Cloud Architect vs Infrastructure Architect

Are Cloud Architects just a modern version of an Infrastructure Architect?

A traditional Infrastructure Architect would be designing for physical servers, storage and network equipment in a datacenter. Perhaps designing datacenter facilities if required.

Now a days they usually go up the stack to the hypervisor and operating system, maybe even as far as designing technical services such as DNS or Authentication like Active Directory. Sometimes when that happens it might be referred to as a “Platform Architect”.

I suppose when we are talking about IaaS provided by Azure, AWS or GCP then there is some crossover and it’s basically the same role. But when we are referring to PaaS offerings eg. SQL DBaaS, is that still in the realm of infrastructure architect or is that called a “platform” or is that “cloud”?
