Provider comparison
Amazon Web Services vs Vast.ai
Amazon Web Services
Amazon Web Services is the world's largest cloud provider with 200+ services across compute, storage, databases, ML, and networking. Dominates in enterprise with the broadest global region footprint and the deepest service catalog, but pricing complexity and egress fees add up at scale.
Vast.ai
Vast.ai is a decentralized GPU marketplace where host operators list idle accelerators at market-driven prices - often the lowest spot rates anywhere. The trade-off is variable reliability, no compliance certs, and community-grade support; ideal for cost-sensitive experimentation, fine-tuning, and batch inference where occasional interruption is acceptable.
