"There is a chance we need to deploy some of our servers on a different
cloud provider or on bare metal servers, in that case the ec2_facts module
will fail."
I would consider constraining the ec2 configuration items to a specific
role and maybe do:
- hosts: ec2_webservers
roles:
- ec2_config
- other_config
And in another playbook, maybe you apply all roles but the ec2 step.
If you wanted a fact on EC2 in a different variable, you could use the
"set_fact" module to assign it from a different source, and leave the other
roles independent.
Altenratively, you could have steps like:
when: ansible_ec2_blah is defined
or "is not defined"
using conditionals.
