I happen to work with both folks who hold the title "Architect" and others "Designer". In practice there's often overlap in skills in those roles. In my experience there are different types of architect, some focused on infrastructure, perhaps the "topology" you're referring to and some focusing on the solution. The solution architect tends to focus on delivering business solution and capability while the designer is focused on software implementation.
