By moving appropriate types of files to the cloud, organizations can reduce not only the amount of storage capacity that they need to purchase, but also the operational overhead involved in managing it. In addition, the cloud enables storage capacity to be increased on demand, while charging organizations only for the amount of storage that is actually utilized. Cloud storage will bring many changes to the way enterprises manage storage.

    Cloud Computing and Internet of Things: Issues and Developments

    Proceedings of the World Congress on Engineering 2018 Vol I WCE 2018, July 4-6, 2018, London, U.K. Cloud Computing and Internet of Things: Issues and Developments Isaac Odun-Ayo, Member, IAENG, Chinonso Okereke, and Hope Orovwode Abstract—Cloud computing is a pervasive paradigm that is allows access to recent technologies and it enables growing by the day. Various service types are gaining increased enterprises to focus on core activities, instead programming importance. Internet of things is a technology that is and infrastructure. The services provided include Software- developing. It allows connectivity of both smart and dumb as-a-Service (SaaS), Platform-as–a–Service (PaaS) and systems over the internet. Cloud computing will continue to be Infrastructure–as–a–Services (IaaS). SaaS provides software relevant to IoT because of scalable services available on the cloud. Cloud computing is the need for users to procure servers, applications over the Internet and it is also known as web storage, and applications. These services can be paid for and service [2]. utilized using the various cloud service providers. Clearly, IoT Cloud users can access such applications anytime, which is expected to connect everything to everyone, requires anywhere either on their personal computers or on mobile not only connectivity but large storage that can be made systems. In PaaS, the cloud service provider makes it available either through on-premise or off-premise cloud possible for users to deploy applications using application facility. On the other hand, events in the cloud and IoT are programming interfaces (APIs), web portals or gateways dynamic.

Cloud computing security process should address the issues faced by the cloud users. Cloud Service Provider needs to incorporate the maintenance activity in order to provide the customer's data security, privacy and compliance with necessary regulations. The Elliptic Curve Digital Signature Algorithm (ECDSA) is a public key cryptosystem used for creation and verification of digital signatures in securing data uploaded by the cloud users. Information security concerns have been focused so that identifying unwanted modification of data, deletion of data is identified. Keywords— Cloud Computing,ECDSA,Crptography,RSA, I. INTRODUCTION Cloud computing is internet-based computing, where by shared resources, software and information are provided to computers and other devises on demand. It is a culmination of numerous attempts at large scale computing with seamless access to virtually limitless resources. Cloud Computing providers offer their services according to three fundamental models, namely Infrastructure-as-a- Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS) which is illustrated in figure 1.

    Enhancing Bittorrent-Like Peer-To-Peer Content Distribution with Cloud Computing

    ENHANCING BITTORRENT-LIKE PEER-TO-PEER CONTENT DISTRIBUTION WITH CLOUD COMPUTING A THESIS SUBMITTED TO THE FACULTY OF THE GRADUATE SCHOOL OF THE UNIVERSITY OF MINNESOTA BY Zhiyuan Peng IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE Haiyang Wang November 2018 © Zhiyuan Peng 2018 Abstract BitTorrent is the most popular P2P file sharing and distribution application. However, the classic BitTorrent protocol favors peers with large upload bandwidth. Certain peers may experience poor download performance due to the disparity between users’ upload/download bandwidth. The major objective of this study is to improve the download performance of BitTorrent users who have limited upload bandwidth. To achieve this goal, a modified peer selection algorithm and a cloud assisted P2P network system is proposed in this study. In this system, we dynamically create additional peers on cloud that are dedicated to boost the download speed of the requested user. i Contents Abstract ............................................................................................................................................. i List of Figures ................................................................................................................................ iv 1 Introduction .............................................................................................................................. 1 2 Background .............................................................................................................................

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.
  • 5 Steps to Prepare Your Network for Cloud Computing

    5 Steps to Prepare Your Network for Cloud Computing

    VIAVI Solutions White Paper 5 Steps to Prepare Your Network for Cloud Computing To the novice IT manager, a shift to cloud computing may appear to offer great relief. No longer will their team have to worry as much about large infrastructure deployments, complex server configurations, and troubleshooting complex delivery on internally-hosted applications. But, diving a little deeper reveals that cloud computing also delivers a host of new challenges. Through cloud computing, organizations perform tasks While providing increased IT flexibility and potentially or use applications that harness massive third-party lowering costs, cloud computing shifts IT management computing and processing power via the Internet priorities from the network core to the WAN/Internet cloud. This allows them to quickly scale services and connection. Cloud computing extends the organization’s applications to meet changing user demand and avoid network via the Internet, tying into other networks to purchasing network assets for infrequent, intensive access services, applications and data. Understanding computing tasks. this shift, IT teams must adequately prepare the network, and adjust management styles to realize the promise of cloud computing. Shift in Management Focus With internal hosting, management LAN Switch focuses on the connection between Server Farm Client the LAN and Server Farm. Embracing cloud computing shifts the focus toward the WAN connection. WAN/Internet Internal Hosting Cloud Computing Cloud Provider Cloud computing shifts IT management significantly impact the decisions you make from whether your monitoring tools adequately track priorities from the network core WAN performance to the personnel and resources to the WAN/Internet connection. you devote to managing WAN-related issues.
