Distributed computing

“What is Cloud Computing? According to www.webopedia.com this can be defined as an internet based model of computing, where the shared information, software and resources are provided to computers and other devices upon demand.” It is sold on the demand, typically by the minute or by the hour; it is elastic, a user can have as much or as little of a service as they want any given time, and the service is fully managed by the provider. This type of technology is largely used by people on a…

a combination of architectures, has become the focus of efforts to accelerate the simulation of particle methods. The GPU was initially designed to accelerate graphics processing, nevertheless, from the mid-2000s, it becomes a more generalized computing device that promises accelerate codes that demand high computational power at lower cost. Despite the known challenges to speedup linear system solutions using GPU, in 2011, Hori et al. cite{Hori-2011} developed a GPU-accelerated version of…

According to the article, A History of cloud Computing, the fundamental principle of cloud computing is that to “encourage and promote virtual work environment over the existing physical one.” This principle followed for public cloud computing as well. The only difference between public and private is that public cloud is an open system. Therefore, anybody from anywhere in this world can access the storage or software that is available for free or pay a small subscription fee. Another difference…

2. Computing services provided by third parties that operate on AWS • These services tend to offer functionality that enables to build applications of a type that AWS does not strictly offer. Example: AWS offers some billing capability to enable users to build…

environment, cloud computing and virtualization are the cost effective technologies that are striving in order to maximize speed and agility of IT operations. Cloud computing is a network-based platform for sharing computations and resources. Cloud computing is based on a group of virtualised computing resources. Virtualization is defined as the ability to run multiple operating systems on a single system and share underlying hardware resources. Based on virtualization, cloud computing allows…

This phenomenal technology cloud computing has expeditiously evolved in the field of Information Technology. Cloud Service Providers (CPS) have brought diverse transformation changes in cloud computing. This technology has formed new opportunities /haven for criminal activities. The paper has used a descriptive literature review to determine issues that are at present affecting digital investigations. There are several issues that influence the preservation, acquisition and data acquisition of…

continues to evolve and become faster with each passing year, the ability has emerged for companies to cut costs by offloading their networks to companies who host these services over the Internet. This practice has widely come to be known as Cloud Computing. The benefits of such a service are many, but it does come with its own risks. Those who take advantage of such services are exposed to various attacks utilizing the Internet. These potential attacks include, but are not limited to, web…

Abstract Cloud computing is a network based model to provide convenient, on demand and pay per user access to a set of shared resources. Currently cloud computing is in early stages and facing the threats and risks which include security, data leakage, insecure interface and inside attacks. Concept of cloud computing is not new for computer users; it has been in use for decades. In early days of computing a single computer was shared by many users (companies). Another analogy for cloud computing…

1. INTRODUCTION Ubiquitous computing (or "ubicomp") is a concept in software engineering and computer science where computing is made to appear anytime and everywhere. In contrast to desktop computing, ubiquitous computing can occur using any device, in any location, and in any format. A user interacts with the computer, which can exist in many different forms, including laptop computers, tablets and terminals in everyday objects such as a fridge or a pair of glasses. The underlying technologies…

Computers, on a general term have always been considered as a vital source for improving any business’s performance and are meant to contribute in growth and development. Previously it was considered that computers are only used for the computational tasks like rapidly multiplying large numbers. But later it came to the knowledge that computers are not fundamentally number crunchers. They are symbol processors. Computers can help in storing, organizing and transforming the information in a…
