Subject Re: Is ActiveMQ good fit for our project?

On the surface it sounds like your project could make good use of ActiveMQ.
Using ActiveMQ is a bit like choosing what your enterprise integration layer
will look like. The advantage of ActiveMQ is that it uses industry proven
messaging (in JMS) and has the convenience of providing many different types
of connectors.

The questions you need to ask are:

   1. Do the messages from server to clients *absolutely have* to arrive at
   the client?
   2. Does the server need acknowledgement that the message was received by
   the client?
   3. Is the messaging a fire and forget or is there some
   synchronous/asynchronous activity going on?
   4. You mention SSL - are you trying to secure the connection (to give the
   client authenticity of the server) or are you trying to secure the messages

All of these issues are handled by ActiveMQ - so it is a good place to
start. It sounds like you want to use JMS queues (assuming you need
point-to-point messaging). And of course there is an SSL option for
encrypting the transport.

I would suggest setting up a small POC (shouldn't take you very long). If
you like it, then it's just a matter of "productionising" it.

If you have any other queries about the details, just come back to this
