It is true that a desktop system may not be suitable for transorming million row datasets or processing that is running 24x7 - but that is not the market we are aiming for.

1. Users always work with the latest version, so you only have 1 version to support 2. It would make monthly pricing an easier sell

But I think there are some downsides here, with an app that is solely about data:

1. If user's data has to flow through it, there are privacy, GDPR and intellectual property concerns (for both the SaaS vendor and customers) 2. Latency, since you're going to have to upload data 3. Possibly issues with bandwidth fees (I think most clouds only charge for egress bandwidth, but users are still going to want to download the processed data) 4. Monthly pricing is a big turn-off for a large segment
