 - **Snapshot Support**: Point-in-time recovery with configurable intervals
 - **Durability Guarantees**: Configurable sync policies (fsync, async, periodic)
 
+### **Containerized Deployment**
+- **Docker Hub Integration**: Pre-built multi-arch images (amd64, arm64)
+- **Docker Compose Support**: One-command cluster deployment with monitoring
+- **Kubernetes Ready**: StatefulSet manifests with service discovery
+- **Minimal Attack Surface**: Scratch-based images, non-root user
+- **Auto-scaling**: Dynamic cluster membership and load balancing
+- **CI/CD Pipeline**: Automated builds and security scanning
+
 ### **Advanced Memory Management**
 - **Per-Store Eviction Policies**: Independent LRU, LFU, or session-based eviction per store
 - **Smart Memory Pool**: Pressure monitoring with automatic cleanup
