment. 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-networking-pattern__section_rpj_fj2_bgc}

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.").

## Data collected by Discovery during horizontal discovery {#gcp-networking-pattern__section_ggp_ql2_bgc}

Discovery populates the data in the CMDB when running the Google Cloud Platform (GCP) - Networking pattern.
