What is the difference between Composer business network and Hyperledger Fabric network

Question

I understand that we can deploy multiple Hyperledger Composer Business networks on a fabric network with single Org (or multi org). Is it similar to deploying multiple chaincodes on a fabric network (on one or more channels)? That means, composer network install and composer network start are similar to peer chaincode install and peer chaincode instantiate on fabric?

Answer 1

You are correct, composer network install is similar to peer chaincode install as it installs your business network onto the peer (your business network is the chaincode here) and under the covers performs a request similar to the peer install command. composer network start is similar to peer chaincode instantiate as it makes a request to instantiate the business network chaincode but also performs some extra required activities specific to hyperledger composer.
