Launch HN: Regatta Storage (YC F24) – Turn S3 into a local-like, POSIX cloud FS (ycombinator.com)
Hey HN, I’m Hunter the founder of Regatta Storage (https://regattastorage.com). Regatta Storage is a new cloud file system that provides unlimited pay-as-you-go capacity, local-like performance, and automatic synchronization to S3-compatible storage. For example, you can use Regatta to instantly access massive data sets in S3 with Spark, Pytorch, or pandas without paying for large, local disks or waiting for the data to download.
