Mirroring deployments overview

A mirroring deployment is a zonal deployment of a producer's third-party appliances. Mirroring deployment acts as a backend to an internal passthrough Network Load Balancer, providing network services on the traffic mirrored from the consumer networks.

The mirroring deployments are grouped in mirroring deployment groups across different locations within a project for easier consumption and management.

This document provides a detailed overview of mirroring deployments and their capabilities.

Specifications

• A mirroring deployment is a project-level resource created at the zonal-level.

• You can deploy only one mirroring deployment per zone and group.

• Each mirroring deployment is associated with a mirroring deployment group. You can associate a mirroring deployment with exactly one deployment group.

• A mirroring deployment references the forwarding rule that points to the backend services where the third-party appliances are deployed to provide mirroring services. This forwarding rule handles the traffic sent to the mirroring deployment. The forwarding rule must use the network specified in the mirroring deployment group.

• Each mirroring deployment is uniquely identified by a URL with the following elements:

  • Project ID: ID of the project.
  • Location: scope of the mirroring deployment. Location is always set to the zone it resides in.
  • Name: mirroring deployment name in the following format:
    • A string 1-63 characters long
    • Includes only lowercase alphanumeric characters or hyphens (-)
    • Must start with a letter

  To construct a unique URL identifier for a mirroring deployment, use the following format:

   projects/ PROJECT_ID 
  /locations/ ZONE 
  /mirroringDeployments/ DEPLOYMENT 
   
  

  Replace the following:

  • PROJECT_ID : ID of the project

  • ZONE : zone of the mirroring deployment

  • DEPLOYMENT : name of the mirroring deployment

  For example, project 2345678432 in zone us-east1-a with mirroring deployment example-mirroring-deployments has the following unique identifier:

   projects/2345678432/locations/us-east1-a/mirroringDeployments/example-mirroring-deployments 
  

Identity and Access Management roles

Identity and Access Management (IAM) roles govern the following actions for managing the mirroring deployments:

• Creating a mirroring deployment in a project
• Modifying or deleting a mirroring deployment
• Viewing details about a mirroring deployment
• Viewing all the mirroring deployments configured in your project

The following table describes the roles that are necessary for each step.
