Managed Service for Microsoft Active Directory (Managed Microsoft AD) offers high-availability, hardened Microsoft Active Directory domains hosted by Google Cloud. This service helps reduce the sensitive but mundane administrative tasks required to manage Active Directory, while also extending your Active Directory footprint into the cloud.
Managed Microsoft AD allows connecting to your existing, on-premises Active Directory infrastructure from Google Cloud through a forest-level trust, facilitating secure access to your organization's data.
How Managed Microsoft AD works
Managed Microsoft AD runs actual Microsoft Active Directory domain controllers on Windows virtual machines to ensure application compatibility. The service creates and maintains the domain controllers for you, reducing the maintenance tasks you need to manage.
Managed Microsoft AD supports multi-regional deployment of Active Directory forests when peered with Google Cloud's global low-latency Virtual Private Cloud (VPC). Within VPC, you can extend Managed Microsoft AD to multiple regions, without requiring VPC peering or hybrid connectivity between the regions. This flexibility means that you neither need to deploy Managed Microsoft AD in the same region as the infrastructure, nor create a separate domain for each region. You can extend the domain to up to four supported regions and easily horizontally scale, by adding or removing regions as needed. To maintain high availability and improve fault tolerance, Managed Microsoft AD deploys two domain controllers to each region in non-overlapping Google Cloud zones.
Forest design models
Managed Microsoft AD supports the following Active Directory forest design models:
Organizational forest: The same forest contains both user accounts and resources, which are managed independently.
Resource forest: A separate forest is used to manage resources.
Restricted access forest: A separate forest contains user accounts and data that must be isolated from the rest of the organization.
How Managed Microsoft AD is different
Managed Microsoft AD differs from a traditional deployment of Active Directory in a number of ways.
When implementing a traditional deployment of Active Directory, you must:
Manually design and deploy your organization's highly-available AD topology.
Run AD diagnostics manually to ensure your domain is healthy, including tracking DNS, replication, authentication, CPU load, and more.
Manually create backup plans and verify your organization's disaster recovery response.
Manually define firewall rules for the network that hosts your AD domain.
Take special care to ensure other servers running on the same network cannot compromise your AD domain.
Manually patch your AD domain controllers.
Make effort to design and implement security best practices, such as time-bound access to the domain administrator account.
Ensure only very trusted users have administrative access to the resources that run your AD domain controllers.
The Managed Service for Microsoft Active Directory helps mitigate the effort required to set up and maintain your Active Directory domains by automating a number of the tasks, such as keeping domain controllers up to date. Managed Microsoft AD also provides a set of best practices to help further ease the administrative effort.
Getting started with Managed Microsoft AD
To get started using Managed Microsoft AD, specify the name of the Managed Microsoft AD domain and the Google Cloud VPC networks where the Managed Microsoft AD domain is authorized to be available. You can access the Managed Microsoft AD domain using virtual machines in your authorized Google Cloud VPC networks, or via on-premises infrastructure and other cloud products that connect to Google Cloud via VPN or Cloud Interconnect.
Managed Microsoft AD provides:
A delegated administrator account. Use the account to manage your Active Directory domain.
Cloudorganizational unit. Use the
CloudOU to create your Active Directory objects, such as users, service accounts, groups, as well as additional OUs. You can apply Group Policy Objects (GPO) to the OUs you create under the
