# Multi-Instance Setup

# Multi-Instance Setup {#ariaid-title1}

Multi-Instance Setup discovers non-production instances related to a production instance and connects instances to support cross-instance communication and data sharing with various ServiceNow applications.

Cross-instance communication is important for secure data exchange, synchronization, and collaboration between instances and is required to promote and govern applications across environments. Multi-Instance Setup simplifies setting
up cross-instance communication with a single user interface where administrators can configure and monitor non-production instances connected to a controller. Every connection is requested, reviewed, and approved or rejected to help
avoid silent failures or undocumented instance relationships.

## Multi-Instance Setup and Multi-Instance Management {#multi-instance-setup-overview__multi-instance-setup-and-multi-instance-management}

Multi-Instance Setup is built on Multi-Instance Management and simplifies the process of connecting instances but there are some distinctions between the two features:

* Multi-Instance Management is the ServiceNow AI Platform framework that establishes trust between individual instances at the level of a specific application or capability. Configuring Multi-Instance Management trust directly means working with manager and managed instance relationships one application at a time.
* Multi-Instance Setup manages the relationship between a controller and its non-production instances at the environment level, rather than configuring trust per application and capability. Multi-Instance Setup automatically maintains the underlying Multi-Instance Management trust relationships that individual applications rely on. Other ServiceNow applications that need cross-instance trust automatically manage their own per-capability trust profiles.

  Multi-Instance Setup also adds environment types on top of the Multi-Instance
  Management framework, which only distinguishes non-production instances from production instances.

## Multi-Instance Setup workflow {#multi-instance-setup-overview__how-it-works}

From Multi-Instance Setup, administrators can configure cross-instance communication in a few steps:

1. From the production instance, the instance admin sets the instance as the controller.
2. To add non-production instances to the controller, the admin chooses to run a scan that automatically discovers non-production instances or adds them manually and assigns each one an environment type.Multi-Instance Setup
   automatically sends an access request to each non-production instance's administrator.

3. From a non-production instance, the admin of that instance approves or denies the request to manage the instance from the controller.After the admin approves the request, cross-instance communication between the controller
   and that non-production instance is active.
