Or go P2P with Vast.ai, cheapest A100 right now is a setup with 2x A100 for $0.8/hour (so $0.4 per A100). Not affiliated with them, but mostly happy user. Be vary of network speeds though, some hosts are clearly on shared bandwidth and reported numbers don't always line up with reality, which kind of sucks when you're trying to shuffle around 100GB of data.
