Solution Architecture - How is this different from Enterprise and IT Architecture?

There was a gentleman who recently asked me a question in the context of my current job profile. He asked me
"What is your role as a Solution Architect, and how is the Solution Architect's role any different from an IT Architect or an Enterprise Architect?"
I did explain him the differences and the nuances of each type of architecture. But I also promised to post an article on the same. Hence this.

I forgot to cover this as one of the "most (ab)used words" in my previous article. The words "Enterprise Architect", "IT Architect", etc have been highly misused by people. No offense meant - Companies have used this as a "designation" rather than a "role" in some cases. I hence thought of clarifying these so-called ambiguous terms by outlining the differences between each type of architecture in the context of an Enterprise Architecture. (in conformance with The Open Group standards and definitions)

EA - Enterprise Architecture
EBA - Enterprise Business Architecture
EITA - Enterprise IT (EIT) Architecture
EITIA - EIT Information Architecture
EITAA - EIT Application Architecture
EITTA - EIT Technology Architecture
EITSIA - EIT Software Infrastructure Architecture
EITHIA - EIT Hardware Infrastructure Architecture
SA - Solution Architecture

I hope this has been useful.
