Infrastructure Improvements ​

Monitoring and Observability ​

Status: Planned Impact: High Effort: Medium

Current state: Role-aware internal logs (employee, HOD, administrator, superadmin); service-failure logging with references; admin-level visibility. Logs in Neon; R2 for attachments/avatars.

Improvements (aligned with production observability):

  • Structured log levels: INFO, WARN, ERROR, SECURITY, PERFORMANCE — plus impact/severity field (e.g. npm-style) so dashboards surface high-impact errors first
  • Correlation IDs on every log event: requestId, traceId, userId, ipHash, role, route, timestamp — so failures are traceable
  • Log storage strategy: Monthly audit-log metadata in Neon; blob payload in R2; configurable retention (e.g. 6–12 months or as needed). Index on severity, timestamp, service, correlationId for fast dashboards
  • Anomaly detection layer (locked in plan): abnormal failures per minute, brute patterns, usage spikes, automatic rate-limit — moves from logging to active defense
  • AI-assisted log analysis: Enhancement only; foundation is structured logs so AI reads order, not chaos

Benefits:

  • Visibility + accountability + detectability (production-grade)
  • Better system reliability and faster issue resolution
  • Institutional trust (retention, audit, governance)

Backup and Recovery ​

Status: Planned Impact: High Effort: Low

  • Automated backups: Regular database and file backups
  • Backup validation: Automated backup integrity checks
  • Disaster recovery: Comprehensive disaster recovery plan
  • Point-in-time recovery: Ability to restore to specific points

Benefits:

  • Business continuity assurance
  • Regulatory compliance

Portability and Infrastructure ​

Portability (On-Prem / Non-Edge Migration) ​

Status: Documented; implementation on demand Impact: High for institutional adoption Effort: Medium (conceptual); High if actually migrating off edge

Current state: API is Hono (runs on Node). DB is standard PostgreSQL with Drizzle ORM (no vendor lock-in; Neon is implementation detail). Storage is S3-compatible (R2); can swap to another S3 or local storage. Only edge-native piece is Durable Objects (and cache that uses it).

Important: Portability is not "swap DO for in-memory cache and done." DO provides strong coordination, singleton guarantees, ordered operations. Replacing with a simple memory cache is a consistency model replacement. Be ready to answer:

  • What happens under horizontal scaling without DO?
  • Is memory cache per-instance consistent? Redis replacement?
  • TTL behavior and fallback when cache is cold?
  • Race conditions DO currently protects?
