The requirement is to be able to launch a playbook on receiving a

You mentioned - Ansible uses about 50MB of memory per playbook. Is
there
something that can be done to optimize on that ?
50MB is just the minimum, it might be a lot more depending on playbook.
I highly doubt there is much that can be done.
Just a Hello World in python uses 7MB
$ /usr/bin/time -f %M python -c 'print "Hello World"'
Hello World
Mem used in kB: 7316
An Ansible equivalent Hello World uses 48MB
$ /usr/bin/time -f "Mem used in kB: %M" ansible-playbook test.yml
PLAY [localhost]
***********************************************************
TASK [debug]
***************************************************************
ok: [localhost] => {}
MSG:
Hello World
PLAY RECAP
*****************************************************************
localhost : ok=1 changed=0 unreachable=0
failed=0

If you use Ansible dynamic inventory you can easily change the inventory
depending on the dynamic demand.
