Re: I'm confused.
Benefit to cloudy DAAS - from the customer's point of view this permits off site or out of office working, but allows us to maintain controls on the data/keep it on-site - for example one of the effects of the pandemic for my organisation was the sudden requirement to hook up thousands of laptops etc that belonged to end users to the network in order for them to be able to run desktop software that was previously safely installed in the office.
To get round the issues this presented, a number of users suddenly had a crash course in using remote desktops as there was no way we could install to end user owned machines and maintain compliance (also it would have taken ages!)
Of course - that was DAAS on _our_ infrastructure - as you say, moving that use case to somebody else's data centre brings its own compliance and security issues...
