Proactive Fault Tolerance

Cloud computing being a new delivery model has many research challenges. It opens the door to great amount of innovative methods and practices. Many researchers have come-up with novel and efficient fault tolerant solutions for the cloud. With the rapid advancement in internet technology, usage of smart devices and social networking are giving rise to tremendous amount of data and demands resources like never before. Cloud computing delivery model provides solution to the need of the day. The recent advancement in IoT, Edge computing etc, has expanded the scope of visualizing cloud computing with a different perspective. There is a need for re-provisioning the existing components of the cloud model. Most of the research on fault tolerant algorithms, mechanisms and techniques are focused on datacenters. In this paper we propose fault detection and prevention policies for VM creation lifecycle derived from cloud computing patterns

The World

   The concept of implementing e-government systems is growing widely all around the world and becoming an interest to all governments. However, governments are still seeking for effective ways to implement e-government systems properly and successfully. As services of e-government increased and citizens’ demands expand, the e-government systems become more costly to satisfy the growing needs. The cloud computing is a technique that has been discussed lately as a solution to overcome some problems that an e-government implementation or expansion is going through. This paper is a proposal of a  new model for e-government on basis of cloud computing. E-Government Public Cloud Model EGPCM, for e-government is related to public cloud computing.

AbstractInnovative information and communication technologies have reformed higher education from the traditional way to smart learning. Smart learning applies technological and social developments and facilitates effective personalized learning with innovative technologies, especially smart devices and online technologies. Smart learning has attracted increasing research interest from the academia. This study aims to comprehensively review the research field of smart learning by conducting a topic modeling analysis of 555 smart learning publications collected from the Scopus database. In particular, it seeks answers to (1) what the major research topics concerning smart learning were, and (2) how these topics evolved. Results demonstrate several major research issues, for example, Interactive and multimedia learning, STEM (science, technology, engineering, and mathematics) education, Attendance and attention recognition, Blended learning for smart learning, and Affective and biometric computing. Furthermore, several emerging topics were identified, for example, Smart learning analytics, Software engineering for e-learning systems, IoT (Internet of things) and cloud computing, and STEM education. Additionally, potential inter-topic directions were highlighted, for instance, Attendance and attention recognition and IoT and cloud computing, Semantics and ontology and Mobile learning, Feedback and assessment and MOOCs (massive open online courses) and course content management, as well as Blended learning for smart learning and Ecosystem and ambient intelligence.

This article describes how cloud computing has emerged as a strong competitor against traditional IT platforms by offering low-cost and “pay-as-you-go” computing potential and on-demand provisioning of services. Governments, as well as organizations, have migrated their entire or most of the IT infrastructure to the cloud. With the emergence of IoT devices and big data, the amount of data forwarded to the cloud has increased to a huge extent. Therefore, the paradigm of cloud computing is no longer sufficient. Furthermore, with the growth of demand for IoT solutions in organizations, it has become essential to process data quickly, substantially and on-site. Hence, Fog computing is introduced to overcome these drawbacks of cloud computing by bringing intelligence to the edge of the network using smart devices. One major security issue related to the cloud is the DDoS attack. This article discusses in detail about the DDoS attack, cloud computing, fog computing, how DDoS affect cloud environment and how fog computing can be used in a cloud environment to solve a variety of problems.

Cloud Computing is a new way of delivering computing resources and services. It is a model for on-demand network access to a shared pool of configurable computing resources like, networks, servers, storage, applications, and services that can be provided with minimal management effort or service provider interaction. The cloud model is composed of five essential characteristics, four service models, and four deployment models. Healthcare is faster growing way to adopt cloud computing. It is very important for every individual and essential for every country in the Globe. Electronic healthcare systems in the world are moving towards a more accessible, collaborative and more proactive way in reaching out to the public. The delivering of public health solutions can lead to increased efficiencies in health related data. Many nations across the globe have launched aggressive stimulus programs aimed at solving public healthcare problems in efficient way. This review article mainly focus on different ICT based infrastructure facilities available in various hospitals in India, abroad with cost effective manner using cloud computing technologies, services and this will be a best solutions for healthcare systems in rural areas. In this paper analyzed and presented about various cloud service providers, investment in healthcare, IT adoption in Indian Healthcare sector, Major benefits of Cloud-based Patient Management System [PMS], about SADA systems, Top ten cloud storage companies in healthcare and Pros and Cons of EHR systems, comparison of Indian healthcare systems with US system, and various Cloud Simulators.
