Some differences are :--
(1)Services are used for the Business logics to achieve some specific task
      and  Events are Used specially for the some kind of Validation
before performing Business oriented task. but in the Events we can also
perform every         thing that we can done in Services. but the Best
practices says that you should separated Business Logics and validation
or conversion related logics          to avoid code complexity and
increase readability.
(2) Services return Map whereas Events return String but not Map.
(3) Service definitions are loaded when you start the server and in each
time when any changes in service definition not in implementation(when
services     implemented in miniLang not in java) you should have to
reload the services means restart the server. but for the Event you
should have to give path         where this event exist in controller in
request-map not need to restart the server(when in miniLang).
(4) we can call service inside Event but we can not call Event inside
Service.

hi Popo,

Major difference between service and event is that service perform
transaction rollback if any error occur at the time of transaction but in
event not.

Thanks

Hi ,
 We use events to shear the unwanted load from service engine. The additional tasks are performs in events such as validation checking etc. 
There are main four difference between event and services that are: 
1. Service tack map as an input and gives map as output, while events tack map as input and gives string as output .
2. Session related tasks are performed in events .
3.We can call a service from an event, but we not call any event from service .
4.We use services in outer world while, we not use uses the events that is events are application specific.
