Revenue Guard Tech Stack
Serverless by Design
Section titled “Serverless by Design”Revenue Guard is built entirely on the Cloudflare ecosystem. Instead of relying on traditional servers in one or two locations, it uses a “serverless-first” architecture that lives across the globe simultaneously.
[!TIP] Each service is chosen for what it does best: Workers for routing, Durable Objects for strong consistency, and D1 for structured data. The result is atomic inventory management with edge latency.
The Service Mapping
Section titled “The Service Mapping”| Component | Technology | Primary Role |
|---|---|---|
| Compute | Cloudflare Workers | Request routing, authentication checks, and API endpoints |
| State | Durable Objects | Atomic Consistency: The “serialisation point” for each SKU’s inventory count |
| Database | Cloudflare D1 | Persistence: Log of all confirmed reservations and final order history |
| Session | Cloudflare KV | Cache: Fast, global session validation and token storage |
| Security | Turnstile | Bot Protection: Ensuring “one human, one ticket” without friction |
Core Infrastructure
Section titled “Core Infrastructure”Cloudflare Workers
Section titled “Cloudflare Workers”- The Concept: The application’s “Traffic Cop.”
- Role: Handles incoming HTTP requests, verifies Turnstile tokens, and routes valid traffic to the correct Durable Object based on the SKU ID.
Durable Objects
Section titled “Durable Objects”- The Concept: A single-threaded micro-server for atomic state.
- Role: Matches 1:1 with a product SKU. It holds the “true” inventory count in memory. Because it is single-threaded, it acts as a mutex, preventing race conditions (overselling) without needing a central database lock.
- Why it wins: It eliminates the “Check-then-Act” race condition inherent in distributed systems.
Cloudflare D1 (SQLite)
Section titled “Cloudflare D1 (SQLite)”- The Concept: A serverless SQL database at the edge.
- Role: Stores the permanent record. When a Durable Object successfully reserves an item, it asynchronously writes a “Confirmed” row to D1. This separates the high-speed “hot path” (allocation) from the reliable “cold path” (bookkeeping).
Cloudflare Turnstile
Section titled “Cloudflare Turnstile”- The Concept: Essential security for high-demand drops.
- Role: Unlike a CAPTCHA that annoys users, Turnstile verifies humanity in the background. Revenue Guard checks this token before checking inventory, blocking bots at the edge before they can consume database resources.
[!NOTE] This architecture is optimised for flash sales. By moving the “lock” to the edge via Durable Objects, we ensure that a user in Tokyo competes fairly with a user in New York, with the network handling the complexity.
