JMS: JMS is Java Messaging Service. It's a way to implement asynchronous messaging in Java.
Difference between JMS and RPC: In Remote Procedure Call, the remote procedure is executed and the caller awaits a response from the remote procedure. In JMS, the message sender sends a message and continues processing without awaiting a response from any receivers.
Advantage of JMS: Typically senders and receivers are decoupled from each other, so the system has more availability as a whole since there are more than one points of failure.
