It seems to me that Active Service should be a performance/scalability/availability pattern.

An active service gains a degree of autonomy from other services by keeping a copy of the data that would have to be obtained from those services when the first service is invoked.

What reasons are there to do this if not for performance or availability?

Re: Isn't Active Service a performance/scalability/availability pattern?
The active service pattern can be used in performance and scalability scenarios
but it is also a basic pattern to increase the autonomy of services by letting them, well, be active and not passive
