Distributed systems consist of several heterogeneous computing devices. In such systems, the total cost of ownership (TCO) includes capital expenditure such as purchasing of equipment like servers, switches, etc. and operational expenditure such as human salary, electricity bills, etc. Thusly, power consumption is a big portion of operational expenditure. The high rate of power wastage is directly...
Systems-on-a-chip (SoC) represents a rupture on the traditional HPC infrastructure and started to be adopted together OS-level virtualization to provide services in Fog and Edge computing scenarios. In this work, we analyzed the performance of OS-level virtualization solutions - Linux Containers (LXC) and Docker - for HPC activities running in SoC systems in order to discover how OS-level virtualization...
In today's cloud computing platforms, more and more users are now working or collaborating in multi-cloud environment, in which collaborators, clouds, computing nodes may belong to different institutions or organizations. Those different organizations might have their own policies. Security is still a big concern in cloud computing. To help cloud vendors and customers to detect and prevent from being...
Analyzing the behavioral patterns to maintain the workload in cloud computing is very important. There are number of cloud data centers that have the facility to maintain this. But this paper has provided the approach for resource utilization based on two metrics, energy and cost function. This approach works within the workload which helps to understand the relationship between users and servers,...
Cyber culture of the smart university creates the social significance of technological leadership. Internet and cyberspace change all the processes of life of each person. It is necessary to create a new market-oriented model of scientific and educational processes within the Smart Cyber University (SCU). The concept integrates the achievements of classical universities, technological cyber culture,...
Cloud computing is an emerging technology which enables the cloud users to access the computing resources without having to pay huge capital expenses to scale up the IT infrastructure and reduces the management cost, in both hardware and software. A cloud introduces a resource rich computing model with features such as flexibility, pay per use, elasticity, scalability, and others. In this context,...
Cloud computing is a remarkable improvement in the digital landscape that has changed the way of Information Technology solutions are delivered and how end-users put them to use. The cloud computing environment is growing with numbers of cloud service providers and cloud customers. In this scenario, the main confront for cloud customer is to choose ideal service provider among similar services offered...
Performance measurement has become a vital factor especially in the area of cloud computing. Performance of private cloud becomes a matter of concern when it comes to maintaining the performance parameters at desired and controlled levels. To address this issue, in this paper, we analyze and compare the performance parameters like CPU usage, average load, memory usage and read/writes per second with...
Cloud Computing has become popular nowadays. Cloud providers with scalable infrastructures can offer cloud-based services which reduce investment of organizations and diminish most of their operational costs. Therefore, traditional services need to be renovated in the spirit of cloud environments. In this paper, Decision Support-as-a-Service (DSaaS) which is a cloud-based decision support system is...
Cloud computing is a promising computing model that enables convenient and on-demand network access to a shared pool of configurable computing resources. The first offered cloud service is moving data into the cloud. data owners let cloud service providers host their data on cloud servers and data consumers can access the data from the cloud servers. This new paradigm of data storage service also...
CVSS (Common Vulnerability Scoring System) is a framework scoring IT vulnerabilities. CVSS is composed of three metric groups: Base, Temporal, and Environmental. Although, the environmental score which gives risk of vulnerabilities in network environment of each user should be used for prioritizing actions, only base score is currently used. One of the reason for unused of environmental score is hard...
