Choosing the Right Fractional GPU Strategy for Cloud Providers

Cloud providers can implement fractional GPU access through three main approaches: MIG (Multi-Instance GPU), time slicing, and custom schedulers. MIG emerges as the best choice for production environments due to its strong hardware-level isolation, predictable performance, and excellent billing integration, though it's limited to specific NVIDIA hardware like A100 and L40. Time slicing offers a cost-effective alternative for development environments but lacks strong isolation. Custom schedulers remain experimental and unsuitable for multi-tenant cloud environments due to weak enforcement mechanisms.
