English abstract:
Cloud computing is a promising technology for the implementation of scalable on-demand computing infrastructures. Self-manageable Cloud infrastructures are required in order to comply with users´ requirements specified by Service Level Agreements (SLAs) on the one hand, and to minimize user interactions with the system on the other hand. Adequate resource monitoring strategies and timely detection
of possible user 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 monitored resources,
the energy consumption of the application can be determined
and efficiently managed. Resources are monitored using an
efficient framework that is also capable of mapping lowlevel
resources metrics to user-defined SLAs. The detection
of possible SLA violations is based on the predefined service
level objectives and we utilize knowledge databases to manage
the SLA violations and the energy efficiency objectives. For the
evaluation of our approach, we developed image rendering services,
which exhibit heterogeneous workloads for investigating
the resource (CPU, memory, storage) consumption behaviors
of the applications and to determine the optimal monitoring
intervals. The achieved results show that our architecture is
able to monitor and detect the amount of resources consumed
by the applications, which translates into the amount of energy
consumed by the host.
