Key Differences Between Virtual Desktop Infrastructure (VDI) and Desktop-as-a-Service

A Contributed Article by Deney Dentel, CEO, Nordisk Systems Inc.

In the case of using a virtual desktop infrastructure (VDI), many diverse options open up for the IT administrators that operate them. Often, many wonder what is the difference between virtual desktop infrastructure, protocols that operate on the remote display basis, and all other alternatives that are in use. With virtual desktops, the main characteristic is the fact that they are hosted in a data center. But, as the options for cloud hosting grows ever more accessible and affordable, there is also the option of hosting them in a cloud system.

This variation of VDI infrastructure is called desktop as a service (DaaS), and with it users can outsource their desktops to providers of cloud services. In this case, both virtual desktop infrastructure and desktop as a service share a lot of the benefits, including desktop management, substantially less hardware, more flexibility and even more mobility. At the same time, this option presents its own issues which need to be addressed, including licensing, control of data and security. Here are the main differences between these IT infrastructural variations that can help any organization decide what the exact thing they need is.

DaaS takes Infrastructure out of IT's hands:

Firstly, the key difference between a DaaS and VDI is the fact that with desktops that are hosted on a cloud, the IT sector can stop worrying about the technology and devices that are running to support them. This role is taken on by the providers, which also cover issues with network and load balance. But, the same department still needs to manage virtual desktops, clients, and application and run the remote logging protocol.

Cloud-based apps affect VDI adoption:

Cloud providers and their services in the DaaS area are interesting for any business because they lower the cost of infrastructure when they are compared to a virtual desktop infrastructure. They also make a lot of sense for the application that operate on the web. In spite of this, many IT sectors prefer central management, security and control that virtual desktop infrastructure provides.

Cloud-hosted desktops can cut costs, complexity:

For all those who do not desire to control a lot of infrastructure at the back-end of a network, the desktop as a service providers are a great choice, even more they do not have to house any virtual desktop infrastructure experts. Desktops on a cloud lower cost of PC management and have no need for a firewall, which makes them faster. But, they still have some latency thanks to remote access that is always present with them.

Weighing DaaS vs. VDI: What's right for you?

Thanks to the fact that desktops hosted on a cloud are not connected to a data center's servers, they can be moved freely, patched, upgraded or fully restored if they fail for any reason. Also, desktop as a service has a lot more flexibility than any virtual desktop infrastructure because it allows for new users on any device that is brought into the network. The same is true for diminishing concerns about the state of the network, mainly because desktops hosted on a cloud are connected through connections that are private. These only later enter the designated corporate environment.
