Infrastructure as Code & Observability

Reducing log retention can save storage but may remove evidence needed for incident investigation, audit, or troubleshooting. A change should account for system and business needs. What to check Compare proposed retention with existing policy, incident response needs, legal requirements, storage cost, export paths, and recovery access. Recommended...

Moving a service between regions can change latency, data residency, network paths, backups, and failure assumptions. A successful resource plan may not cover these operational effects. What to check Review affected dependencies, data location requirements, DNS and routing, disaster recovery, monitoring, vendor constraints, and user impact....

A monitoring panel may display the last known value even after collection stops. Responders can mistake stale data for a healthy system. What to check Check sample timestamps, collection heartbeat, exporter status, scrape errors, and missing-data behavior. Compare with another source or a known test event. Recommended next step Alert on stale samples...

A change can unintentionally disable a backup job when a schedule resource is replaced, detached, or assigned to the wrong policy. What to check Inspect the plan, affected resource links, schedule timezone, retention policy, last successful run, and alert coverage. Confirm backup ownership with the service team. Recommended next step Preserve a...

Load balancer changes can affect routing, TLS, health checks, client IP handling, and availability across multiple services. What to check Inspect planned listeners, target groups, health checks, certificates, stickiness, timeouts, and affected hostnames. Confirm rollback and service owner approval. Recommended next step Stage and validate the change...

A certificate replacement can affect hostname coverage, trust chain, renewal, and service bindings. Applying a plan without checking dependencies may cause client failures. What to check Review certificate names, issuing authority, secret references, listeners, renewal process, dependent services, and rollback availability. Recommended next step...
