> However, managing granular permissions for hundreds or thousands of functions is very hard to do.

When building a FaaS app from scratch granular permissions are manageable. Functions are small, so it’s easy to reason about the capabilities they need and write tight policies.

I don’t see why this doesn’t scale to a larger FaaS app.

I think the real trick is to avoid the bundling of functions and policies the article suggests people do out of convenience.

I’m working on a practical guide to Lambda and IAM policies here:

It's entirely doable to manage permissions granularly, but it's not the most natural thing to do. It's FAR easier to broaden permissions.

The more functions you have and the more time they've had to morph, the more likely they are to have far greater permissions than they should.
