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. -

Security Services Using ECDSA in Cloud Computing
Volume 4, Issue 5, May 2014 ISSN: 2277 128X International Journal of Advanced Research in Computer Science and Software Engineering Research Paper Available online at: www.ijarcsse.com Security Services using ECDSA in Cloud Computing S.Sathish* D.Sumathi P.Sivaprakash Computer Science and Engineering Computer Science and Engineering Computer Science and Engineering Jaisriram Group of Institutions, India PPG Institute of Technology, India PPG Institute of Technology, India Abstract— Cloud computing security is the set of control-based technologies and policies designed to comply to the rules and regulations framed by the provider team to support and protect information, data applications and infrastructure associated with cloud computing use. 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. -

The Cloud-Enabled Data Center
A Revolutionary Technology Extending the Ultra-Broad Functionality of Ethernet White Paper May 2013 The Cloud-Enabled Data Center The Cloud-Enabled Data Center Introduction A growing number of organizations are adopting some form of cloud computing to meet the challenges of rapidly deploying their IT services and addressing their dynamic workload environments while maximizing their IT return on investments (ROIs). Cloud computing gives users the ability to access the IT resources faster than traditional and virtual servers. It also provides improved manageability and requires less maintenance. By deploying technology as a service, your users access only the resources they need for a specific task, which prevents you from incurring costs for computing resources not in use. In addition, developing a cloud-enabled data center can improve operational efficiencies while reducing operational expenses by 50%. Panduit, the leader in Unified Physical Infrastructure offerings, and IBM, a pioneer in delivering cloud computing solutions to clients, have joined forces to deliver optimized, custom and preconfigured solutions for the cloud- enabled data center. This white paper describes how network, storage, compute and operations are important factors to consider when deploying private and public cloud computing in the data center. Specifically, it examines integrated stack/pre- configured and custom cloud deployments. It also explains the importance of the physical infrastructure as the foundation in successful cloud deployment and maintenance. Finally, it showcases how IBM’s depth of experience in delivering systems and software for cloud solutions when combined with Panduit’s physical infrastructure expertise, provides a tremendous impact on room-level data center environmental and new-age topology. -
Rclone VFS and Mergerfs Setup
Rclone VFS and MergerFS Setup This guide is for advanced users only and it serves as a guide for you to use rclone and mergerFS. The files here are the recommended settings for our slots and will subject to change whenever there are new configurations that are appropriate for the slots. Furthermore, USB is not responsible for any data loss or application errors due to this setup should you proceed and will not provide official support for it due to the large volume of variables and different configurations possible with rclone and mergerFS. You may visit the community discord server or the software's respective forums for assistance. Please make yourself aware of the Ultra.cc Fair Usage Policy. It is very important not to mount your Cloud storage to any of the premade folders, this creates massive instability for both you and everyone else on your server. Always follow the documentation and create a new folder for mounting. It is your responsibility to ensure usage is within acceptable limits. Ignorance is not an excuse. Please do not mount to any of the default directories such as: files media bin .apps .config www /homexx/username/ or any pre-created directory found on your Ultra.cc Slot This section will teach you how to set up a rclone VFS mount and MergerFS on Ultra.cc slots, and it assumes the following: You have a working rclone setup, especially correctly configured remotes of your preferred cloud storage provider. In this tutorial, we'll be using Google Drive. If you use another cloud storage provider, change the flags that are appropriate to your setup and visit rclone documentation for more information. -

Comparison of Availability Between Local and Cloud Storage Leviathan Security Group
Comparison of Availability Between Local and Cloud Storage Leviathan Security Group limitless innovation. no compromise. Introduction The U.S. National Institute for Standards and Technology denes cloud computing as having ve essential characteristics: on-demand self- service for provisioning, network access, the use of virtual machines to provide servers, rapid elastic provisioning and release of servers, and metering capability on the service provided.1 This paper seeks to answer whether, from the perspective of availability of data, especially in the face of natural or manmade threats to data and access, cloud computing is able to provide a greater benet than local data storage. For the purposes of this discussion, local data storage will include arrangements where data is kept on business premises or in a nearby datacenter, such as a colocation facility or other rigidly-provisioned resource. We will rst examine the signicant dierentiator that cloud computing provides in this space, and then examine dierent scales of threats to availability to see whether local data storage or cloud data storage fares better against known historical threats. 2 The Cloud Dierentiator: Geographic Redundancy At its heart, cloud computing and cloud storage are exactly the same as computing and storage provided through a datacenter or SOHO server; the cloud is made of computers. The dierence between cloud- based storage and local storage is that using cloud-based storage allows replication between separate geographic regions. Indeed, the key feature of -
