It is possible that some outsourcing people like to think about it that way.

But they are totally missing the point.

Cloud and outsourcing are orthogonal aspects.

Cloud is about using another companies hardware.

Outsourcing is about using another companies people.

They can be freely combined.

You can run your own servers with your own IT staff.

You can run AWS instances with your own staff.

You can run your own servers with IBM/TCS/whoever staff.

You can run AWS instances with IBM/TCS/whoever staff.

IaaS is extremely little outsourcing.

PaaS/FaaS/SaaS implies more outsourcing but it is a consequence not the 
goal.

It happens.

But in the end the number are pretty clear.

IaaS public cloud market is growing around 25% per year. And it is
expected to continue so for the next 5 years.
