This option is much less customizable than the previous one. In a desktop as a service (DaaS) deployment model, you basically rent some cloud-based virtual machines from a service provider. Once the connection with a server is established, a user gets a desktop image transferred to him in real-time over the network and will be able to interact with that virtual image in the same way he’d operate a local computer. But in any case, with this deployment model, you’ll be the one to decide which apps, services, and tools will each of your users (or user groups) see on their virtual desktop. In this case, your service provider will host all the virtual machines on the servers in their data center and run all of them in parallel, if needed. You can either invest in your own server equipment and operate in-house VDI or turn to a service provider. It will be powered by a purpose-specific software (hypervisor). If you opt for the virtual desktop infrastructure (VDI) deployment model, you will get a specific virtual machine assigned to each of your users with an operating system and all required system resources, i.a., device drivers, memory, etc. What type of virtualization should you deploy to provide a virtual desktop infrastructure? Let’s take a look at the three most popular deployment models for desktop virtualization so you can decide which type of virtualization you should choose to provide the best virtual desktop experience for your users and team. Taking everything into account, desktop virtualization can separate a desktop environment from a given physical system while enabling several VMs to run on just one physical server. Next, the client software will send mouse and keyboard inputs to the VM to receive screen updates. Client Layer: It consists of a software solution installed on the user’s system.and users can remotely access applications from their systems via a remote display protocol. Application Layer: On top of the guest OS, applications are installed and run within the VM.It behaves as if it’s running on a physical device. It communicates with all the hardware resources that the hypervisor has allocated. Guest OS Layer: Every VM will have a guest operating system of its own, installed on the hypervisor.It communicates with the physical machine’s hardware resources in order to allocate memory, storage, network resources, and CPU to the VMs. Hypervisor Layer: This is a software layer used to create and manage VMs.On the other hand, the client or the user device interacts with the VM via a remote display protocol (RDP) transmitting keyboard input, mouse clicks, and screen updates. The process of virtualization involves many hardware and software abstraction layers, enabling the virtual machine to function like a real, physical computer having a CPU, storage, network resources, and RAM of its own. This way, applications and the operating system will be run on a virtual machine (VM) that’s hosted on that server, instead of running on the user’s device directly. In this case, whenever this user logs out, the virtual desktop won’t save any changes made to it during the session and, upon the next login, this user will get the new standard randomly assigned virtual machine.ĭesktop virtualization separates a physical machine’s desktop environment and hosts it on a cloud infrastructure or a server. Once he enters the login credentials and the connection is established, the remote desktop session starts with this user’s personal virtual machine or a standard VM assigned to him from a pool of virtual desktops at random. In most cases, a user connects to a virtual machine via the Internet using the remote desktop protocol (RDP). That software is a simulator that creates digital images called virtual machines (or VMs) that have operating systems, installed software applications ready to use, and also can hold all sorts of personalized settings and user data. Virtualization of desktops takes a specific purpose software tool called a hypervisor (or virtual machine monitor). The only condition is a stable Internet or network connection.įrom this article, you will get enough info on what is desktop virtualization, how desktop virtualization works, what benefits you can get from virtualized desktops, what are three types of desktop virtualization and how to choose the one which would be the best for your situation. The technology allows creating and storing multiple user workstations on a single host, residing in a data center or the cloud. By definition, desktop virtualization is a method of creating a workstation with all the apps and widgets your employees normally use so that they can access their desktop from any device or location.
