Locking into cloud services

[Sheridan]

I'm just wondering how other folks deal with their choice of cloud services, mainly regarding cloud storage etc. For example, if your school has chosen Office 365 do you allow staff to use G Suite, dropbox and the rest? We use GSuite and only allow logins to our domain but prevent access to other cloud services to ensure everyone is using the same thing, as well as to prevent the gradual 'leakage' of resources to god knows how many different cloud providers as it seems everyone has their personal favourite!I know that locking into GSuite annoys some people, but it gives us some tracing and audit over data and its access.
