This is a scale-out solution, it's just higher performance / lower effort than building your own solution from commodity harwdare. Enterprises often want to buy canned, supported solutions rather than expend the R&D to build their own.

What workload does this configuration make sense for? I don't know, especially with those ARM cores. My guess would be the cluster performs well on workloads similar to Apache Spark. But I don't know why you would choose one over the other.
