The key differences between VDI, DaaS and Hosted Desktops?
As a business owner, we appreciate that selecting a cloud solution that is both cost effective and flexible can be an overwhelming task. If you are in the process of considering the best cloud solution, filtering through the vast assortments of technologies available you need to know that these technologies are certainly not the same.
Hosted desktop works just like a normal PC desktop except the applications, user profiles and data and stored on a Windows Server operating system. Access to the hosted desktop is available through any internet connection with any internet enabled device. The “Hosted” concept means they are managed by a cloud provider, this removes the need for any local back end infrastructure for the business. Consequently, this reduces the upfront costs of providing the infrastructure of a data centre for sharing applications and data. These desktops generally use Microsoft Remote Desktop Services to present a Window desktop to the user and will look and feel very similar to a VDI desktop. The only difference for the user is that they are running on Windows Server rather than Windows 10. Although, it is worth noting they run exactly the same way, just on a different operating system.
Virtual computing is ingrained within all technologies we are comparing. Virtual desktop refers to a computer operating system that does not run directly on the endpoint hardware from which a user accesses it. The system runs on a 1 to 1 (user to operating system) basis from a central server or server farm. Virtual desktops enable users to logon to any computer and connect to their unique desktop allowing for true secure isolation. The desktops run like any physical PC and are compatible on systems such as Windows 7, 8 or 10. As a result, deployment of new desktops is usually very quick and local hardware can be very basic to the degree of thin client terminals.
Hosted applications allow users to execute and operate a software application entirely from the cloud on a recurring subscription. The hosted application removes the desktop label of hosted desktop, all the user sees are icons for the applications they want to run. When the applications starts it feels no different than if it was running locally on the PC. Accessing applications globally from a web portal, provides the same functionality as locally installed software. Hosted applications have the additional support benefits of hosted infrastructure such as Hosted SQL Servers, fast network storage and web servers.
Desktop as a Service
DaaS is an aspect of VDI in which the VDI is outsourced and handled by a third party. DaaS is frequently delivered as a cloud service typically associated with Hosted Desktops.
