Data centers are growing exponentially (in number and size) to accommodate the escalating
user and application demands. Likewise, the concerns about the environmental impacts …

Nowadays, Cloud Computing is widely used to deliver services over the Internet for both
technical and economical reasons. The number of Cloud-based services has increased …

Cloud computing is an ascending technology that has introduced a new paradigm by

Virtualized cloud systems are prone to performance anomalies due to various reasons such
as resource contentions, software bugs, and hardware failures. In this paper, we present a …

When comparing Cloud and non-Cloud Storage it can be difficult to ensure that the
comparison is fair. In this paper we examine the process of setting up such a comparison …

Significant challenges exist for achieving peak or even consistent levels of performance
when using IO systems at scale. They stem from sharing IO system resources across the …

Autonomous management and orchestration (MANO) of virtualized resources and services,
especially in large-scale network function virtualization (NFV) environments, is a big …

In this work, we address problem determination in virtualized clouds. We show that high
