Communication Protocol
Cloudflare Edge Platform Context
Initialize by understanding application and service requirements.
Context query:
{
"requesting_skill": "cloudflare",
"request_type": "get_context",
"payload": {
"query": "What Cloudflare task is needed? (Pages deployment, Workers development, DNS configuration, CDN caching, security setup, load balancing, storage (KV/R2/D1), SSL/TLS, performance optimization, analytics)"
}
}
Workflow
Execute Cloudflare deployment through systematic phases:
1. Analysis Phase
Examine application requirements and Cloudflare service selection.
Analysis priorities:
- Identify application type and deployment needs (static, serverless, full-stack)
- Determine edge computing requirements (Workers, Pages Functions)
- Assess storage needs (KV, Durable Objects, R2, D1)
- Evaluate security requirements (WAF, DDoS, Bot Management)
- Check DNS and domain management needs
- Identify caching and CDN optimization opportunities
- Determine monitoring and analytics requirements
- Validate compliance and data residency needs
2. Processing Phase
Implement edge infrastructure with Cloudflare best practices.
Processing approach:
- Set up DNS records and domain configuration
- Deploy applications to Pages or Workers
- Configure caching rules and page rules
- Implement security features (WAF, firewall rules)
- Set up storage solutions (KV, R2, D1)
- Configure SSL/TLS with appropriate mode
- Create monitoring dashboards and alerts
- Optimize performance with edge rules
3. Delivery Phase
Validate deployment and optimize for production.
Delivery checklist:
- Verify DNS propagation and domain accessibility
- Test Workers and Pages deployments
- Validate caching behavior and cache hit rates
- Check security rules and firewall effectiveness
- Ensure SSL/TLS configuration is correct
- Test storage operations (KV, R2, D1)
- Verify performance metrics and Web Vitals
- Validate analytics and monitoring setup
Best practices:
- Leverage edge computing for global low-latency applications
- Implement proper cache rules to maximize cache hit ratio
- Use security features proactively (WAF, rate limiting)
- Store secrets securely with environment variables
- Optimize Workers for fast execution times
- Use Durable Objects only when strong consistency is needed
- Implement proper error handling in Workers
- Monitor analytics and logs for insights
- Use Wrangler CLI for efficient development workflow
- Regularly review security events and adjust rules
