within the land of Citrix, what was as soon as called "Presentation Server" is now "XenApp." Of direction, there's more to...
this anecdote than a cognomen alternate -- Presentation Server 4.0 became replaced by XenApp 4.5, which is now being replaced through XenApp 5.0 characteristic Pack 2. The identify alternate simplest provides to the confusion. Citrix is making an attempt to propel bewilderment apart and tout the merits provided by using XenApp 5.0 characteristic Pack 2, aiming to faucet in to a potentially massive upgrade market. however many techniques administrators had been sluggish to improve, claiming that the upgrade technique is fraught with complexities, poor back and risky documentation.
With that in mind, why would you want to upgrade from XenApp 4.5 to XenApp 5.0? in accordance with Citrix, there are a few factors including:
The help dispute turns into greater compelling when relocating from Presentation Server four.0 to XenApp 5.0. not only attain you find the above improvements, however which you can additionally garner privilege here enhancements:
Most systems administrators running prior types of XenApp or Presentation Server will find whatever thing of value within the stream to XenApp 5, and they're going to wish to circulation to Citrix's latest application virtualization product.
adding gasoline to the fireplace is the advent of windows 7, which might straight away develop into the de facto accustomed laptop working outfit for many corporations which are changing PCs. That should pressure the requisite for XenApp 5 on two fronts: easing the deployment of functions to fresh PCs and supporting the brand fresh elements of windows 7.
The advancements in XenApp 5 combined with the requirements of windows 7 will shift the "Is upgrading price it?" query over to "What attain I deserve to attain to upgrade?" because of this, admins are going to requisite to confront the complicated and difficult upgrade process.
but through following some average-experience rules, blended with a shrimp abilities about Citrix items, most systems directors should quiet exist in a position to address the help and forestall the regular "gotchas."
The planFirst off, engineer an help plan. That plot will involve a listing of the server hardware, the functions which are virtualized, the implementation and design of any present XenApp/Presentation Server configuration, the laptop working methods in use, and the server operating systems in location. That suggestions will back administrators to select an help strategy. Most upgraders will select considered one of three paths: an in-area migration, an upgrade or a clean installation.
those looking to installation fresh servers or appreciably help hardware as section of their XenApp deployment will requisite to pursue a pellucid installation, in reality ranging from scratch. youngsters a clean install nonetheless requires extensive planning, Citrix offers extensive documentation and support. enhancements, in spite of this, involve installation a newer version of a characteristic or unencumber merchandise over an present version and exist essentially the most not effortless course to follow. Even Citrix's documentation states that "the condition possible, migrations are preferable."
whereas pellucid installs may exist probably the most straightforward components of going to XenApp 5.0 duty Pack 2, a migration may well exist the most desirable technique to creep from Presentation Server four.5. Migrations blend one of the crucial simplicity of a clean install with the advantages of an improve. however an in-region migration quiet poses several chores and complexity.
So why ebb throughout the trouble?
The reply is tremendously fundamental: An in-region migration preserves the present digital applications and simplifies licensing and application deployment to computing device PCs in the business. methods administrators who determine to behavior in-area migrations will requisite to set together for a number of hours of downtime for their virtualized applications.
Naturally, one of the first steps earlier than attempting a migration is to absolutely lower back up the present Presentation Server/XenApp techniques and then investigate these backups to recuperate instantly if a migration fails. a further crucial project is to evaluation the fresh terminology used with XenApp as a result of most of the older phrases associated with Presentation Server had been renamed. not figuring out the brand fresh terminology and the route it pertains to latest facets can result in confusion All over a migration.
Citrix offers a number of instance configurations and a preconfigured XenApp contrast ambiance that upgraders can access to verify-pressure the product's fresh aspects and capabilities. stronger yet, admins may quiet trust doing a number of "look at various" migrations in a lab ambiance to forestall unforeseen considerations.
The migration system is accomplished in a few steps, which Citrix defines as:
every of those steps requires administrative intervention, and not All are driven by means of wizard-category installers. during the past, many americans had been requisite of Citrix for not publishing in-depth help documentation, however with XenApp 5, that has modified. Citrix offers several pieces of assist documentation, which ebb into further detail for specific migration cases. although, that documentation can exist a shrimp problematic to locate on the company's web site. here are some direct hyperlinks to those bits of suggestions:
With some watchful planning, experimentation and due diligence, upgrading to Citrix's latest and premiere virtualization tools should no longer present any foremost difficulties -- as long as programs administrators are prepared.

I beget a confession to make: When it comes to Citrix’s XenServer/Presentation Server/MetaFrame/WinFrame product line, I’ve always been biased. I simply esteem it. I recollect giving people JDE software in a midsize manufacturing company (that has since been swallowed by a big imperial juggernaut.) When I was a server admin there, I had only to deploy the Citrix client and some configs and the desktop admins loved me for it. At my prior company, I recollect going desktop to desktop putting nasty, frequently-updated-due-to-crappy-design applications on hundreds of clients’ desktops. Thanks to Citrix, I was the office hero because staff could toil at home when they needed to.
Then I discovered VMware and fell in esteem All over again. Now, I could deploy moneyed desktops without granting server access to the desktop. I could consolidate hundreds of servers, roll out emergency desktops in half the time, deploy servers from cloned templates with ease and backup entire systems without any agents. The only problem was that I never had Citrix evade well on ESX 2 and 2.5, even though I was being told that Citrix and VMware ebb together affection PB and J. If I were to anthropomorphize the gross thing (and I will) I’d exclaim the two were envious of each other and vied for my esteem and affection.
Putting Citrix on VMwareI had been advising people against using Citrix and VMware together; but should one insist, I beget always recommended that they attain some grave testing first. Then one day I broke down: After having read the VMware Performance Study and a noteworthy VMTN post, I figured it was about time I did my own testing. And affection the aforementioned references, I got noteworthy results.
I officially rolled out Citrix Presentation Server on VI3.5 and the performance has been stellar. I don’t beget a lot of users on the Presentation Servers, but I evade them alongside other production servers hosting the server side of some medical applications (billing applications, etc.), effectively putting the client and server on the selfsame hosts. I’ve done this for my own office and for a yoke of clients now. You could exclaim that I am officially backpedaling now and embracing Citrix on VMware.
Here are my suggestions if you determine to try this for yourself:
Disaster recovery services (DRS) – exercise anti-affinity rules to hold your Citrix servers from bunching up together if you allow automatic allocations. While it’s unlikely that a big farm will wind up with All of its Citrix eggs in a few baskets and then lose All of those baskets, it’s a possibility that should exist planned for.
Storage – exercise the fastest storage you can use. Citrix directly affects the user undergo and shouldn’t exist skimped on. late Citrix equals unhappy masses, which equals poor perception of IT, which equals job troubles for you. If you beget multiple storage area networks (SANs) to connect to, or even multiple logical unit numbers (LUNs) on the selfsame SAN in different RAID groups, sunder out the virtual machine disk files across your storage infrastructure to minimize the amount of disk I/O that Citrix boxes can generate (this is a fine thing to attain in any Citrix environment, not just a virtualized one.) Granted, I’m talking out of the side of my head here, since I evade one of my Citrix farms on an iSCSI SAN, and it performs very well, but scalability may exist an issue I don’t beget to address to the selfsame degree as the largest enterprises.
Benefits of a Citrix on VMware systemThe net result I’m seeing is an middling of 18-20 users on each Citrix box before performance starts to tank. I was getting the selfsame performance on my physical boxes. I don’t requisite to schedule a reboot as frequently due to remembrance leaks (though they also redid the basis Win2K3 install for R2, so I can’t definitely point to virtualization as benefactor here), and when I attain reboot, the reboot time is, affection any virtual system, much faster than a hardware reboot.
Since I now can set my Citrix disk on the SAN, I can attain block-level backup of data stored on Citrix servers (which, as any Citrix admin can Tell you, happens no matter what you attain since users always find a way.) Having templates makes it effortless to roll out fresh Citrix boxes as well, especially since PS4.5 makes adding a fresh Citrix box to your farm a breeze. Then there’s my favorite: snapshots. I’d capture a lower user/server ration if I had to just to beget this feature. Luckily, I don’t beget to. I can capture snapshots just before and after every fresh application is installed for publishing; before and after every app is patched; before and after updating Windows; and before and after updating Citrix. Being able to roll back with such ease is what makes me truly, deeply joyous with Citrix on VMware.
So, selfsame user/server ratio, shorter downtime periods, quicker deployment and snapshots: I call this a win-win.
VIRTUALIZATIONNew desktop virtualization solutions can crop costs and bolster security
Maintaining employees' computers is one of the information technology department’s most thankless responsibilities. The desktop and laptop PCs that are fixtures of today’s workplace devour up IT staff time and a fine slice of the department’s capital budget. But usually, the IT department hears from users only when the devices are broken or tied to a security breach.
Desktop virtualization technologies probably won't accomplish users any more appreciative, but by centralizing desktop administration tasks in the data center they can lighten the load on the IT department while enhancing security. Estimates on the potential cost savings vary widely because the upfront costs for buying virtualization systems or upgrading existing infrastructure such as networks to back it shift depending on the would-be implementer’s situation. But analysts attain disagree that overall costs will further down in the long run, sometimes significantly.
Part of that challenge is that agency leaders beget to sort through several virtualization options, and choosing the best one — or a combination — for each unique situation can exist difficult.
Desktop virtualization aims to simplify desktop computing in much the selfsame route as its better-known sibling, server virtualization, lets agencies crop stout in the data center by running multiple virtual machines on a single physical one. Fewer servers means less hardware and lower back costs.
Desktop virtualization doesn’t eliminate computers from users’ desks, but it does allow workers to find by with less expensive, stripped-down models or even older, re-purposed units. The technology transfers a lot of PCs' brains and data storage to central servers in the data center, where IT staff members can manage them more efficiently, including keeping them up-to-date with security patches.
Government has been broadly adopting server virtualization, which is now a fairly settled and develope technology. The desktop variety, in contrast, presents a more varied landscape. Indeed, buyers countenance multiple technical approaches to desktop virtualization. Those flavors, in turn, feature different levels of customer adoption and tender different potential benefits.
The stint for customers is to determine which desktop virtualization approach — or combination of methods — best suits their needs.
“A lot of people are wrestling with that these days,” said Joe Brown, president of Accelera Solutions, an IT solutions provider that specializes in virtualization and works in the government market.
Here’s a rundown on the main forms of desktop virtualization.
Option A: Presentation virtualization/application virtualization
How it works
Presentation virtualization lets users partake an application hosted on a central terminal server. Instead of having expensive, full-functioning PCs on their desks, users beget thin clients, which are stripped-down computers with no difficult drives. The servers ply the data storage and the bulk of the application processing action, reclaim for the user interface, which runs locally on the user’s desktop machine.
Microsoft’s Windows Terminal Services and Citrix Systems' Presentation Server — now rebranded as XenApp — are examples of the approach.
Such presentation solutions are simple to deploy as long as adequate network bandwidth is available, said Jim Smid, data center exercise manager at Apptis Technology Solutions, an integrator with many government customers.
Brown said Citrix’s technology, in particular, has proven an efficient solution for delivering a benchmark application to a big group of users who beget regular network access. He said this approach can cover the desktop application needs of 30 to 40 percent of a typical organization’s users.
In the past, presentation virtualization wasn't an option for users who don’t beget regular network access. But vendors beget added a fresh capability called application streaming or application virtualization that address this mobile population. Citrix’s XenApp, for example, can deliver a mobile version of applications to workers’ desktops while they are connected. They can then evade that application later even when there is no network connection.
VMware’s ThinApp and Microsoft’s App-V also tender application streaming.
Where it fits
Presentation virtualization and application virtualization play different roles in an organization.
Presentation virtualization sees the greatest exercise among stint workers who exercise a limited number of benchmark applications, such as in call centers, said Tom Simmons, area vice president at Citrix's Government Systems division. Another niche is presenting existing applications that are difficult to manage on the client side.
It is also a fine option for users who requisite benchmark applications that access large, centrally stored datasets, said Rhys Ziemer, a technology expert at Microsoft.
Meanwhile, application virtualization and streaming provide centrally controlled and distributed apps to users, whether they are in-office workers with constant network access or mobile workers with only occasional network access.
Industry executives identify presentation virtualization and application virtualization as the most common forms of the technology. They said the ability to centrally manage applications and meet security standards, such as the Federal Desktop Core Configuration, rank among the attractions in government.
FDCC, a mandate of the Office of Management and Budget, calls for agencies to introduce benchmark configurations of Windows XP and Vista PCs in an exertion to boost security.
Option B: Virtual desktop infrastructure (VDI)
How it works
VDI represents a newer development in desktop virtualization, and it is just now emerging among government agencies. The technology also falls under the hosted virtual desktop label. VDI Products involve Citrix's XenDesktop, Parallels’ VDI and VMware’s View.
Microsoft, meanwhile, provides a basic, manageable VDI infrastructure with its upcoming Windows Server 2008 R2, Rhys said. general availability is slated for later this year.
The hosted virtual desktop approach is an exertion to centralize user computing. Although a traditional PC houses the operating system, applications and data on a local difficult drive, a virtual desktop places those elements in the data center. Each user’s desktop is maintained as a virtual machine running on a central server. A server could potentially host thousands of such virtual desktops for an agency's user population.
A connection broker, which supports one or more remote viewing protocols, links the user to his or her virtual desktop. Virtualization software vendors tender connection brokers, and third-party brokers are available from companies such as Leostream and Quest Software.
An organization might pick to exercise a conventional PC — a thick client — to panoply the virtual desktop or opt for a smaller device, such as a thin client or even an older model PC.
Where it fits
VDI offers greater opportunities for customizing the user undergo compared with shared presentations of server-based applications.
Each virtual desktop residing in the back-end server infrastructure exists independently of All others. This isolation gives All users “their own personalized desktop,” said Raj Mallempati, group product manager for desktop solutions at VMware.
Accordingly, Brown said he recommends hosted virtual desktops for users who requisite personalization capabilities that a shared platform wouldn’t provide. He added that virtual desktops also avoid some application compatibility issues create in shared-computer environments.
VDI might also prove to exist a appropriate for organizations that hunt to maintain traditional desktop capabilities such as bi-directional audio/video and streaming video that are difficult or impossible in a shared presentation profile of virtualization.
“As much as possible, they completely replicate the physical environment by doing things affection bi-directional audio and video,” said Paul Garver, vice president of Quest Software's public sector division.
For the most part, VDI has surfaced as proof-of-concept deployments in government. But larger deployments beget begun to emerge.
At the U.S. Patent and Trademark Office, 2,110 production employees — including trademark attorneys and Board of Patent Appeals judges — exercise a virtual machine for desktop computing, an agency spokeswoman said. USPTO’s desktop virtualization is built on VMware’s server and desktop products.
Elsewhere, Pike County Schools in eastern Kentucky has adopted a virtual desktop approach using IBM’s desktop cloud service. IBM hosts the VMware-based virtualized infrastructure, which spans 1,500 client machines.
Students access virtual desktops from an array of computer devices, including many older desktop models. “We can bring them back to life — benevolent of affection Frankenstein,” said Marrita Horne, Pike County Schools' technology director.
District officials hope to add 2,000 more computers to the virtual service, including older machines that otherwise would beget been scrapped. Horne also preeminent improved security as another edge for the virtual desktop environment.
Option C: Virtual desktop/client-side hypervisor
How it works
In this wrinkle, the virtualization software operates only on a user's PC. This technology lets users operate virtual machines on their own devices as opposed to relying on a server to attain the virtualization chores.
VMware set the market in motion in 1999, with the debut of VMware Workstation — the company’s first product. Workstation allows a PC to evade multiple operating systems. Products in the Workstation mold are called kind 2 hypervisors because they evade within an operating system. kind 1 hypervisors, typical of server virtualization, evade directly on hardware.
However, some vendors are pushing kind 1 hypervisors to the desktop. Citrix’s Project Independence, in which it collaborates with Intel, marks one exertion to develop a client-side hypervisor.
Where it fits
In recent years, products that let Apple Mac users evade Windows or Linux beget been a well-liked exercise of desktop virtualization. Parallels’ Desktop for Mac and VMware’s Fusion topple into that category.
The government has provided a even source of users who want the ability to evade Mac and Windows applications side by side. Bill Portin, vice president of sales and operations at Parallels, listed NASA, the National Institutes of Health and the Energy Department's national laboratories among the company's customers.
Aileen Black, vice president of VMware’s public-sector division, said Fusion is taking off in the Army, which recently purchased 7,500 Macs. The Defense Department and intelligence agencies beget also requested it, she said.
