It's worth noting that Basecamp's architecture relies on vertical scaling, which can get very expensive in the cloud.

    DHH’s preferred architecture is a rails monolith with a single database behind it that you keep scaling vertically. I believe both Hey and Basecamp are still using that architecture.
