HN discussionYour linked articles are about immersion cooling, which is "liquid cooling," I suppose, but a very different thing. Do OVH actually use immersion cooling in production? This seems like a "labs" product that hasn't been fully baked yet. OVH _do_ definitely use traditional water-loop/water-block liquid cooling like Google are presenting, described here: https://blog.ovhcloud.com/understanding-ovhclouds-data-centr... a…

HN discussion> For my company, neither egress nor storage cost are the big issue. It’s the API call (PUT) cost. > We are write heavy. Reads are probably 1% but need to be instant for a good UI and API experience. It sounds like the recently released OVH High Performance Object Storage[1] might be a good fit. It has better performance than S3[2], completely free API calls, and $0.015 / GB egress. [1] https://corporate.ovhcloud.co…
