The variety and complexity in cloud marketplaces is growing, making it difficult for cloud consumers to choose cloud services from multiple providers in an economic and suitable way by taking into account multiple objectives and constraints. In this paper, we present an extension of CloudSim implementing cloud management functionality to enable the assessment of consumer-oriented brokering sche...

Cloud based development is a challenging task for several software engineering projects, especially for those which needs development with reusability. Present time of cloud computing is allowing new professional models for using the software development. The expected upcoming trend of computing is assumed to be this cloud computing because of speed of application deployment, shorter time to ma...

Cloud computing has given the new face to the distributed field. Two main issues are discussed in this paper, (I) “the process of finding the efficient virtual machine by using the concept of load balancing algorithm”. (II) “Reallocation of the Virtual Machines” i.e. migration of the Virtual Machines when cloud provider is not available with the required Virtual Machines. We have discussed abou...

Cloud computing is a technological advancement in the arena of computing and has taken the utility vision of computing a step further by providing computing resources such as network, storage, compute capacity and servers, as a service via an internet connection. These services are provided to the users in a pay per use manner subjected to the amount of usage of these resources by the cloud use...

With the rapid development of the cloud computing and big data, many data center network are growing more large scale, and the number of servers is increasing at an exponential rate. In this paper, VCG (Vickrey-Clarke-Groves) mechanism was introduced into replica placement. Mapping from replica placement model to VCG mechanism was established and suitable payment function was designed. Data sto...

Cloud data centers consume enormous amounts of electrical energy. To support green cloud computing, providers also need to minimize cloud infrastructure energy consumption while conducting the QoS. In this study, for cloud environments an energy consumption model is proposed for time-shared policy in virtualization layer. The cost and energy usage of time-shared policy were modeled in the Cloud...

Cloud Computing researches involve a tremendous amount of entities such as users, applications, and virtual machines. Due to the limited access and often variable availability of such resources, researchers have their prototypes tested against the simulation environments, opposed to the real cloud environments. Existing cloud simulation environments such as CloudSim and EmuSim are executed sequ...

Cloud Computing is an awesome technology. It has to goahead and annexes the computing world. The development of cloud computing embed its sprouting continually in the recent era. Cloud Computing have contrived clan very lavish comfortable to perform their chore. As it’s fundamental definition says that As You Pay As You Go. In this delving work we talk about the cloud standards and some standar...

In recent years, research has been conducted in the area of large systems models, especially distributed systems, to analyze and understand their behavior. Simulators are now commonly used in this area and are becoming more complex. Most of them provide frameworks for simulating application scheduling in various Grid infrastructures, others are specifically developed for modeling networks, but ...
