What is the nature and description of the request?

Enhance Trustee to support enterprise production deployments through comprehensive infrastructure improvements including high availability, scalability, and production readiness capabilities. The request encompasses storage abstraction with shared state management enabling horizontal scaling and zero-downtime deployments, comprehensive monitoring and audit logging for enterprise compliance, protocol backwards compatibility framework preventing breaking changes, and enhanced administrative boundaries preventing configuration conflicts between operator and runtime management.

Why does the customer need this? (Business requirements)

Production availability: Mission-critical workloads require 99.9% uptime with zero data loss during failures

Horizontal scalability: Enterprise deployments need multiple KBS instances to support thousands of concurrent workloads

Operational visibility: Comprehensive audit logging and monitoring required for compliance and troubleshooting

Zero-downtime operations: Production environments cannot tolerate service interruptions for updates or maintenance

Configuration consistency: Multiple update methods create operational complexity and configuration drift risks

Protocol stability: Client deployments must remain compatible across Trustee server version upgrades

Affected packages or components

• kbs: Storage abstraction, session management, multi-instance coordination
• attestation-service: Protocol compatibility framework, enhanced monitoring
• rvps: Shared storage backend implementation, API integration with storage abstraction
• trustee-operator: Enhanced configuration management and HA deployment support
• OpenShift Routes: Session affinity configuration for immediate HA
• Kubernetes ConfigMaps/Secrets: Shared storage backend for HA
• Prometheus metrics: Enhanced operational visibility and performance monitoring

Technical implementation details

Storage Abstraction Architecture: Pluggable storage interface supporting ConfigMaps (Kubernetes-native), Redis (non-Kubernetes), and database backends (enterprise scale)

High Availability Implementation: OpenShift Route session affinity for immediate deployment, storage-based session sharing for complete HA solution

Protocol Compatibility Framework: Automated testing matrix validating client/server version combinations with CI integration preventing breaking changes

Enhanced Monitoring: Per-connection audit logging, comprehensive Prometheus metrics, structured logging for enterprise log aggregation
