How the Desktop As a Service Options Comes Up?

Desktop-as-a-Service (DaaS) is an important innovation in cloud computing. It frees companies from the obligation to set up their own workstation for each employee. Since Corona in particular, the virtual desktop has been enjoying increasing popularity because it makes it easier to switch to the home office. Find out here what exactly Desktop as a Service MAC is, how the service works and what advantages it offers. For Apple also this is true.

What is Desktop-as-a-Service?

The easiest way to understand the concept of DaaS is to consider the following structure: A desktop application, for example Windows 10, runs on your notebook or PC. This is used to start programs, access files, and objects on the store a virtual desk and much more. You give commands to your desktop using your keyboard and mouse. conversely, the Mac Operating System desktop software shows you an image on your monitor.

Desktop-as-a-Service (DaaS) for Apple works the same way, except that the desktop application and the applications do not run on your computer, but in the cloud. On your computer you just open the web browser or a small client program that connects you to the server. Your desktop is on the remote server of a service provider. From there you receive the monitor image via the Internet via streaming and send your mouse and keyboard commands to the server in the same way.

In other words, the DaaS for Mac provider provides you with virtual desktop and virtual applications. “Virtual” refers to the fact that you feel as if the applications are running as usual on your computer: DaaS “simulates” your usual desktop. Desktop-as-a-Service makes it possible to access the desktop from many different devices: from laptops, desktop PCs, tablets or thin clients. In contrast to the conventional, locally installed desktop, no data is saved on your computer. both the applications and the files remain on the DaaS server for Mac Operating System.

How Desktop-as-a-Service (DaaS) works

DaaS offers two different flavors: persistent and non-persistent desktops.

Persistent desktops: Here you can adjust the desktop according to your wishes, just as you are used to from your computer. The next time you log in, you will find the desktop exactly as you left it.

Non-persistent desktops: In this variant, the virtual desktop is completely deleted when you log out. This saves storage capacity and can provide additional security in certain scenarios.

The DaaS provider, i.e. the cloud or managed Applikation services provider, takes care of the maintenance, updating, data backup and storage of the virtual desktop.

The Desktop as a Service is offered as a subscription solution, with different pricing models:

  • Monthly fixed rate (“flat fee”)
  • Hourly billing combined with a low monthly fee (on-demand pricing).
  • Own software licenses (“Bring Your Own License”, BYOL) or obtaining the licenses from the DaaS provider
  • Various levels of computer performance, for example number of CPU cores and size of main memory
  • Additional graphics processing power if required

There are many providers of DaaS. The currently best known are Amazon Web Services (Amazon WorkSpaces), Microsoft Azure (Windows Virtual Desktop), Citrix Virtual Apps and Desktops and VMware Horizon Cloud.

VDI vs. DaaS

VDI refers to the infrastructure for virtual desktops. The abbreviation stands for “Virtual Desktop Infrastructure”. With VDI, the company provides virtual desktops via its own data center. Your IT department takes care of the operation of the server and the network connection to the users. This can be a secure internet connection (private cloud) or a LAN. DaaS means the operation of a virtual desktop infrastructure by an external provider. In this case, the company does not have to operate its own server, but rather purchases the required Desktop as a Service.

Why use a fat client at all? There are multiple reasons for this:

  • Use of software that is seldom required and for which a separate license should not be installed on each computer, such as a special data analysis application for a time-limited project.
  • Temporarily required high computing power that exceeds the capacity of a thin client. Examples of this are a big data analysis, an elaborate video production or a complex 3D rendering.

Thin Client vs. Fat Client

Because the actual execution of the Cloud Desktop programs, data storage and computing power with Desktop as a Service take place entirely on the remote server, a computer with minimal equipment is sufficient. The technical term for this type of computer that is only set up for input and output is “thin client”. In contrast to this is the “fat client”: a full-fledged PC or laptop that is used to access the DaaS service. A fat client itself has a full-fledged desktop, storage capacity and locally installed application programs.
