Query: Self-Adaptive Trade-off Decision Making for Autoscaling Cloud-Based
  Services   Elasticity in the cloud is often achieved by on-demand autoscaling. In such
context, the goal is to optimize the Quality of Service (QoS) and cost
objectives for the cloud-based services. However, the difficulty lies in the
facts that these objectives, e.g., throughput and cost, can be naturally
conflicted, and the QoS of cloud-based services often interfere due to the
shared infrastructure in cloud. Consequently, dynamic and effective trade-off
decision making of autoscaling in the cloud is necessary, yet challenging. In
particular, it is even harder to achieve well-compromised trade-offs, where the
decision largely improves the majority of the objectives, while causing
relatively small degradations to others. In this paper, we present a
self-adaptive decision making approach for autoscaling in the cloud. It is
capable to adaptively produce autoscaling decisions that lead to
well-compromised trade-offs without heavy human intervention. We leverage on
ant colony inspired multi-objective optimization for searching and optimizing
the trade-offs decisions, the result is then filtered by compromise-dominance,
a mechanism that extracts the decisions with balanced improvements in the
trade-offs. We experimentally compare our approach to four state-of-the-arts
autoscaling approaches: rule, heuristic, randomized and multi-objective genetic
algorithm based solutions. The results reveal the effectiveness of our approach
over the others, including better quality of trade-offs and significantly
smaller violation of the requirements.
