Virtualized networked datacenters (VNDCs) are gaining considerable attention for stochastic
task execution under real-time constraints. However, the problem of efficiently minimizing …

In this paper, we present an approach with the goal to improve the underlying architecture of
cloud systems. For this, we propose UML2Cloud, a framework targeted at modeling and …

Nowadays, cloud computing technologies are commonly used both by the public and private
institutions, so as to save money and computing efforts, by using a network of remote servers …

While energy is directly consumed by hardware, it is the software that provides the
instructions to do so. Energy profilers provide a means to measure the energy consumption …

State-of-the-art cloud simulators in use today are limited in the number of features they
provide, lack real network communication models, and do not provide extensive Graphical …

In cloud environment resources are dynamically allocated, adjusted, and deallocated. When
to allocate and how many resources to allocate is a challenging task. Resources allocated …

During the last decade, the research community has developed different simulation tools to
model and study cloud systems. However, current cloud simulators focus on specific …

Energy preservation is very important nowadays. A large number of applications in science,
engineering, astronomy and business analytics are classified as Bag-of-Tasks (BoT) …

Cloud computing is a paradigm that provides access to a flexible, elastic and on-demand
computing infrastructure, allowing users to dynamically request virtual resources. However …

Energy consumption in Cloud computing is a significant issue and affects aspects such as
the cost of energy, cooling in the data center and the environmental impact of cloud data …
