Serverless Best Practices

Serverless Best Practices

Core Principles

1. Platform First - Default to Cloudflare Workers unless needing:

   • Longer execution time → AWS Lambda
   • Regional presence → GCP Cloud Run
   • Frontend integration → Vercel Serverless

2. JAMstack Architecture:

   • Static assets via Cloudflare Pages/Vercel
   • Dynamic elements through serverless APIs
   • Edge caching where possible

3. Database Integration:

graph TD
    A[Serverless Function] --> B{Query Type}
    B -->|Simple| C[Cloudflare D1]
    B -->|Redis| D[Upstash]
    B -->|PostgreSQL| E[Supabase]

Cost Control

• Set memory/time limits in Wrangler config
• Enable auto-scaling alerts
• Use Cloudflare’s free tier for edge functions
