There are two-and-a-half "Cloud" images:
1. Docker Base: this is a "minimum viable Fedora" and is usually run
via 'docker pull' from Docker Hub, where it goes by the name
'docker.io/fedora:22'. Currently it's 186.5 MB. It has dnf, which
depends on Python. I don't think you can remove Python but I believe
there are no Perl or Ruby dependencies in it.
2. Cloud Base: this lives in a Platform-as-a-Service environment and
IIRC is a stripped-down Server. It can host containers but IIRC it can
do more. I've never used Cloud Base but I'm pretty sure it has dnf and
Python.
2.5. Project Atomic: this was released in Fedora 22 but the project
team has decoupled from Fedora's main six-month cycle in favor of a
faster two-week release cycle. It uses rpm-ostree to manage RPMs
rather than dnf so it may not need Python. It's mainly for hosting
Docker containers, and its main end user is the OpenShift
Platform-as-a-Service.

So I don't think there's any risk that an AWS Fedora won't have
Python. However, I believe there's a move to guarantee that all
Python-dependent software runs with Python 3 and only the Python 3
runtime is present on Fedora Cloud products.
