Transparency, control, compliance
Today’s companies face the challenge of reliably identifying, controlling, and using their increasingly complex IT landscapes in a compliant manner. With its Discovery, CMDB, and Software Asset Management modules, ServiceNow offers an integrated solution that creates transparency, minimizes risks, and increases potential savings. Discovery plays a central role in SAM in particular, because SAM can only deliver its full benefits with an up-to-date and accurate database.
ServiceNow classifies the three modules as follows:
- Discovery: ITOM → ITOM Visibility → Discovery
- CMDB: Extend ServiceNow AI Platform Capabilities → Configuration Management → Configuration Management Database
- SAM: ITAM → Software Asset Management
This classification shows that the modules originate from different areas, but only achieve their full effect when used in combination.
ServiceNow Discovery: The basis for true transparency in your IT
ServiceNow Discovery automatically identifies your entire IT infrastructure, both on-premises and in the cloud. The module recognizes devices, systems, applications, and services such as:
- Servers, switches, routers
- Databases and middleware
- Applications and their dependencies
- Cloud resources such as AWS, Azure, or Google Cloud
ServiceNow Discovery performs regular scans, detects changes in real time, and collects all relevant information about configuration items (CIs). This data flows directly into the configuration management database and forms the basis for many other processes.
What ServiceNow Discovery offers:
- Automatic detection of the actual IT landscape
- Up-to-date inventory data without manual maintenance
- Visibility across on-premises, cloud, and hybrid environments
- Early identification of deviations and risks
Discovery thus creates a level of transparency that cannot be achieved manually and is indispensable for CMDB and SAM.
CMDB: The central source of IT knowledge
The Configuration Management Database is the central storage location for all IT components and their relationships. It makes the data obtained through discovery usable and is thus the basis for automation, resilience, and service quality.
ServiceNow Discovery provides the following for the CMDB:
- Automatic data maintenance instead of time-consuming manual entries
- Up-to-date and accurate CIs
- Relationship mappings, e.g., server ↔ database ↔ application
- A robust database for service mapping, impact analysis, security operations, and change and incident management
Without discovery, the CMDB often remains incomplete and thus loses its strategic value. Only when the CMDB contains up-to-date, accurate, and complete data can it support decision-making and enable automation.
SAM: Control, compliance, and optimization
ServiceNow Software Asset Management uses information from Discovery and the CMDB to analyze software inventories, licensing models, and usage patterns. The goal is to reduce economic risks and ensure compliance. ServiceNow Discovery is a central data provider in this process.
What Discovery detects for SAM:
- Installed software on servers and clients
- Cloud-based software, e.g., Microsoft 365 or SaaS applications
- Unlicensed or unauthorized software
- Usage patterns for license optimization
SAM uses this raw data to:
- Check license requirements
- Identify compliance violations
- Detect over- and under-licensing
- Optimize license models
- Reduce contract costs
Without Discovery, SAM relies on incomplete or outdated information and cannot provide reliable compliance or cost analyses.
Interaction: Why Discovery, CMDB, and SAM are inseparable
Only the interaction of ServiceNow Discovery, CMDB, and Software Asset Management creates a holistic view of hardware, software, and services in a company—and thus a sound basis for IT governance and cost-effectiveness.
- Discovery recognizes the actual IT landscape.
- CMDB stores and structures this information.
- SAM evaluates economic and legal aspects of the software landscape.
Based on this shared database, companies can not only map their IT transparently and reliably, but also control it in a targeted manner: from automation and compliance to the optimization of licensing models. The result is a modern, efficient, and future-proof IT landscape in which decisions can be made on a sound basis and costs can be controlled sustainably.
