Volatile service innvocation
Asynchronous (MOM)
Problems when sender issues request to receiver
asynchronous messaging can solve this
first important data application
SMS
e-mail
Sender side asynchronous requests
Receiver side asynchronous requests
use third party mediators
facility to store, route and transform messages
Synchronous(RPC)
process threads of execution must block waiting in the sender, waiting for a response
RPC solutions to failures need not be as robust as MOM
complex to design
distribution is transparent to the application
connectionless communication
no communication channel or connection needs to be pre configured before any connection takes place
connections need not be dismantled after the communication session has ended
message headers are longer in this

RPC
MOM
