Sid Nag, Research Vice President at Gartner, said that “as CIOs think more strategically about how to lay the foundations to support a return to growth, it is clear that the move to digital and associated services will play a big role for organizations in the future. Cloud adoption, therefore, becomes a significant means to stay ahead in a post-COVID-19 world focused on agility and digital touchpoints.”
Nag said that “trying to run things on-premises is a thing of the past. The idea of building capital expenditure-heavy datacenters by organizations is going to be a thing of the past.”
