Service meshes provide service-to-service telemetry that improves relationship inference.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Who owns the CMDB?<\/h3>\n\n\n\n<p>Cross-functional ownership: platform team for operations, domain teams for ownership of CIs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to handle schema evolution?<\/h3>\n\n\n\n<p>Version schemas and run migration jobs; avoid breaking changes in API contracts.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What SLOs are realistic for freshness?<\/h3>\n\n\n\n<p>Start with p95 freshness &lt;15 minutes for dynamic services and tighter for critical infra.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to avoid alert fatigue?<\/h3>\n\n\n\n<p>Aggregate similar alerts, add stabilization windows, and route to owners rather than generic channels.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is CMDB a security tool?<\/h3>\n\n\n\n<p>It supports security by mapping vulnerabilities and exposures, but it&#8217;s not a scanner.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How does CMDB work with IaC?<\/h3>\n\n\n\n<p>IaC can be a source of desired state; reconciliation should detect divergence between IaC and observed state.<\/p>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p>A CMDB is a practical investment to reduce risk, speed incident response, and improve governance in complex cloud-native environments.
