Some of the key benefits of DaaS include: • Low deployment and licensing cost • Enhanced security as all data and applications are stored on cloud • Simple to use as the infrastructure management and maintenance is taken care by the provider • Agile and flexible deployment www.hexaware.com | © Hexaware Technologies. All rights reserved. 1 Introduction As the world moves to a virtual office environment, many organizations are seeking the possibility to let their employees work from remote locations. The deployment of a remote desktop solution thus becomes imperative and necessary. This is further accelerated by the cloudification journey that these organizations envision and thus the choice of virtual desktop solution is a critical decision to make. With many options available in the market, with multiple benefits and disadvantages, the organizations need to focus not only on their needs, but also on the future roadmap. In this paper, we take you through the differentiation between an on-premise Virtual Desktop Infrastructure (VDI) and a Desktop as a Service (DaaS) solution and assist you with the planning and execution of your journey to Azure Virtual Desktop (formerly known as Windows Virtual Desktop). www.hexaware.com | © Hexaware Technologies.

VMWare Horizon have specific long time to set up and can be Although premise-based VDI does promise requirements for machine images, difficult to modify once established. operating systems and other software The scalability with a VDI deployment is to solve a lot of challenges presented by the required for different components of limited by the server resources. If you physical desktops, they do come with their desktop virtualization. VDI solutions also want to scale services up, the own set of challenges. Let’s delve a bit come with the responsibilities of requirement at your end is to first deeper into these challenges: managing the server, storage and purchase, install, and configure more networking. hardware. Huge Cost User Experience From purchasing the licences to A VDI solution, if physically the cost of upgrading servers and deployed near end users, provides data centers, VDI deployments require good user experience. But, if the data center significant capital expenses (CapEx) is too far away from the users, the user upfront. To this, the operating costs are experience gets impacted by high latency then added, which leads to higher and low bandwidth. Also, VDI solutions may expense for an overall on-premise VDI not be able to provide the OS or application solution. versions that users expect, which might lead to incompatibility and cause inconvenience to the end users. www.hexaware.com | © Hexaware Technologies.

These requirements were dictated by real-time system applications which are increasingly being implemented on asymmetric dual-core processors running different operating systems. A real time systems laboratory curriculum based on dual- core architectures has been presented in this forum in the past.2 It was designed for a senior elective course in real time systems at the University of Texas at Tyler that combines lectures along with an integrated lab.

The Hypervisor is the one which provides the complete virtualization environment which will intend to virtualize as much as hardware and systems which will include the CPUs, Memory, network interfaces and so on. Because of the virtualization technologies such as the KVM and others such as ESXi, there has been a significant decrease in the usage if the resources and decrease in the costs involved.

Both server virtualization and desktop virtualization are briefly presented, but desktop virtualization is discussed in more details. As the size of computer systems grows every day with new applications, and with new client and market requirements, it is obvious that something must be done to ease the administration and effectively secure data. Additionally, disaster recovery plans must be improved too. Virtualization has solved many of these requirements and has become more and more popular so that many companies decided to implement a virtual server, virtual storage or/and virtual desktops. The paper lists the reasons why to implement virtual desktops and servers and what are the main benefits of such implementations. Virtual environments the also have some downsides, which are presented, explained and compared to the advantages.

    PART I FOUNDATIONS COPYRIGHTED MATERIAL CHAPTER 1 INTRODUCTION TO CLOUD COMPUTING WILLIAM VOORSLUYS, JAMES BROBERG, and RAJKUMAR BUYYA 1.1 CLOUD COMPUTING IN A NUTSHELL When plugging an electric appliance into an outlet, we care neither how electric power is generated nor how it gets to that outlet. This is possible because electricity is virtualized; that is, it is readily available from a wall socket that hides power generation stations and a huge distribution grid. When extended to information technologies, this concept means delivering useful functions while hiding how their internals work. Computing itself, to be considered fully virtualized, must allow computers to be built from distributed components such as processing, storage, data, and software resources [1]. Technologies such as cluster, grid, and now, cloud computing, have all aimed at allowing access to large amounts of computing power in a fully virtualized manner, by aggregating resources and offering a single system view. In addition, an important aim of these technologies has been delivering computing as a utility. Utility computing describes a business model for on-demand delivery of computing power; consumers pay providers based on usage (“pay- as-you-go”), similar to the way in which we currently obtain services from traditional public utility services such as water, electricity, gas, and telephony. Cloud computing has been coined as an umbrella term to describe a category of sophisticated on-demand computing services initially offered by commercial providers, such as Amazon, Google, and Microsoft. It denotes a model on which a computing infrastructure is viewed as a “cloud,” from which businesses and individuals access applications from anywhere in the world on demand [2].
