architecture - Way to communicate between backend server ? -

-

i have work on 3 distinct applications instead of big one. question : "can jms used communicate between different servers (wildfly)" ?

this way can add more servers second application if see take longs process. here simple exemple 15 servers. 5 first app take data , them. 5 second app calculate , last application format them , store them second db.

if second app takes long, able add 3 servers on fly , let them connect first jms q , second jms q.

maybe other suggestion how build ?

thanks

enter image description here

this pretty standard messaging.

might depend on jms server, if use queues, each server should able consume individually , message process.

the bigger issue going design of applications. need stateless message can picked server in order , processed without regard else happening. [of course, if there's shared back-end data provider shared among servers, provide context.]

another issue going transactionality , recovery. if message picked server but, whatever reason, server can't process message, have transaction manager allows roll or have put on queue (either originating 1 or new one) yourself? , happens if message continues fail whatever reason, mean (especially if there additional messages should processed after failed message).

so need consider applications' architecture, otherwise messaging sound solution.
