Configuration Management

Process

Step 1: Define CMDB Scope

CI Type	Examples	Priority
Infrastructure	Servers, VMs, containers, network devices	High
Applications	Services, databases, middleware	High
Endpoints	Laptops, mobile devices	Medium
Cloud resources	Instances, storage, networking	High
Licenses	Software licenses, SaaS subscriptions	Medium

Step 2: Design CI Schema

Attribute	Required For
CI ID	All (unique identifier)
Name	All
Type/Class	All
Owner	All
Environment	Servers, Applications
Dependencies	Applications, Services
SLA tier	Services
Cost center	All

Step 3: Map Relationships

Relationship	From → To	Purpose
Runs on	Application → Server	Impact analysis
Depends on	Service → Service	Dependency chain
Managed by	CI → Team	Ownership
Licensed by	Application → License	Compliance

Step 4: Automate Discovery

Method	What It Finds
Agent-based	Installed software, hardware config
Network scan	Connected devices, open ports
Cloud API	Cloud resources, tags, relationships
Service mesh	Service dependencies, traffic patterns

Step 5: Enable Impact Analysis

When a change is proposed:

1. Identify affected CI
2. Traverse dependency graph
3. List all downstream services/users impacted
4. Calculate risk score based on CI criticality

Step 6: Maintain Data Quality

Check	Frequency	Target
Completeness	Monthly	> 95% required fields populated
Accuracy	Quarterly	> 90% match reality (spot check)
Freshness	Monthly	> 90% updated within 30 days
Orphan CIs	Monthly	< 5% CIs with no relationships

Output Format

## CMDB Design: [Scope]
### CI Types: [table with schema]
### Relationships: [dependency model]
### Discovery: [automation approach]
### Quality: [metrics and targets]

Quality Checklist

• CI types cover critical infrastructure and applications
• Relationships enable impact analysis
• Discovery automation reduces manual maintenance
• Data quality metrics are tracked
• Change management integrates with CMDB

Edge Cases

• For cloud-native environments, treat infrastructure as ephemeral
• If starting from scratch, focus on critical services first
• For hybrid environments, ensure cross-platform visibility
