English abstract:
For providers of composite services, service level agreements
(SLAs) provide a means to guarantee a certain service quality to prospec-
tive customers. Usually, violating SLAs is associated with costs. However,
the means necessary to ensure SLA conformance also generate costs. Of-
tentimes, it is therefore optimal from a business perspective to violate
certain SLAs sometimes, instead of trying for the high (and expensive)
road of always satisfying each one. In this paper we will sketch a frame-
work for the prediction of SLA violations and for determining whether
an adaptation of the process makes sense economically. If this is the case
adaptation actions are triggered, which adapt the composition on either
on instance, structural or environmental level. The ultimate goal is to
implement a closed-loop system, which self-optimizes the costs resulting
from SLA violations.
