Presentation Virtualization

Presentation Virtualization is an application delivery method that delivers users desktops and applications from a shared server, AKA server based computing. This method of delivering applications to users focuses upon running an instance of each Windows desktop operating system application i.e., Word, Excel, PowerPoint and Office for each user on a shared instance of a Windows Server operating system. (Read More)

The most popular product in this category is Citrix XenApp and its predecessors which include Citrix Presentation Server, and Citrix MetaFrame. In the 6.0 releases of its products, Citrix bundled XenApp into XenDesktop. In the 7.0 releases of its products, XenApp has been made available separately again. Microsoft also has a product in this category – Microsoft Remote Desktop Services, but this offering is mostly used in smaller implementations that do not require the enterprise class features that Citrix offers.

If Citrix is on a buying spree – should its next purchase be Virtual Computer?

Like a new college student, fresh from the flush of new found freedom to expand their horizons, Citrix appear to have had a case of the munchies. First Citrix’s portfolio was extended with the acquitisition of Kaviza. More recently, the purchase of RingCube. The desktop virtualisation techhnologies acquired will help strengthen Citrix’s virtualised desktop offering. VDI-in-a-box offering simplicity of deployment, providing options for the SMB and MSP spaces; and vDesk providing a layering functionality giving greater VDI scalability with an improved personalisation offering.

While there has been little innovation in the XenApp line since v6.0 to date, the proposed next release (XA 6.5, “Iron Cove”) is slated to offer improved administration and service management – but perhaps importantly include a more “Windows 7” feel for Presentation Virtualisation (RDS/TS) sessions.  Continue reading If Citrix is on a buying spree – should its next purchase be Virtual Computer?

Performance Management for Desktop Virtualization (VDI) and Presentation Virtualization (SBC)

CIOs see selecting the right technology provider for their desktop virtualization strategy as a “significant risk”, according to research firm Ovum.  Ovum found that simplifying the management of desktops to reduce costs and increasing business agility were the top two reasons for implementing desktop virtualization, however,  an often overlooked aspect is the need to shift thinking from a device-centric perspective to a user-centric one.

Apple to put VDI and Terminal Services to the Lions and hail client hypervisors?

Apple have released their latest OS version. There are over 200 new features including autosaves, versioning, multi-touch gestures, access to the Mac App Store and, multi-user screen sharing. But Apple have not only changed the look and feel of the new, and significantly cheaper OS, they have changed their license terms as well.

One is the inclusion of clause to allow you to run multiple instances of the OS on your own device. A similar clause to one in Microsoft’s Windows 7 and a license feature that would sit well with a client-side hypervisor solution – giving administrators centralised control and management of end-devices.  In the Panther and Leopard releases, Apple added features to allow fast user switching and screen sharing: possible precursors to a native Terminal Services function. For some enterprises, a virtual Mac OS X environment would be a desktop Nirvana: giving access to Mac-only applications on-demand without having to supply Mac hardware on a one-to-one basis.

Does the multi-user screen sharing function provide a native Mac Terminal Services solution? Will Lion allow you to virtualize the Mac OS to take pride of place in your desktop delivery strategy and finally maul Microsoft’s Windows dominance?

Citrix announces IaaS Project Olympus built on OpenStack

I like OpenStack (the Open Source IaaS Cloud Platform intiative), partly because of the model of open innovation and permissive licencing (which reminds me of my time at Eclipse) and partly because even within the existing governance model (which I have criticised) there is the opportunity for different agendas to surface and to drive the project in different directions and this diversity makes an analyst’s life more interesting.

One of the most intriguing names that has hitherto been at the periphery of the OpenStack initiative is Citrix. Up until last week, Citrix’s contribution was to ensure OpenStack ran on XenServer, something which I’m sure Citrix cares about, but perhaps wasn’t top of the list of requirements for the rest of the world. However, this week at it’s Synergy event, Citrix made some more sigificant announcements about Project Olympus, through which it aims to provide (in collaboration with Dell and Rackspace) a route to commercial exploitation of the OpenStack codebase.

Citrix License RES Reverse Seamless Windows

RES Software confirmed today that it is has signed an agreement with Citrix to license RES’ reverse seamless Windows technology.

Citrix confirmed that while it has a license to use RES Virtual Desktop Extender (VDX) it does not intend to integrate RES’ VDX solution into it’s own products. Instead it has taken out the license to allow it to implement its own reverse seamless solution without running afoul of the patent that RES holds on reverse seamless Windows.
