+## Production Deployment & Zero-Downtime Releases
+
+EpicNext-CMS is engineered for enterprise-grade production environments with zero-downtime deployment capabilities:
+
+1. **Blue/Green Slot Deployments**:
+   - Updates run through containerized slot orchestration (`scripts/docker-update.sh`), ensuring seamless transitions between release versions without dropping requests.
+   - Automatic health check verification (`/api/health`) validates database connectivity, Redis/Valkey status, and RCON liveness before routing production traffic.
+
+2. **Automated Rollback Protection**:
+   - If a post-cutover health check or startup sequence fails, the system automatically triggers a rollback to the previous stable container image and logs the incident.
+
+3. **High-Performance Caching & Rate Limiting**:
+   - Integrates with Redis / Valkey for distributed session storage, global rate limiting, and ephemeral response caching.
+   - Multi-tier anti-DDoS proxy filtering defends against volumetric application-layer abuse with automatic Cloudflare edge-block mirroring.
