Is the application on hyperledger-fabric centralized?

Question

I started learning hyperledger-fabric for creating my own business application but, I still have a question :

In practice, there is only one machine with docker and whole bna, or every member must have his own docker with bna?

If only one, then it turns out to be a centralized application. Am I right?

Answer 1

In practice, you would expect every Org on the network to have at least one peer. Each org would have its own CA server (or cryptogen), and use shared Orderers. It is 1 business network (Definition is embedded in the genesis block). If, as you ask, there was only one Org, it would be centralized.
