Cloudflare vs AWS vs Azure — Feature Comparison Table
Cloudflare, AWS, and Azure offer different strengths across compute, storage, AI, and networking. This table provides a quick side-by-side comparison to help you understand how each platform stacks up.
| Feature / Capability | Cloudflare | AWS (Amazon Web Services) | Azure |
|---|---|---|---|
| Edge Compute / Serverless | Workers — JS/Wasm at 300+ global edge locations. | Lambda — Deep AWS integration, triggers, IAM. | Functions — Integrates with Azure + Event Grid. |
| Object / Blob Storage | R2 — S3-compatible, no egress fees, edge-optimized. | S3 — Highly durable with broad tooling. | Blob Storage — Reliable, integrated with Azure services. |
| Relational Databases | D1 — Serverless SQLite at the edge. | RDS — Scalable, mature, multiple engines. | Cosmos DB — Mature managed database options. |
| Containers | Workers — Supports serverless container-style workloads. | ECS — Deep AWS-integrated container orchestration. | AKS — Kubernetes with strong Azure integration. |
| Sandboxes | Sandbox SDK — Runs untrusted code securely and isolated. | Fargate — Strong isolation; no edge-focused sandbox product. | Container Instances — Isolated containers; no edge sandbox. |
| Workflows | Workflows — Durable orchestration on Workers. | Step Functions — Scalable, mature orchestration. | Logic Apps — Code-first or low-code workflow tooling. |
