Let's make something clear...
... this pandemic didn't strike on-premises data centers and turned them off. They keep on humming along just like cloud ones.
The only real problem are the pipes connecting those data centers to the rest of the internet - and many users connections as well to the internet.
Telco lack of investments outside big cities because ROI is measured in years instead of months, and government inertia about building a nation-wide fibre infrastructure for the XXI century means real broadband connectivity too expensive for many companies, and often not available to end users.
Even when such projects were started, some are failing among incumbent fights to maintain a dominant position, and lack of management capabilities to sustain such efforts.
Even if you put all your applications in a shiny-shiny cloud datacenter, it's quite useless if your users have to access it through slow ADSL lines that may have to be shared among family members for work or education. Even FTTC may be slow if you're away from the cabinet enough, or many concurrent users means a lot of cross-talk interference. 4 or 5G with a data cap will help up to a point - and cells can become saturated as well.
That's very different from the 1Gb/s LANs at the office.
And once the connectivity exists, there's little difference if you VPN into a company on-premises network, or access a cloud application.
CTOs and CIOs shoud ask their CEOs to make clear the deploy of a real broadband network is no longer "nice to have". And we can't wait for greedy telcos to deploy them.
