Test Your Hardest VDI Use Cases First

Posted by Tom Rose on Dec 3, 2014

This blog is an excerpt from the Unidesk eBook Ten Quick Tips for Scaling VMware Horizon View.

Many pilots focus on simple VDI use cases with a minimal set of applications. This is why so many organizations say, “Everything seemed to work fine in our VDI pilot. But once we started putting virtual desktops into production, we hit a bunch of issues we never anticipated.”

Use your pilot to simulate what VMware Horizon View, Microsoft RDS, or Citrix XenDesktop will look like at scale. Target power users and knowledge workers who require diverse desktop configurations and graphics‐intensive applications. And, load your storage systems to make sure you have enough IOPS.

Persistent VDI or Non-Persistent VDI? Layering Ends the Debate

Posted by Tom Rose on Dec 1, 2014

Persistent desktops that sustain all user and IT customizations? Or non-persistent desktops that revert back to a pristine state after each use? There is still confusion and misinformation about which type of virtual desktop is better in VDI. Take the recent article "When should persistent VDI be used over non-persistent VDI?" on TechTarget for example.

The article claims "This is the No. 1 most debated, contested issue in the world of VDI." Maybe it was a few years ago. Not anymore. As the VDI user examples in this blog prove, both types of desktops are needed - often within the same organization. The decision of whether to implement persistent or non-persistent is now being based entirely on use case, not on the limitations of legacy desktop provisioning technology. What has ended the debate? Desktop layering innovation.

The History of VDI

Posted by Tom Rose on Nov 18, 2014

The history of VDI has been rocky at best. About this time every year, the running joke is that 20XX will be "The Year of VDI" (just look at past predictions from 2010, 2011, 2012, and 2013). However, in 2014 VDI has started to become mainstream and 2015 will be the year of VDI... I think. This post isn't about the future though. This post analyzes the 4 different "eras" of VDI, the challenges VDI had in each era, and why in the current era VDI will go mainstream.

Yes, One Gold Image in VDI is Possible

Posted by Tom Rose on Nov 17, 2014

This blog is an excerpt from the Unidesk eBook Ten Quick Tips for Scaling VMware Horizon View.

When VDI projects first start, there is typically one clean master of Microsoft Windows– the “golden image” – that is the foundation for all virtual desktops. As you rollout more desktops, however, you will find that they need different sets of applications. Building every application into a single Windows image will force you to license every app for every user, which most organizations cannot afford. Plus, you’ll have to update the master image every time you need to update one app.

At this point, most organizations start creating multiple Windows images with different combinations of apps for different departments and groups of users. Not a good idea. The extra time it takes to patch multiple Windows images will drain IT resources and negatively impact ROI. To efficiently scale VDI, maintain 1 Windows gold image.

How to educate your boss on cost savings of VDI

Posted by Tom Rose on Nov 12, 2014

This blog is an excerpt from the Unidesk eBook Ten Quick Tips for Scaling VMware Horizon View.

Those who have successfully virtualized their servers often go into their desktop virtualization project assuming the cost savings of VDI will be similar. That's not the case.

Server virtualization was easy to cost‐justify: consolidate a large number of under‐utilized small servers down to a small number of fully utilized, virtualized big servers. Save money.

Desktop virtualization is harder. By the time you add up the cost of servers, storage, and thin clients, then factor in licensing for software, the best you're likely to do is break even on capital costs compared to buying new PCs.

This is why many VDI projects have had trouble scaling - IT managers have been unable to educate senior IT management on cost savings of VDI beyond the soft benefits of enhanced mobility and security.

If you quantify cost savings, expanding your VDI deployment will be a much easier sell to your internal decision‐makers. Here's how to focus on the two primary sources of cost reduction: Energy Savings and OpEx Savings.

How to transition VDI management to Tier 1 IT staff

Posted by Tom Rose on Nov 6, 2014

This blog is an excerpt from the Unidesk eBook Ten Quick Tips for Scaling VMware Horizon View.

Virtual desktop deployments are often managed, at first, by the same Tier 2 or 3 IT staff members who designed and implemented VDI. However, keeping day-to-day management in the hands of server and network administrators or outside consultants is not scalable. Not only will you be paying more to manage virtual desktops than physical PCs (tossing ROI out the window in the process), but you will also lose valuable IT resources from forward-facing, strategic IT projects. If you transition VDI to the same Tier 1 staff who managed your PCs, you'll be able to scale your VDI deployment at a lower cost.

Give Your Knowledge Workers Persistent Virtual Desktops

Posted by Tom Rose on Oct 29, 2014

This blog is an excerpt from the Unidesk eBook Ten Quick Tips for Scaling VMware Horizon View.

With non‐persistent desktops, any settings, data, and user‐installed applications will be lost after the next patch or reboot. This might be acceptable for task workers. But it won’t be acceptable to knowledge workers who require a customizable desktop experience. Profile management helps preserve some changes, but cannot capture vital user‐installed applications and plug‐ins, and it adds additional management complexity and I/O overhead. The best way to scale VDI to knowledge workers is to give them persistent virtual desktops.

Posted by Tom Rose on Oct 20, 2014

This blog is an excerpt from the Unidesk eBook Ten Quick Tips for Scaling VMware Horizon View.

If you don't put your marketing hat on and sell VDI to your end users, you will likely encounter resistance that can torpedo your project. Savvy IT organizations are no longer mandating virtual desktop adoption. Rather than demanding acceptance, they are employing new methods to build consensus for VDI and gain end user buy-in.

How to Improve Graphics Performance in VDI

Posted by Tom Rose on Oct 8, 2014

This blog is an excerpt from the Unidesk eBook Ten Quick Tips for Scaling VMWare Horizon View.

VDI pilots typically start with basic applications. As the scope of the VDI deployment expands to more demanding users, VDI admins will look to improve the graphics performance of some applications. Some graphics intensive applications include: state, county, and city governments need GIS software such as ArcGIS for mapping and spatial analysis. Architectural services firms, building and construction firms, and engineering labs in colleges and universities require CAD software such as AutoCAD, Revit, and Civil 3D. Most marketing departments rely on Adobe Photoshop and Illustrator.

Improve VDI Performance by Increasing IO

Posted by Tom Rose on Oct 1, 2014

This blog is an excerpt from the Unidesk eBook Ten Quick Tips for Scaling VMware Horizon View.

Many enterprises are finding that moving Virtual Desktop Infrastructure (VDI) from pilot to production is harder than they thought. A VDI pilot that had great performance for 50 users is now not performing well for 100, 250, 1000 users and beyond.

VDI App Virtualization Mistakes: You Didn’t Account for Apps Needing to Communicate

Posted by Tom Rose on Jun 19, 2014

This blog is an excerpt from the Unidesk eBook Five Application Management Mistakes that Doom VDI Projects.

First-generation app virtualization tools use isolation technology to package apps in protective “bubbles,” effectively hiding them from Windows and other apps. This is perfect for running multiple versions of the same software (e.g. Java or Microsoft Access) on the same desktop. However, for the majority of apps that do not need to be isolated, and that need to share data, link to each other, and cross-communicate, this presents a major problem.
