2. Repeatable scaling and failover

• Scripts automate election tuning, priority, and hidden member roles.
• Autoscaling policies align compute and storage with demand signals.
• Cross‑region placement defined for latency and failure domain diversity.
• Health probes trigger orchestrated restarts and resync with minimal impact.
• Capacity modeled with headroom for bursts and maintenance events.
• Playbooks encode step order to reduce error during stressful incidents.

3. Policy and secrets management

• Centralized secrets delivery with rotation and short‑lived credentials.
• RBAC and ABAC ensure least privilege across teams and services.
• Encryption enforced at rest and in transit with FIPS‑ready ciphers.
• Policy checks run in PRs and pipelines to block unsafe configs.
• Drift detection alerts on manual changes outside automation lanes.

2. Image, security, and resource controls

• Images built minimal, scanned, and signed for supply chain integrity.
• Resource requests and limits tuned to memory and working set demands.
• PodSecurity admission enforces non‑root, caps, and FS settings.
• NetworkPolicies confine traffic to app tiers and admin channels.
• TLS, SCRAM, or X.509 applied for mutual trust across components.
• Registry governance ensures provenance and rollback options.

3. Day-2 operations with operators

• Operators encode upgrades, scaling, and failover tasks as CRDs.
• Rolling updates respect elections, replication, and read availability.
• Backups scheduled as Kubernetes Jobs with retention policies.
• Metrics and logs shipped via sidecars to central observability.
• Repair routines handle PVC moves, resyncs, and node drains.
