Desktop As a Service (DaaS) and VDI

Desktop as a Service (DaaS) – put simply, is nothing but VDI that you pay someone else to host for you.

A new term I learnt today, “Cloud bursting” your VDI, also called Hybrid Cloud. The idea here is that you combine traditional on-premises VDI with public cloud-based VDI (DaaS).

Ideally, you hook them together with the same front-end or the same framework so you can use your on-prem environment for most of your users but then “burst” to the cloud if you run out of capacity in your own VDI environment.

VDI

VDI is virtualization. And you know how to do virtualization. Since VDI is just Desktops running on hypervisors in your data centre and you already have a bunch of virtual servers today, VDI is just a logical extension of that.

That also means, VDI ensures consistent performance. because users’ desktops run on known server hardware with known performance characteristics.

Even if a user’s personal laptop is slow, the VDI desktop runs at full speed.
