You can use multitude of options:
1. Ports
2. C-nodes
3. TCP communication
4. UDP communication
5. etc.

For TCP communication you can use multiple protocols:
1. Raw TCP sockets with length-prefixed packets
2. HTTP
3. XMPP
4. AMPQ
5. ZeroMQ
6. And many-many-many more

For TCP communication you can use different serialization options:
1. Erlang Binary Term format
2. BERT
3. MsgPack
4. Protocol Buffers
5. JSON
6. And many-many-many more

There are very many different options. Without some more details about
your needs it's hard to select one.
