> I would intuitively go with the decoupled tools every time. Seems to me that the problem is, each of these "decoupled tools" you mention isn't some specialised little awl or hacksaw ("the Unix philosophy..."), nor even a do-anything Swiss Army knife -- but a whole stack of cloud services, "integrations", and administration tools in its own right. A whole machine shop of machine shops. Building your own custom setup out of that is hard. You'll end up with something at least as unwieldy as a really big do-anything single-vendor mega-machine shop stack of cloud services, "integrations", and administration tools.
