How relevant do you think on premise solutions will be in the next 5 years?

An ideal world would be hybrid and cloud-agnostic. Telcos are arguably in the datacenter business, therefore on-prem may still make sense to them long-term. Other types of organizations may have legacy reasons to keep a relevant on-prem footprint. Anyway, cost effective cloud usage requires operational processes refactoring and not all organizations are comfortable with it.

I think on-premises solutions will still be around, mostly with larger companies. Considering the new products I've seen coming from Genesys, they will be secondary to cloud solutions.

most of the new things to come are cloud based, AI, chat bot etc, besides it is more agile use the cloud, you can grow faster, move from one building to another. everything is movin to cloud, so do your investment there

On primise will never be taken away believe me. The modern cloud solutions will be a good option or an alternative for services you want to run out of the box with minimum customizations, but it will be on-prem which you will need to get a solution to suite your taste 100%. I am not worried about on-prem to be going anywhere in next 15 years

On premise solution is still suitable for big organizations because of it's suitable TCO over 3 Years, yet there are some factors that will affect this equation in the upcoming two years like the investment in the Cloud,AI and digital solutions which will help into providing more appealing CX, services and faster TTM with less cost.
