Day By Day

Cloud Computing is one of the emerging technologies in all fields and is called as the type of computing relayed on the internet. The main functions of Cloud Computing are hosting and delivering of various software and services using the internet. Depending on the demands and requirements of the user, the cloud computing affords the main computational resources to users as service. The main computational resources are larger storage space, server with high performance, various operating systems for various platforms and Network. The demand for these resources by the user is increasing day by day with the main drawback of security and is considered as a very serious problem in cloud computing. This paper has surveyed the various concepts related to cloud computing such as, the architecture, types and models for deployment, applications, advantages and disadvantages. The main goal of this paper is to provide a better knowledge about the cloud computing and its issues in the research on various domains.

Cloud computing is an architecture for providing computing service via the Internet.  Use of the term “cloud” is a metaphor for the representation of the Internet used in most systems diagrams.  In this case, the Internet is the transport mechanism between a client and a server located somewhere in cyberspace, as compared to having computer applications residing on an “on premises” computer.  Adoption of cloud computing practically eliminates two ongoing problems in IT service provisioning: the upfront costs of acquiring computational resources and the time delay of building and deploying software applications.  This paper gives an ontological view of the subject in order to serve as a point of reference in the discipline and to facilitate ongoing technical development.

Security Of Iot

The Internet of Things (IoT) is rapidly changing our society to a world where every “thing” is connected to the Internet, making computing pervasive like never before. This tsunami of connectivity and data collection relies more and more on the Cloud, where data analytics and intelligence actually reside. Cloud computing has indeed revolutionized the way computational resources and services can be used and accessed, implementing the concept of utility computing whose advantages are undeniable for every business. However, despite the benefits in terms of flexibility, economic savings, and support of new services, its widespread adoption is hindered by the security issues arising with its usage. From a security perspective, the technological revolution introduced by IoT and Cloud computing can represent a disaster, as each object might become inherently remotely hackable and, as a consequence, controllable by malicious actors. While the literature mostly focuses on the security of IoT and Cloud computing as separate entities, in this article we provide an up-to-date and well-structured survey of the security issues of cloud computing in the IoT era. We give a clear picture of where security issues occur and what their potential impact is. As a result, we claim that it is not enough to secure IoT devices, as cyber-storms come from Clouds.

The Internet Of Things

With the arrival of the Internet of Things (IoT) era and the rise of Big Data, cloud computing, and similar technologies, data resources are becoming increasingly valuable. Organizations and users can perform all kinds of processing and analysis on the basis of massive IoT data, thus adding to their value. However, this is based on data-sharing transactions, and most existing work focuses on one aspect of data transactions, such as convenience, privacy protection, and auditing. In this paper, a data-sharing-transaction application based on blockchain technology is proposed, which comprehensively considers various types of performance, provides an efficient consistency mechanism, improves transaction verification, realizes high-performance concurrency, and has tamperproof functions. Experiments were designed to analyze the functions and storage of the proposed system.

The Internet and emerging technologies are facilitating the creation of new marketplaces designed to address a diverse range of business and societal needs. As companies are utilizing technology to manage their business processes, such a marketplace has emerged that is designed to provide third-party availability of business services delivered via Web services technology, particularly in the context of Cloud Computing. The Web Services Marketplace creates a common trading ground wherein buyers and sellers of business services can come together within a centralized marketplace. However, sellers of business services must provide a mechanism by which knowledge and awareness of the service is created for the buyer and a means by which sellers can effectively compete in the marketplace. The most widely accepted method for accomplishing these tasks is advertising. This study investigates the nascent phenomenon of the advertising of business services within the Web services marketplace, develops a theoretically grounded definition and characteristics of business services offered in the Web Services Marketplace, and develops a model for the effective advertisement of business services offered in the Web Services Marketplace.

Pandemic brought new forms of remote education into the discussion. However, facilitating students' access to good computing infrastructure is not a widespread task. This paper presents a report on the use of computing resources in the AWS cloud by students in the Operating Systems class during the pandemic, from March to July 2020. The use of these computational resources was essential to consolidate some of the concepts covered in the course and, at the same time, to complement the students' knowledge about cloud computing. The results of this survey were very positive. Students said they learned more about the resources available in the cloud, the potential of cloud computing, and how to use it. Besides, they were able to create their remote infrastructure to carry out the work proposed in the Operating System class.

Cloud computing is a technology that allows dynamic and flexible computing capability and storage through on-demand delivery and pay-as-you-go services over the Internet. This technology has brought significant advances in the Information Technology (IT) domain. In the last few years, the evolution of cloud computing has led to the development of new technologies such as cloud federation, edge computing, and fog computing. However, with the development of Internet of Things (IoT), several challenges have emerged with these new technologies. Therefore, this paper discusses each of the emerging cloud-based technologies, as well as their architectures, opportunities, and challenges. We present how cloud computing evolved from one paradigm to another through the interplay of benefits such as improvement in computational resources through the combination of the strengths of various Cloud Service Providers (CSPs), decrease in latency, improvement in bandwidth, and so on. Furthermore, the paper highlights the application of different cloud paradigms in the healthcare ecosystem.
