I use to additional groups, 'left' and 'right', to split my 'testing',
'staging', and 'production' groups in half. So I can use, say,
--limit 'testing:&left'
to run a playbook against the left half of my testing servers, or
--limit 'production:&right'
to run a playbook against the right half of my production servers.
Or I can have a playbook that runs two plays
---
- name: update left hand side of production
hosts: production:&left
tasks:
- include: tasks/update.yml
- name: update right half of production
hosts: production:&right
tasks:
- include: tasks/update.yml
Because I get to assign hosts to left and right halves in my
inventory, they can be different sizes for testing, production etc.

"All parts should go together without forcing. You must remember that
the parts you are reassembling were disassembled by you. Therefore,
if you can't get them together again, there must be a reason. By all
means, do not use a hammer." -- IBM maintenance manual, 1925
