IaaS: no - you will still be fully responsible for Linux and Windows.

PaaS: yes - they will manage OS (and platform software).

Depends on where you put the line between critical and non-critical.

The majority will go to public cloud.

Now you are mixing up cloud and out-sourcing again.

GM has moved from external IT staff running GM data centers to
internal staff running GM data centers.

No public clod after and no public cloud before.

They have dropped out-sourcing.

It happens.

Out-sourcing has potential for savings due to economies of scale
and the side effect of moving more work from on-shore to off-shore.

But there is always a long way from potential savings to
actual savings.

Based on the article it sounds like the reason behind the
switch was not lack of cost savings but lack of innovation.
