Best networking practice for services

Hi,

I am designing our network in the cloud. Our network security guy is convinced the best way to do it is to have one VM running all our services with a subnet assigning an IP to each different service. He says we should reduce the number of machines we run down to the minimum. The cloud service in question is IBM cloud. I am hesitant about this because

1) I have have not assigned an IP to a specific service on a single machine before. And

2) I don't have experience with cloud networking.

I would prefer to have one VM per service and assigning different IPs per VM, or failing that, running a group of related services on one VM. What is /r/networking's opinion on this?
