Cloud Compute Arbitrage Solution Design

Executive Summary

This document describes the architecture for a Cloud Compute Arbitrage Platform that dynamically selects the best-priced spot/preemptible cloud infrastructure across AWS, Azure, and GCP for temporary workloads, while providing a unified routing layer so end users can access their workloads without tracking infrastructure location.

Key Capabilities

  • Multi-cloud spot instance arbitrage across AWS, Azure, and GCP
  • Real-time price optimization selecting lowest-cost infrastructure meeting workload requirements
  • Unified routing layer for both HTTP and TCP traffic via Cloudflare’s global network
  • Scale to 10,000+ concurrent workloads using Cloudflare’s serverless architecture
  • Full tenant isolation with separate cloud accounts/VPCs per customer
  • Security policy enforcement via Kivera proxy integration
  • Automatic spot interruption handling with graceful notification and termination
