CloudArb: GPU Arbitrage Platform

Note: This project is just a POC and is not ready for production. No support is provided for this project.

The Story Behind CloudArb

This project started with a simple curiosity about GPU arbitrage. What began as a weekend POC to explore multi-cloud GPU optimization turned into a full-fledged platform that could potentially save AI companies 25-40% on their compute costs.

The Journey:

Got curious about GPU arbitrage across cloud providers

Tweeted about the idea (https://x.com/Siddhant_K_code/status/1946710137046970401)

Built a proof-of-concept over the weekend

Showed the demo to my mentor

Mentor shared Modal's excellent blog post about resource solving

Realized they had already solved this elegantly

Decided to open source the work anyway as a learning experience

CloudArb is an enterprise-grade GPU arbitrage platform that optimizes cloud compute costs for AI companies through real-time multi-cloud resource allocation and automated deployment. The platform leverages linear programming optimization and machine learning to reduce GPU compute costs by 25-40% while maintaining performance and reliability.

🎯 What Problem Does This Solve?

AI companies spend millions on GPU compute, often overpaying by 25-40% due to:

Price variations across cloud providers (AWS, GCP, Azure, Lambda Labs, RunPod)
Spot vs On-Demand pricing differences
Regional price variations within the same provider
Lack of real-time optimization for workload placement

CloudArb solves this by:

Real-time price monitoring across 5+ cloud providers
Linear programming optimization to find the cheapest combination
Automated deployment of optimized configurations
Risk management with quantitative trading principles

🚀 Quick Start

Prerequisites

Docker and Docker Compose
Git
Cloud provider API keys (AWS, GCP, Azure, etc.)

1. Clone the Repository

git clone https://github.com/siddhant-k-code/cloudarb.git
cd cloudarb

2. Deploy with One Command

# Make deployment script executable
chmod +x scripts/deploy.sh

# Deploy to development environment
./scripts/deploy.sh development deploy

3. Access the Platform

After deployment, access the platform at:

Frontend Dashboard: http://localhost:3000
API Documentation: http://localhost:8000/docs
Grafana Dashboards: http://localhost:3001 (admin/admin)
Prometheus Metrics: http://localhost:9090

4. Configure Cloud Providers

Update the .env file with your cloud provider API keys:

# Edit the environment file
nano .env

# Add your actual API keys
AWS_ACCESS_KEY_ID=your_actual_aws_key
AWS_SECRET_ACCESS_KEY=your_actual_aws_secret
GCP_PROJECT_ID=your_gcp_project
# ... etc

5. Create Your First Optimization

# Quick optimization example
curl -X POST "http://localhost:8000/optimize/quick-optimize" \
  -H "Content-Type: application/json" \
  -d '{
    "gpu_type": "a100",
    "gpu_count": 4,
    "workload_type": "training",
    "budget_per_hour": 50
  }'
