When you finish this unit, you will be able to:
- Identify which data ingestion method to use.
- Identify how to minimize the risk of technical debt and ensure upgradeability.
Data ingestion methods
ServiceNow supports multiple ways to populate the CMDB. Choosing the right method depends on the data source, volume, frequency, and long-term maintainability.
Common ingestion approaches
- Discovery: automated scanning of infrastructure and applications.
- Import sets / IntegrationHub: structured imports from external systems.
- APIs: programmatic ingestion for custom integrations.
- Manual entry: for non-discoverable or manually maintained CIs.
Minimizing technical debt
- Prefer supported, upgrade-safe patterns over custom scripts where possible.
- Document ingestion pipelines and ownership.
- Align ingestion design with CSDM and CMDB governance standards.
Exam focus: match the ingestion method to the scenario and recognize choices that protect upgradeability.
