Public Cloud: Just More Hype Or A Permanent Change In Computing?

Spring 2021

According to the business press and industry industry buzz, advanced cloud services that use AI and ML have engendered a digital transformation that is elevating IT from a service organization into a central part of all business activity. It seems that every corporation is moving business processes to the cloud en masse. Business continuity planning forms a key use case. But is it really true? Detractors claim that many large corporations still only have 10-15% of their workloads in the public cloud, and argue that corporations do not have the controls in place needed to govern and secure workloads in the cloud they way they can in their private data centers. Which view is correct? In this great debate Johna Till Johnson will argue that migration to the public cloud is both rapid and inevitable, while Greg Ferro will argue that corporations should be cautious and move slowly. Dr. Douglas Comer, Distinguished Professor at Purdue University will moderate and help us navigate this industry debate.

I survived 25 years of Corporate IT in many verticals and wide range of technology and experienced poor IT managers, low quality products, badly designed and deployed solution for the entire period. Yes, I’m bitter but generally got results.
