ServiceNow follows asingle-instance, single-tenant architecture,nota multiple-tenant architecture. This means:
Single-Instance:
Each ServiceNow instance is aunique, independent environmentfor a customer.
All customers have their own dedicated instance with their owncustom configurations, data, workflows, and applications.
ServiceNow instances are hosted in amulti-instance cloud modelrather than a multi-tenant model.
Single-Tenant Model (Multi-Instance Architecture):
Unlikemulti-tenant architectures(where multiple customers share the same application and database), ServiceNow provideseach customer with a separate, isolated instance.
Thisensures data security, performance isolation, and customization flexibility.
Each instance has its owndata storage, configuration, and upgrade schedule, reducing risks associated with shared environments.
Why ServiceNow Uses Multi-Instance Instead of Multi-Tenant:
Security & Data Isolation:Since each customer has an independent instance, there isno risk of data leakagebetween tenants.
Customization & Flexibility:Customers cancustomizetheir instance freely without affecting others.
Performance & Scalability:Each instance can bescaled independently, ensuring optimal performance.
ServiceNow does NOT use a multiple-tenant architecture.
ServiceNow follows a single-instance, single-tenant (multi-instance) model.
Each customer has a dedicated instance with isolated resources and configurations.
A multi-tenant architecturemeans multiple customerssharethe same application/database with logical separation, which is NOT the case in ServiceNow.
ServiceNow instead provides separate instancesfor each customer, meaning it isnota true multi-tenant system.
