which approach works better depends on your financial situation and your existing setup. if you have money you can invest, then your approach works. if you have more time than money then invest the time instead. when you have built up your servers over the years, when building a new product, you can also do it quickly because the services you need are already running, and firing up a new database or a new server takes just as long as it takes to set up a managed service. but it doesn't add any cost.
