Best Practices (November 2025)

DO

• Use Workers for compute-intensive tasks at the edge
• Implement comprehensive caching strategies
• Configure DDoS protection and WAF rules
• Use Durable Objects for real-time collaboration features
• Optimize global routing for minimum latency
• Monitor edge performance and costs
• Use appropriate storage (KV, D1, R2) based on use case
• Implement security headers and policies

DON'T

• Deploy large applications to Workers (size limits apply)
• Skip security configuration for production
• Ignore edge computing costs and limits
• Use D1 for highly transactional workloads
• Forget to implement proper error handling
• Neglect monitoring and observability
• Overuse edge resources when origin is sufficient
• Skip compliance requirements for data residency
