Provisioning resources as a service in a scalable
on-demand manner is a basic feature in Cloud computing
technology. Service provisioning in Clouds is based on Service
Level Agreements (SLAs) representing a contract signed between
the customer and the service provider stating the terms
of the agreement including non-functional requirements of the
service specified as Quality of Service (QoS), obligations, and
penalties in case of agreement violations. On the one hand
SLA violation should be prevented to avoid costly penalties
and on the other hand providers have to efficiently utilize
resources to minimize cost for the service provisioning. Thus,
scheduling strategies considering multiple SLA parameters
and efficient allocation of resources are necessary. Recent
work considers various strategies with single SLA parameters.
However, those approaches are limited to simple workflows
and single task applications. Scheduling and deploying service
requests considering multiple SLA parameters such as amount
of CPU required, network bandwidth, memory and storage are
still open research challenges. In this paper, we present a novel
scheduling heuristic considering multiple SLA parameters
for deploying applications in Clouds. We discuss in details
the heuristic design and implementation and finally present
detailed evaluations as a proof of concept emphasizing the
performance of our approach.
