Agreed. VictoriaMetrics is indeed a very compelling offering. The disk-less approach is significantly simpler to operate, which I think is the biggest difference. Running opendata's version yourself has fewer moving pieces, and standard operations become trivial because no single service retains permanent state.
It's a meaningful change in calculation of running yourself vs paying someone to do it for you IMO.
