Cloud computing is an emerging technology paradigm that migrates current technological
and computing concepts into utility-like solutions similar to electricity and water systems …

Many real world graphs have small world characteristics, that is, they have a small diameter
compared to the number of nodes and exhibit a local cluster structure. Examples are social …

Elasticity can be seen as the ability of a system to increase or decrease the computing
resources allocated in a dynamic and on demand way. It is an important feature provided by …

Recently, we have witnessed many HPC applications developed and hosted in the cloud,
which can benefit from the elastic and diversified resources on the cloud, while on the other …

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 …

In this study, we describe the​ further development of Elastic Cloud Computing Cluster
(EC3), a tool​ for creating self-managed cost-efficient virtual hybrid elastic clusters on top of …

Cloud computing has drawn increasing attention from the scientific computing community
due to its ease of use, elasticity, and relatively low cost. Because a high-performance …

Transient cloud servers such as Amazon Spot instances, Google Preemptible VMs, and
Azure Low-priority batch VMs, can reduce cloud computing costs by as much as 10x, but can …

In this paper, we propose monetary cost optimizations for MPI-based applications with
deadline constraints on Amazon EC2. Particularly, we consider to utilize two kinds of …

Internet of Things (IoT) applications can benefit greatly from cloud-hosted message broker
services that utilize publish-subscribe communications. The operators of IoT cloud-hosted …
