Open Stack

Vikrant,

Its not mandatory to have floating IPs to access the internet from VM
inside the OpenStack cluster. You can create a router within the tenant and
set-gateway to the external network. The router should be able to do SNAT
to outgoing traffic.

To access the VMs from outside the OpenStack cluster, you need to attach
floating IPs so that you can access the VM via its floating IP from
outside.

In either case, make sure to add security group rules in the tenant SG
accordingly.
