Hyperledger fabric network on multiple machines/nodes

We are facing issues to deploy our network on multiple machines. We want to deploy our network on local machines and wants the communications between different peers and organizations. So it is possible to use SOLO for communications. If yes then how. and If no then why?

We want to make small networks on 2 to 3 machines and then wants to combine all the small networks to build a giant network. how this will be possible. Looking for help.
