VDI — Virtual Desktop Infrastructure in a public cloud

Today, I’d like to talk a bit more about a VDI solution based on a public cloud. I’m sure that most of you have already heard the term VDI — Virtual Desktop Infrastructure. Solutions of this type have been on the market for quite some time. However, they were usually implemented based on a client’s own infrastructure (in his own Data Center). Before we get deeper into the topic, let’s explain the “classic” model of VDI.

Classic on site model of VDI

VDI main advantages

  • Providing a high mobility for users — they can use their virtual desktop from any place with access to the internet.
  • Allowing an app and a desktop to “follow” a user, e.g. a person starts work in the office, and finishes it at home.
  • Standardization of virtual workstations and installed applications.
  • Central configuration management — both OS and application in one place.
  • Data on virtual stations are processed on servers in a Data Center, and not on a user’s ones.
  • Station’s and data’s backup is performed centrally in a Data Center.
  • In case of a single host failure, a physical hosts cluster is provided by a high accessibility of virtual desktops.
  • A possibility to extend the lifetime of an IT equipment used for connecting to the VDI infrastructure. Such equipment is used “solely” to display an active session image.

VDI in a public cloud to the rescue

The undoubted advantage of Azure Virtual Desktop is an option to pay only for environments that were actually used — a Pay as You Go model — which helps save additional costs, especially in case of graphics stations used only a few days in a month.

Is VDI as a service worth your attention?

Here are some of the typical scenarios of using VDI in a cloud:

  • Remote work in a safe and centralized environment.
  • Access to older applications requiring specific configuration which is often impossible to achieve directly on users’ workstations.
  • Varied training or test environments.
  • Possibility to prepare virtual desktops in various geographical locations so they’re as near to the users as possible.
  • Option of using the most efficient and professional workstations only when it’s necessary. We pay for actual use of computing power.
