Cloudflare Services Utilized

9.1 Service Summary

Service	Purpose	Scale Considerations
Workers	HTTP routing, API, authentication	Unlimited requests, auto-scaling
Durable Objects	Connection state, price aggregation, health monitoring	One DO per workload + global aggregators
D1	Workload metadata, customer data, audit logs	Multiple databases for sharding if needed
KV	Routing cache, token cache, price cache	Global replication, ~60s propagation
Queues	Async processing (notifications, billing)	Automatic batching and retry
R2	Artifact storage (logs, workload configs)	Unlimited storage, zero egress
Workflows	Long-running provisioning/termination	Durable execution with retries
Spectrum	TCP traffic routing	Enterprise feature for non-HTTP
Load Balancing	Health checks, failover	Per-workload health monitoring
