English abstract:
Cloud computing is a newly emerged computing infrastructure
that builds on the latest achievements of diverse research areas, such
as Grid computing, Service-oriented computing, business process management
and virtualization. An important characteristic of Cloud-based
services is the provision of non-functional guarantees in the form of Service
Level Agreements (SLAs), such as guarantees on execution time or
price. However, due to system malfunctions, changing workload conditions,
hard- and software failures, established SLAs can be violated. In
order to avoid costly SLA violations, flexible and adaptive SLA attainment
strategies are needed. In this paper we investigate the application of
autonomic computing to SLA-based resource virtualization considering
a three-layered Cloud based infrastructure including agreement negotiation,
service brokering and deployment using virtualization. For each
layer we exemplify how the principles of autonomic computing can be
applied to achieve component self-management.
