Alluxio
Alluxio is like a super-fast middle layer that sits between your apps and slow cloud storage. It lets your data-hungry programs grab files and data almost instantly instead of waiting for the cloud to respond every time.
It remembers the files your team uses most often and keeps copies close by so everything feels lightning quick.
Alluxio uses DiskSpace S3-compatible object storage as its reliable long-term home for all the data, treating cheap S3 buckets like a giant safe warehouse while it handles the speedy delivery. This setup saves companies a lot of money because they get high performance without having to buy expensive fast disks.
