For example, E-learning, cloud computing, social networking, virtual laboratories, virtual realities, virtual worlds, massive open online courses (MOOCs), and bring your own device (BYOD) are all new concepts of immersive and global education that have emerged in educational literature. One of the greatest challenges presented to e-learning solutions is the reproduction of the benefits of an educational institution’s physical laboratory. For a university without a computing lab, to obtain hands-on IT training with software, operating systems, networks, servers, storage, and cloud computing similar to that which could be received on a university campus computing lab, it is necessary to use a combination of technological tools. Such teaching tools must promote the transmission of knowledge, encourage interaction and collaboration, and ensure students obtain valuable hands-on experience.

Always check docs.netapp.com for the latest. Table of Contents Virtual Desktop Services (VDS) . 1 TR-4861: Hybrid Cloud VDI with Virtual Desktop Service . 1 Virtual Desktop Services (VDS) TR-4861: Hybrid Cloud VDI with Virtual Desktop Service Suresh Thoppay, NetApp The NetApp Virtual Desktop Service (VDS) orchestrates Remote Desktop Services (RDS) in major public clouds as well as on private clouds. VDS supports Windows Virtual Desktop (WVD) on Microsoft Azure. VDS automates many tasks that must be performed after deployment of WVD or RDS, including setting up SMB file shares (for user profiles, shared data, and the user home drive), enabling Windows features, application and agent installation, firewall, and policies, and so on. Users consume VDS for dedicated desktops, shared desktops, and remote applications. VDS provides scripted events for automating application management for desktops and reduces the number of images to manage. VDS provides a single management portal for handling deployments across public and private cloud environments. Customer Value The remote workforce explosion of 2020 has changed requirements for business continuity. IT departments are faced with new challenges to rapidly provision virtual desktops and thus require provisioning agility, remote management, and the TCO advantages of a hybrid cloud that makes it easy

  • Fujitsu's Approach to Platform As a Service (Paas)
    Fujitsu’s Approach to Platform as a Service (PaaS) Shoji Wajima Software as a service (SaaS) has been deployed primarily for general-purpose applications, but recently it has been increasingly used for industrial applications. In addition to being used for existing non-routine tasks, it is beginning to be introduced in individual businesses as part of the systems integration for mission-critical tasks. Although investment in information technology (IT) is starting to show signs of recovery for corporate information systems, a long-term vision still remains hard to achieve. This has resulted in a growing tendency for investment decisions to be made on the basis of concepts such as small-scale rapid development and in-house design/development/operation in order to construct systems that are not contingent on external factors. At the same time, service provider customers are increasing their expectations and demanding not only a simple provision of functionality but also the proposal of a framework that contributes to the success of their business. Using case examples, this paper describes Fujitsu’s efforts to address these evolving market demands by providing a platform as a service (PaaS), where an application development and execution environment is provided as a service. It also introduces our future plans and the services we will provide. 1. Introduction recently in business applications as well. The trends of software-as-a-service (SaaS) At the Fujitsu Group, we are planning to utilization in Japan show that SaaS achieved provide roughly a hundred SaaS applications 20% penetration into businesses in 2009 (or 40% by the end of fiscal year 2010, and nearly half including businesses considering introducing of them will be business SaaS applications (for SaaS).

  • CLOUD INFRASTRUCTURE-AS-A-SERVICE AS an ESSENTIAL FACILITY: MARKET STRUCTURE, COMPETITION, and the NEED for INDUSTRY and REGULATORY SOLUTIONS Kamila Benzina†
    CLOUD INFRASTRUCTURE-AS-A-SERVICE AS AN ESSENTIAL FACILITY: MARKET STRUCTURE, COMPETITION, AND THE NEED FOR INDUSTRY AND REGULATORY SOLUTIONS Kamila Benzina† ABSTRACT This Note examines whether public cloud infrastructure-as-a-service (IaaS) has a market structure that incentivizes a small number of cloud providers to engage in anticompetitive conduct to the detriment of competitors, competition, and ultimately consumers. As cloud IaaS becomes the dominant model for configuring and delivering computing resources in our increasingly cloud-based economy, the U.S. IaaS market is consolidating around a small number of players. These dominant players—Amazon, Microsoft and Google—also have a significant presence in downstream markets, which creates strong incentives for these providers to leverage their IaaS market power to distort competition in the diverse markets that depend on access to IaaS. While there is the potential for IaaS providers to act anticompetitively, the larger challenge is a structural one—ineffective competition, which results in a market structure that incentivizes anticompetitive conduct. Given the increasingly vital role cloud IaaS plays in our economy, as well as in our connected lives, important questions emerge as to whether national regulators should take steps to ensure consumers and competition are protected in the emerging cloud-based economy. This Note gives an overview of the IaaS market and examines whether the cost structure of the market has facilitated, and will continue to facilitate, the dominance of a small number of IaaS providers. It goes on to explore how consolidated control over IaaS incentivizes conduct that is potentially harmful to consumers and competitors in varied other markets that depend on access to IaaS.
