Virtual desktops as a service (DaaS) - a solution for cloud computing, in which the service provider provides the end users via the Internet virtual desktops with licensing for the number of users on a subscription basis.
The service provider manages the back-end for small businesses that find it too expensive or resource-intensive to build their own virtual desktop infrastructure . Management usually covers maintenance, backups, upgrades, and data storage. The security of virtual desktops and the applications used can be managed by both cloud providers and users. Within the DaaS model, you can use two types of virtual desktops: stateful and stateless.
Stateful virtual workstation . Users have the ability to customize and save the workplace so that its appearance remains the same every time a user logs on to the system. Stateful virtual desktops require more storage, increasing costs.Stateless virtual desktops are just a way to access shared cloud services. Each time the user logs off, the settings are erased.Cloud service providers give customers a choice of two options, giving employees with specific tasks stateful access to virtual desktops and temporary or non-permanent employees access to stateless virtual desktops.

With DaaS, deployment and retirement of virtual desktops for active end users is much faster and cheaper.
Accelerated deployment and retirement of virtual desktops for active end users . The virtual workstation is already configured, it only needs to be connected to a new device. DaaS can help save a lot of time and money for organizations that have seasonal fluctuations in demand or headcount fluctuations.Reduced downtime in providing IT support . Using the DaaS model, companies provide remote IT support to employees, reducing downtime.Reduced costs . DaaS devices require much less computing power than traditional desktops or laptops, and are therefore less expensive and consume less power.Increased flexibility to support a variety of devices . The DaaS model works on different OS and different types of devices. This is very convenient for users who prefer to work in the office on their personal devices. In addition, the cloud provider is responsible for all issues related to supporting virtual desktops on these devices.Enhanced security . Security risks are significantly reduced because the DaaS model stores data in the data center. If your laptop or mobile device is stolen, you can simply disconnect it from service. Since there will be no data on the stolen device, the risk of an attacker accessing confidential information will be minimal. In a DaaS environment, it is easier to install patches and security updates because all virtual desktops can be updated at the same time from a remote location.
How DaaS worksWith DaaS, the cloud provider hosts infrastructure, network resources, and storage in the cloud, and then streams the virtual desktop to the user's device. As a result, the user gains access to the data and applications of the virtual desktop using a web browser or other software. Organizations can purchase the required number of virtual desktops using the appropriate subscription model.
Because virtual desktop applications are streamed from a centralized server over the Internet, the use of graphical-intensive applications like DaaS has been a problem in the past. The situation has changed thanks to new technologies: now even such resource-intensive applications as computer-aided design systems work according to the DaaS model. If the load on a particular server becomes too high, IT administrators can move a running virtual machine from one physical server to another in seconds. This ensures that applications with graphics accelerators or GPUs run smoothly. The GPU-Accelerated Virtual Desktop as a Service (GPU-DaaS) model is in demand in any industry. where 3D modeling, high quality graphics, simulation or video production are required. This technology provides benefits to companies in the architecture, engineering and design, television and radio broadcasting industries.
