Optimizing Hosting Solutions for a JavaScript and Python-Based YOLO Image Detection Web Application

Building a web application that integrates JavaScript front-end, Python backend, and real-time image processing with YOLO poses unique hosting challenges—particularly when prioritizing affordability and simplicity during the early development stages. If you’re exploring hosting options that support these technologies while remaining budget-friendly, this guide offers key insights and recommendations.

Understanding Your Project Requirements

Technology Stack Overview:
– Front-End: Vanilla JavaScript, HTML, CSS
– Back-End: Python server performing custom YOLO image detection
– Image Processing Frequency: Approximately 0.5 images per second
– Storage: Repository for uploaded images
– Database: User data, logs, image metadata

Key Considerations:
– Cost-Effective Hosting: Preference for free or low-cost solutions
– Scalability & Performance: Not critical at the initial phase but should be feasible
– Flexibility & Ease of Deployment: Support for Python and possibly separate backend servers
– Data Storage & Management: Reliable storage options for images and database needs
