Virtual desktop infrastructure (VDI) also known as server-based computing, is where a desktop operating system within a virtual machine is run on a central server.
Desktop as a Service (DaaS) is a cloud service where a cloud service provider in a data-centre rather than in a central server hosts the back end of the virtual desktop in your business.
With a lot of similarities and differences between VDI and DaaS, it is often difficult to see which would most benefit your business. Hopefully this article will help understand the advantages and disadvantages of both.
DaaS removes the need for in-house IT
The main difference between VDI and DaaS is that DaaS is cloud hosted, so your business does not manage or maintain the server. Instead a hosted desktop service takes control, and in the event of any updates, network issues or other maintenance requirements, you don’t have to do anything!
DaaS is cost effective
With DaaS, you pay for what you use. So, if your company needs 250GB of shared storage, and you have 20 employees you will have the exact amount of shared and personal storage you require. If you gain or lose employees, then the amount of license you have can be altered.
In comparison, with VDI, you own the server, which involves a large up-front cost. Additional support normally comes from an in-house IT member of staff or an IT support company, again which adds expenditure to the system.
Connectivity is questioned with DaaS
Many people believe that connectivity is an issue with DaaS, as it is an internet hosted solution. However, it can be a bigger problem with VDI. With DaaS, while it depends on you having an internet connection, the chances are you have access to either WiFi or 3G. However with VDI, if the internet in the building goes down, then the server does not connect to computers, and data is inaccessible. At a data-centre, all tier1 internet providers have cables running, so if one internet provider goes down, it is re-routed to a second provider to ensure a smooth connection.
Data Security with DaaS and VDi
Because DaaS is not hosted under your companies roof, there are concerns over data control. However, companies often use an old version of firewall on their internal server, which can be at risk of hackers or viruses. In contrast, data centres ensure that all data is protected by the most up-to-date firewall and security software.
