A few ideas from an article by Microsoft's Roger Wolter on the MS infrastructure support for reliability in connected systems 9 (in MS Architecture Journal, vol 8):
- SOA = connected systems
- services communicate through well defined message formats => reliability = reliability of the communication infrastructure
- message handling between services more complex than client/server because server must make client decisions
- message infrastructures in the MS world: MSMQ, SQLS Broker, BizTalk (also offers data transformation)
- problems:
1. execution reliability (handling volume): different technologies deal with this differently, e.g. stored procedure 'activation' in Service Broker
2. lost message (communication reliability)
3. data reliability

My thoughts and experiments on various computing topics. Thales used to be my domain name, I might yet resurrect it someday.
