To use the house analogy, it's more like a shed vs a mansion. How many doors are there? How many different keys are there for them, and is there a master key? If you have a shed, there's only going to be one key, for the door. Maaaaaybe a key for the safe inside. If it's an exorbitant mansion with three kitchens and two garages, there's a key for the front door, a key for your bedroom, a key for the safe room, a key to the wine cellar, a key to the garage, a key to the IT closet, a key to the office, a key to the... you get the point.

If it's only ever going to be a shed, there's no need for the infrastructure to support that many keys.

I think it's figuring out where to put them or installing them yourself vs building the locks.

Most things have accounts (database, servers). Are you using separate ones or a global admin?

Thanks, that makes sense. What does IAM offer that a stand-alone service like Keybase doesn’t? At what scale of project does it make sense to use one over another?
