The Nivio experience was different than the other DaaS providers, following a model that's very retail-like on the surface, but had some depth of configuration. Based on Citrix XenServer, Nivio used a commodity-based session model for its desktop services. You can get persistent or non-persistent sessions, rent or license apps, and use the session-spawned "nDrive" to save and collaborate pre-loaded or production data among groups of users. The feel of Nivio is more ad hoc (and for less formal deployments) and spontaneous. There's an "nApps" store, an organizational URL yourorg.niv.io, and the nDrive. The "n" theme was catchy; some will find it gets old to them.
Nivio doesn't provision standard Windows 7 sessions. Instead, we got terminal-server like sessions running on Windows 2008R2 Server. Nivio uses Ericom AccessNow 2 graphics acceleration server for HTML5 graphics speed enhancement, a product we saw in a prior edition (and earlier stages) in our coverage of VDI server infrastructure.
Nivio eshews typical Citrix XenServer client infrastructure, and used Adobe Flash-based browser access or HTML5 browser access. Flash adds compatibility but at the potential sacrifice of non-Flash client-types -- but it's possible to use an HTML5-compatible browser (apparently IE9 is incompatible with Nivio's sofware) to logon to a virtual Nivio session. We ran into some access problems with Firefox 11, but Nivio proved to us that there's a bug in Firefox 11 in which mixed SSL-encrypted and non-encrypted data aren't correctly handled from their perspective; perhaps it's fixed by the time your read this, but we found the portions of the session used were encrypted correctly, just not reported by Firefox as encrypted.
The sessions are hosted in turn on a Windows 2008 R2 server, terminal server-style. The sessions were highly policy controlled, but contained a full payload of standard-issue Microsoft Office apps. If you use Windows, you're in Windows and no retraining ought to be required to make use of the Citrix Windows session UI.
The Nivio nApp offerings were divided into several categories, including free and rentable. While the list wasn't very long, we found its inclusion interesting in the face of other application stores like iTunes or Google Marketplace. If you want to use free office applications, several choices are available, as well as familiar Microsoft Office at a rental price.
