Deep Dive Architecture Comparison of DaaS & VDI, Part 2

In part 1 of this blog series, I discussed the Horizon 7 architecture and a typical single-tenant deployment using Pods and Blocks. In this post I will discuss the Horizon DaaS platform architecture and how this offers massive scale for multiple tenants in a service provider environment.

Horizon DaaS Architecture

The fundamental difference with the Horizon DaaS platform is multi-tenancy architecture. There are no Connection or Security servers, but there are some commonalities. I mentioned Access Point previously, this was originally developed for Horizon Air, and is now a key component for both Horizon 7 and DaaS for remote access.

If you take a look at the diagram above you’ll see these key differences. Let’s start with the management appliances.

Deep Dive Architecture Comparison of DaaS & VDI, Part 1

In this two part blog series, I introduce the architecture behind Horizon DaaS and the recently announced Horizon 7. From a service provider point of view, the Horizon® family of products offers massive scale from both single-tenant deployments and multi-tenanted service offerings.

Many of you are very familiar with the term Virtual Desktop Infrastructure (VDI), but I don’t think the term does any justice to the evolution of the virtual desktop. VDI can have very different meanings depending on who you are talking to. Back in 2007 when VMware acquired Propero, which soon became VDM (then View and Horizon), VDI was very much about brokering virtual machines running a desktop OS to end-users using a remote display protocol. Almost a decade later, VMware Horizon is vastly different and it has matured into an enterprise desktop and application delivery platform for any device. Really… Horizon 7 is the ultimate supercar of VDI compared to what it was a decade ago.

I’ve read articles that compare VDI to DaaS but they all seem to skip this evolution of VDI and compare it to the traditional desktop broker of the past. DaaS on the other hand provides the platform of choice for service providers offering Desktops as a Service. DaaS was acquired in October 2013 (formerly Desktone). In fact I remember the day of the announcement because I was working on a large VMware Horizon deployment for a service provider at the time.

For this blog post I’d like to start our comparisons on the fundamental architecture of the Horizon DaaS platform to Horizon 7 which was announced in February 2016. This article is aimed at consultants and architects wishing to learn more about the DaaS platform.
