The desktop virtualizationeither Desktop as a Service (DaaS)is a service hosted in the cloud that allows a service provider to provide companies with access to a virtual desktop infrastructure (VDI) from anywhere over the Internet, under license and on a per user subscription basis. It is a modality that offers many advantages, especially to small and medium-sized enterprises (SMEs).
With DaaS, desktop operating systems may be able to run within Virtual machines on servers that are housed in the data center of a cloud provider. All the necessary supporting infrastructure, including network and storage resources, is also hosted in the cloud.
As with on-premises VDI, a DaaS provider is responsible for issuing virtual desktops over a network to a customer’s endpoint devices, where users can access them via client software or a web browser. .
How does desktop as a service work?
DaaS is characterized by having a multi-tenant structurewith which organizations acquire the service through a model of subscriptionwhich is generally based on the number of virtual desktop instances used per month.
In the desktop-as-a-service delivery model, back-end responsibilities for data storage, backup, security, and updates are managed by the IT and cloud provider. While it is true that the provider bears all the costs and maintenance of the back-end infrastructure, generally it is the customers themselves who manage their own virtual desktop images, applications and security, unless those desktop management services are part of the subscription.
Typically, the personal data of an end user are copied to and from your virtual desktop during logon and logoutplus desktop access is independent of the specific device, location, and network.
Advantages of DaaS
The main advantage offered by DaaS, like similar services, is that of provide access to virtual desktops from anywhere in the world just by having an Internet connection. In that sense, for example, any company or organization could provide remote employees with a user experience that largely emulates that of users working on site.
Another advantage of DaaS has to do with the fact that cloud service providers generally make it easy for users to scale virtual desktop deployments. Taking into account that virtual desktops are hosted on cloud infrastructure, organizations they don’t need to worry about purchasing and deploying the additional physical hardware required to scale an on-premises VDI infrastructure.
Also allows users to work from any device they select. For example, if a user decides to work from a PC, Mac, or mobile device, you will be able to access DaaS as long as it has the necessary screen resolution and remote desktop client software. The user’s desktop environment is identical, regardless of the type of device they are using.
One of the biggest benefits is the ability to reduce costs and save energy, since devices running DaaS need much less processing power than a traditional laptop or desktop.
Similarly, with DaaS the security risks are much lower, since the data is stored in the data center and not on the devices. In other words, in the event that a user is the victim of the theft of a laptop or mobile device, all they have to do is disconnect it from the service.
Finally, both updates and security patches are also easier to install in a DaaS environment, since all desktops have the particularity of being updated from a remote location and simultaneously.
Major DaaS Providers
Today, there are numerous desktop-as-a-service providers. Some of the best known in the world are Y
Amazon and Microsoft are also on their way to becoming major DaaS players thanks to their cloud workspaces. (AWS), and of Windows Virtual Desktoprespectively.
