Production Deployment

Considerations for deploying Shreder in production environments.

Security

Add authentication middleware:

func authMiddleware(next http.Handler) http.Handler {
    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
        token := r.Header.Get("Authorization")
        if !validateToken(token) {
            w.WriteHeader(http.StatusUnauthorized)
            return
        }
        next.ServeHTTP(w, r)
    })
}

Configuration Management

Use environment variables for configuration:

func main() {
    port := os.Getenv("CACHE_PORT")
    if port == "" {
        port = ":8060"
    }

    peers := strings.Split(os.Getenv("CACHE_PEERS"), ",")

    cache := shreder.NewCacheServer(peers, port)
    cache.Start(port)
}

Docker Deployment

Create a Dockerfile for containerized deployment:

FROM golang:1.23.1-alpine AS builder
WORKDIR /app
COPY . .
RUN go build -o shreder main.go

FROM alpine:latest
RUN apk --no-cache add ca-certificates
WORKDIR /root/
COPY --from=builder /app/shreder .
EXPOSE 8060
CMD ["./shreder"]

Performance Characteristics

• Throughput: Handles thousands of requests per second per node
• Latency: Sub-millisecond response times for cache hits
• Scalability: Linear scaling with additional nodes
• Memory efficiency: LRU eviction prevents memory exhaustion

Monitoring

Monitor your cluster with these key metrics:

# Check node health
curl http://localhost:8060/health

# Monitor cache statistics
curl http://localhost:8060/stats

Next Steps

Consider extending Shreder with:

• Persistent storage backends
• Advanced monitoring and alerting
• Authentication and authorization
• Compression and serialization options
• Multi-datacenter replication
