DaaS vs. IaaS for Desktops
Grazed from Virtualization Review. Author: Elias Khnaser.
Let’s continue the cloud conversaton that I brought up in last week’s blog, but this time on another topic that has garnered steam in the last few weeks among my customers: Desktop as a Service. Customers are now asking, why DaaS instead of VDI? I don’t want to turn this blog into a comparison between them and this fight has been discussed to death in other forums. Still, I’d like to highlight a few things that DaaS needs before it is a viable alternative to VDI. The biggest hurdle is Microsoft licensing. At the moment, the company doesn’t have a Service Provider License Agreement for its desktop operating system products and that means customers have to provide their own Microsoft licensing to their DaaS provider. I have a problem with that — without one, it gets very complicated, even more so than VDI Besides, it then is no longer provided in an "as a service" model.
Here’s another hurdle: DaaS providers are delivering Windows Remote Desktop Session Host desktops and accessorizing them with a Windows 7 theme, and that presents its own set of challenges with apps and other considerations. There is also the concern with data ownership and compliance. Most important, DaaS would be limited to SaaS applications or Windows applications that are self-sufficient, meaning they don’t need access to the corporate data or back-end databases. These are just very quick nuggets of some show-stoppers that I see at the moment…



Dell announced on Monday it will acquire Enstratius, an enterprise cloud management software firm, for an undisclosed amount. Founded in 2008, Enstratius offers cloud management services to hybrid and single-cloud customers as a software-as-a-service (SaaS) offering that sits either as a hosted service or within the network. By embracing a "cloud agnostic" platform, the technology works with both Dell and non-Dell customers, including OpenStack, Microsoft’s Azure, Amazon Web Services, VMware and Rackspace, just to name a few.
