Cloud computing has been widely adopted due to the flexibility in resource provisioning and
on-demand pricing models. Entire clusters of Virtual Machines (VMs) can be dynamically …

Cloud spot markets enable users to bid for compute resources, such that the cloud platform
may revoke them if the market price rises too high. Due to their increased risk, revocable …

We study the performance of standard online learning algorithms when the feedback is
delayed by an adversary. We show that\texttt {online-gradient-descent} and\texttt {follow-the …

Amazon offers spot instances to cloud customers using an auction-like mechanism. These
instances are dynamically priced and offered at a lower price with less guarantee of …

Cloud spot markets offer virtual machines (VMs) for a dynamic price that is much lower than
the fixed price of on-demand VMs. In exchange, spot VMs expose applications to multiple …

In order to keep the costs of operating in-memory storage on the public cloud low, we devise
novel ideas and enabling modeling and optimization techniques for combining conventional …

Public cloud service vendors provide a surplus of computing resources at a cheaper price as
a spot instance. Despite the cheaper price, the spot instance can be forced to be shutdown …

Cloud providers offer several types of Virtual Machines (VMs) in diverse markets, with
different guarantees in terms of availability and reliability. Among them, the most popular …

In this article, we explore the efficacy of dynamic effective capacity modulation (ie, using
virtualization techniques to offer lower resource capacity than that advertised by the cloud …

Many cost-conscious public cloud workloads (“tenants”) are turning to Amazon EC2's spot
instances because, on average, these instances offer significantly lower prices (up to 10 …
