Isn't levels of abstraction the way technology works? Look at the evolution of the computer and programming languages. What is the alternative? Buy hardware, rent colo space and manage your own machines that die in the middle of the night? The next level up is dedicated servers managed by a hosting provider. The next level up is a virtual machine on the hardware managed by the hosting provider. The next level up is a service provider letting you run processes on a platform they built. These layers of abstraction are needed so that we on a multitude of levels can do what we need to. Does it make sense? Yes but it makes it all too easy to become reliant on the cloud provider for resilient fault tolerant systems rather than understanding how to fulfil the need yourself.
