three components of nsq

NSQ is composed of 3 daemons
nsqd is a daemon that receives, saves and transmits messages to the client.
nsqlookupd is the topological information for management, maintains the status of all nsqd, and provides a daemon that eventually discovers the service.
nsqadmin is a Web UI to monitor the cluster in real time (and perform various management tasks)
