You can separate data, processes, and administrative tasks into logically defined domains with domain separation.

1. Managed Service Providers (MSPs) can lease parts of ServiceNow Instance to different organizations.
2. Global companies with unique business requirements for different parts of the world can segment and customize their instances.

Above things can be configured using domain separation.

Domain separation is best for those customers who:

• Need to enforce absolute data segregation between business entities (data separation).
• Customize business process definitions and user interfaces for each domain (delegated administration/process separation).
• Maintain some global processes and global reporting in a single instance.
• Separate data between service providers, customers, partners, or sub-organizations.
• Have minor or moderate process differences among customers.
