English abstract:
Cloud computing is a promising paradigm for the implemen-
tation of scalable on-demand computing infrastructures. Self-manageable
Cloud infrastructures are required in order to comply with users' re-
quirements speci ed by Service Level Agreements (SLAs) on one hand
and to minimize user interactions with the system on the other hand.
Adequate SLA monitoring strategies and timely detection of possible
SLA violations represent challenging research issues. In this paper we
present DeSVi|an architecture for detecting SLA violations through
resource monitoring in Cloud computing infrastructures. Based on the
user requests DeSVi allocates necessary resources for a requested service
and arranges its deployment on a virtualized environment. Resources
are monitored using an e cient framework that is also capable of map-
ping low-level resources metrics to user-de ned SLAs. The detection of
possible SLA violations is based on the prede ned service level objec-
tives and we utilize knowledge databases to manage the SLA violations.
Knowledge databases are implemented using techniques like case-based
reasoning, where reactive actions are de ned based on the past system
experience. For the evaluation of our approach, we developed image ren-
dering services, which exhibit heterogeneous workloads for investigating
the optimal monitoring interval of SLA parameters. The achieved re-
sults show that our architecture is able to monitor and prevent SLA
violations considering di erent costs, measurement intervals, and het-
erogeneous workloads.
