Service Mapping (Top-down) → Recommended for mission-critical application services that require a precise approach using patterns

Tag-Based → Best fit to map cloud-native, container-based, or virtual machine environments

Service Mapping (Connection Suggestions) → Ideal for custom-built applications and leverages application fingerprinting to generate service maps in a timely manner

Dynamic CI Group → Ideal for small application services that can be easily grouped using filters and CMDB queries

In Data Foundations (CMDB + CSDM), an Application Service should be created using an approach that balances accuracy, speed, and maintainability, because the service map becomes the foundation for impact analysis, service visibility, and operational workflows.

Service Mapping (Top-down) is best for mission-critical services because it uses structured entry points and patterns to precisely discover infrastructure, dependencies, and communication paths. This produces high-fidelity maps suitable for strict governance, controlled change, and reliable outage impact analysis.

Tag-Based mapping is best for cloud-native and dynamic environments (containers, elastic virtual machines, and cloud resources) because tags/labels are the most stable identifiers in rapidly changing estates. It aligns well with modern cloud governance where ownership, environment, and service affiliation are expressed through standardized tagging strategies.

Service Mapping (Connection Suggestions) fits custom-built applications because it leverages observed connection data and application fingerprinting to propose likely dependencies. This accelerates service map creation when traditional pattern-first modeling would take longer, helping teams reach usable service visibility faster while still allowing validation and refinement.

Dynamic CI Group is ideal for smaller services where a full discovered map may be unnecessary. It groups CIs using filters and CMDB queries, providing a lightweight way to define “what’s in the service” for reporting, ownership, and basic impact without heavy mapping overhead.
