Hi,

I'm planning on deploying ActiveMQ for delivering event notifications
across different applications and web sites.
The events will be delivered to multiple recipients using publish-subscribe
pattern.
The number of clients is expected to be about 10-20 and they will be
connecting over the Internet.
Message will contain mostly textual data e.g. XML and the typical message
size is estimated to be ~ 50 - 100 bytes.
Message volumes are expected to be moderate.
The clients will be implemented using different technologies, so cross
language interoperability will be important.
In particular, both Java and PHP should be well supported.
XA transactions will not be required, but durable subscriptions and message
expiry are features that may be needed.

Which messaging protocols would be good choices in this case?
Can different clients be allowed to use different protocols to communicate
through the same topic?

Is Apollo currently mature enough to be considered as an alternative to
ActiveMQ?


thanks,

marko
