Citrix is having to rewrite the products to run from the cloud as cloud native. So far they are struggling to get the management parts done. In the meantime they have born in the cloud competitors plus service providers who run Citrix on-prem versions on AWS and Azure. There doesn't seem to be much of a niche for a Citrix Cloud doing DaaS and the window is narrowing rapidly.
