The Virtualization Practice

Tag Archive for Quest

Whether you use replication as a means of disaster avoidance or disaster recovery, replication of your virtual environment between hot sites has always been a win. With current technology it is even possible to replicate to a replication receiver cloud which could provide a measure of business continuity as well. So who are the players and who provides what service, and how do they do it?

XenApp 6.5 is Citrix’s latest offering of their renowned Presentation Virtualisation (PV) service. Citrix are not alone in updating their feature set. Earlier in 2011 Microsoft introduced SP1 for 2008 enhancing the OS for the core Remote Desktop Services’ (RDS) session virtualization service, Ericom released PowerTerm WebConnect 5.7.1, ProPalms updated TSE to 6.5 and Quest announced vWorkspace 7.2 MR1.

Virtual Computer have redefined virtual desktops delivery with their latest release, NxTop 4. In NxTop4 Virtual Computer have aimed to further improve their client-side hypervisor desktop management solution and to better harness the power of end-point PCs for local execution rather than requiring major investments in virtual machine server farms.

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.

VMware view to release RTO profile solution. Is this lagging behind Citrix who have bought Ringcube? View now has profile management – but that isn’t user virtualisation. Does VDI need User Virtualization, or does User Virtualization need VDI? User Virtualization has the capacity to extend across desktop delivery boundaries because the user workspace, their applications and data are no longer bound to the desktop OS. Solutions available from vendors such as AppSense, UniDesk and RES. To deliver virtual desktops for the enterprise, it is not simply a case of managing profile load time better: many users need greater customisation than a shared desktop can deliver. In an enterprise environment VDI is not the only method of delivering desktops. A complete user virtualization solution needs to be able to accommodate, not only centralised hosted desktops, but off-line use as well and standard desktops.

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.

VMware View users along with Citirix XenDesktop and Quest vWorkspace have an iPad client for their respective solutions. Personal device use may seem appealing in reducing the demands on IT support – but to fully comply with the license agreements can incur additional license charges, and those charges are difficult to manage. Despite the advertising blurb attached to the free clients, the headaches for finance and IT are not over yet.

User Virtualization makes your user’s information manageable and portable. With User Virtualization the components of a desktop relating to the user are decoupled from the operating system and applications. Goldman Sachs investment is not to gain market share per se, but to allow AppSense to rapidly expand to meet the demand that their product has generated and helps drive a rapidly expanding desktop virtualization and management market.
