Query: ADARES: Adaptive Resource Management for Virtual Machines   Virtual execution environments allow for consolidation of multiple
applications onto the same physical server, thereby enabling more efficient use
of server resources. However, users often statically configure the resources of
virtual machines through guesswork, resulting in either insufficient resource
allocations that hinder VM performance, or excessive allocations that waste
precious data center resources. In this paper, we first characterize real-world
resource allocation and utilization of VMs through the analysis of an extensive
dataset, consisting of more than 250k VMs from over 3.6k private enterprise
clusters. Our large-scale analysis confirms that VMs are often misconfigured,
either overprovisioned or underprovisioned, and that this problem is pervasive
across a wide range of private clusters. We then propose ADARES, an adaptive
system that dynamically adjusts VM resources using machine learning techniques.
In particular, ADARES leverages the contextual bandits framework to effectively
manage the adaptations. Our system exploits easily collectible data, at the
cluster, node, and VM levels, to make more sensible allocation decisions, and
uses transfer learning to safely explore the configurations space and speed up
training. Our empirical evaluation shows that ADARES can significantly improve
system utilization without sacrificing performance. For instance, when compared
to threshold and prediction-based baselines, it achieves more predictable
VM-level performance and also reduces the amount of virtual CPUs and memory
provisioned by up to 35% and 60% respectively for synthetic workloads on real
clusters.
