Conclusions - High-Level model for composite services adaptation - CASAS provides means to Pro-actively adapt composite services (maintain SLA) - Need to do quantitative evaluation Ongoing Work - Coordination layer - Hypothesis – intention propagation provides better alternatives to service adaptation, than optimization solutions using static context information 20

“it might be worth-while to point out that the purpose of abstracting is not to be vague, but to create a new semantic level in which one can be absolutely precise” Edsger Dijkstra http://www.cs.utexas.edu/~EWD/transcriptions/EWD03xx/EWD340.htm 21 l
