Subject Is ActiveMQ good fit for our project?
Date Tue, 16 Feb 2010 22:37:41 GMT


We are starting a new project and wanted some input/feedback to validate if
ActiveMQ is a good fit.

We have a single central server and thousands of remote clients. Clients
maybe located behind a NAT or Firewall. Every now and then we would like to
send a message from central server to a particular client so that client can
initiate a particular task. We don't expect number of messages sent from
central server to client to be frequent.
Any communication between server and client must be secured, preferably via

Because message is sent from server to one client at any given time, we were
thinking of making use of Point to Point Messaging.

For PTP how does receiver get the message? 
Does the receiver poll message queue to check if it has any messages for
him? or Is the message pushed from queue to receiver? If message is pushed,
how does the provider know the IP of client where message needs to be pushed
esp, when receiver is behind router/NAT.  What about SSL if the message is
pushed, would we need SSL certificate for each client?
