There's certainly some overlap, though the Solutions Architects (SAs) are more explicitly focused on publishing solutions (cloud.google.com/solutions). My team is composed of a mix of Google engineers that can (kind of) talk to people, and recovering CXO types from various industries (Finance, Healthcare, etc.). Each of us try to only work deeply with 1-3 customers at once, while SAs are usually focused on more broadly applicable solutions. We all weave in and out depending on personal relationships with customers and individual skill sets, but we're all behind trying to make our customers successful regardless of role or title.
