You have an entire A-Class network(127.0.0.0) within a single VM. That makes ~2^24 possible adresses and 2^16 ports. Isn't that enough of a network?

it's more like "Why would you put multiple process on the same instance instead of just using a monolith app, the overhead for IPC / network isn't worth it if you put every process on the same machine"
