Trick to keep in mind+3 XP

Count the layers you still patch: the fewer you patch, the higher up the model you are.

On IaaS you get a machine and look after everything from the operating system upward, including any database you install. On PaaS the provider runs the operating system and the engine, and you bring code or data. On SaaS you just use the finished product. A managed database where you only create tables leaves the engine to someone else.

Read it once, then a question tests whether the trick stuck.
