Cloudera drops 40% after CEO Tom Reilly leaves, forecast cut

I know nothing about their hosting, but it seems that for what they do hardware / cloud costs could be the single biggest expense. Especially if they don't have optimal multi-tenant practices, orchestration and job scheduling, etc

Other large costs (which for less compute intensive SaaS companies like marketing or productivity or whatever would be the biggest ones)

Enginers

Ad/marketing budgets

Sales / account managers (note that not all SaaS is as "self serve" as it purports to be)

If with revenue for year 2020 estimated between 745 and 768 million dollars they are still losing money then what are their operating costs?

I am not familiar with how software as a service companies operators but if they are not manufacturing anything then their cost must be mainly development and operator salaries, and rent and such like. So what else is the money spent on?

AWS? Google Cloud?
