What is your take on commonly accepted practice to physically separate business and presentation layer for reasons like: - security: presentation layer is the only one that gets exposed to the internet and it take hackers more layer to crack. - scalability: easier to scale either/both presentation and business layer if they are separated. - easier division of labor: presentation and business-logic developers only care about their components and they can become more skillful/specialized in their area.
