M4CE(v5) - Host and Target Projects with Shared VPC

This blueprint creates a Migrate for Compute Engine (v5) environment deployed on an host project with multiple target projects and shared VPCs.

The blueprint is designed to implement a M4CE (v5) environment on-top of complex migration landing environment where VMs have to be migrated to multiple target projects. In this blueprint targets are also service projects for a shared VPC. It also includes the IAM wiring needed to make such scenarios work.

This is the high level diagram:

Managed resources and services

This sample creates\update several distinct groups of resources:

• projects
  • M4CE host project with required services deployed on a new or existing project.
  • M4CE target project prerequisites deployed on existing projects.
• IAM
  • Create a service account used at runtime by the M4CE connector for data replication
  • Grant migration admin roles to provided user or group.
  • Grant migration viewer role to provided user or group.
  • Grant roles on shared VPC to migration user or group

Variables

name	description	type	required	default
migration_admin	User or group who can create a new M4CE sources and perform all other migration operations, in IAM format (group:[email protected]).	string	✓
migration_target_projects	List of target projects for m4ce workload migrations.	list(string)	✓
sharedvpc_host_projects	List of host projects that share a VPC with the selected target projects.	list(string)	✓
migration_viewer	User or group authorized to retrieve information about M4CE in the Google Cloud Console, in IAM format (group:[email protected]).	string		null
project_create	Parameters for the creation of the new project to host the M4CE backend.	object({…})		null
project_name	Name of an existing project or of the new project assigned as M4CE host project.	string		"m4ce-host-project-000"

Outputs

name	description	sensitive
m4ce_gmanaged_service_account	Google managed service account created automatically during the migrate connector registration. It is used by M4CE to perform activities on target projects.

Manual Steps

Once this blueprint is deployed the M4CE m4ce_gmanaged_service_account has to be configured to grant the access to the shared VPC and allow the deploy of Compute Engine instances as the result of the migration.
