Domain Separation Implementation

Host Multiple Tenants within a Single instance of ServiceNow

Quick Facts

Certification: No

Duration: 3 days

Cost: $2,400


Leverage Sub‑tenancy to Support Multiple Organisations within One ServiceNow Instance

Find out how to take advantage of sub‑tenancy within ServiceNow. Domain Separation allows Managed Service Providers and enterprises to support multiple organisations within a single ServiceNow instance. Domain Separation provides data, process and user interface partitioning to accommodate variations amongst tenants while maintaining the ability to report against and manage the environment as a whole.

The course begins with evaluating whether Domain Separation is warranted given specific use cases. Significant focus is then directed towards developing appropriate domain architecture to support business requirements. Then, during the remainder of the course, students configure a Domain Separated instance for a fictitious company, evaluating and discussing best practices at each step in the process.

The course also discusses the business of the Managed Service Provider (MSP) and best practices around ongoing administration. The following topics are covered in the course, and are reinforced by doing a mini‑implementation at the conclusion of the course:

  • An overview, which provides examples and explicit criteria for determining if Domain Separation is the best way to onboard an organisation to a ServiceNow instance  
  • Precise definitions and terminology used to discuss Domain Separation
  • Architecture of a Domain Separated instance, including how to implement domains and understand implications of a domain hierarchy on process, data, and UI
  • Given a detailed corporate structure, sketch a domain hierarchy that creates process and data relationships
  • Identification of global integration points, including system elements are shared between domains
  • Domain separation of custom tables and process logic to assign records in tables to domains
  • Settings and controls that specify domain visibility and how they affect the user experience
  • Application support for Domain Separation and how to evaluate the level of support
  • Development and management practices to establish and maintain a stable, secure environment that meets business needs

The class features lecture and discussion as well as extensive hands‑on practice and reinforcement delivered in a wide variety of lab activities.
