Virtual machine consolidation is attractive in cloud computing platforms for several reasons
including reduced infrastructure costs, lower energy consumption and ease of management …

Application profiling is an important performance analysis technique, when an application
under test is analyzed dynamically to determine its space and time complexities and the …

Heterogeneity prevails not only among physical machines but also among workloads in real
IaaS Cloud data centers (CDCs). The heterogeneity makes performance modeling of large …

A performance model is used for studying distributed Web systems. Performance evaluation
is done by obtaining load test measurements. Queueing Petri Nets formalism supports …

Distributed cache systems are used to store and retrieve frequently used data for faster
access by exploiting the memory of more than one machine, but they appear as one logical …

In this paper, a performance model is used for studying distributed web systems (an J2EE
web application with Oracle backend-database). Performance evaluation is done by …

Visualization techniques are applied to an electric power system transmission network to
create a graphical picture of network power flows and voltages. A geographic data map is …

The paper presents creating web system models. The aim of the work was to develop
models of the distributed Internet system that allow the performance evaluation. From many …

Response time density is obtained in a tandem pair of Markovian queues with both batch
arrivals and batch departures. The method uses conditional forward and reversed node …

Performance isolation is enforced in the cloud by setting to each virtual machine (VM) a
given fraction of each resource type (physical memory, processor, and IO bandwidth) …
