  • Data Isolation: Each instance has its own database, ensuring that customer data remains secure.
  • Customization Flexibility: Customers can tailor the platform to their specific needs without interfering with other users.
  • High Availability: The architecture supports redundancy and disaster recovery, ensuring consistent service delivery.

2. Application Layer

The application layer is where the primary functionality of ServiceNow architecture resides. This layer hosts the platform’s wide array of applications, such as ITSM, ITOM, HR Service Delivery, and Customer Service Management (CSM).

Key attributes:

  • Modular Design: Applications are modular and can be deployed independently or in combination.
  • No-Code/Low-Code Development: ServiceNow enables users to create and modify applications without extensive programming skills.
  • Extensibility: The architecture supports custom apps through tools like the ServiceNow App Engine.

3. Database Layer

The database layer is the backbone of ServiceNow Online, storing all data related to configurations, incidents, users, and more. It uses a relational database (RDBMS) that ensures data integrity and efficient management.

Key attributes:

  • CMDB (Configuration Management Database): A critical part of the database layer, the CMDB tracks Configuration Items (CIs) and their relationships.
  • Data Security: ServiceNow employs encryption and role-based access to safeguard sensitive information.
  • Scalability: The database is designed to handle large volumes of data, supporting enterprise-scale operations.

4. Integration Layer
