VDI in the Age of Covid-19: Remote Work and the Challenge of the Virtualized Client

These try occasions, not least as a result of company life must go on, which for hundreds of thousands of companies means delivering compute assets to staff at residence. Remote work is not an choice or an initiative – nearly in a single day it’s develop into a worldwide crucial. And identical to that, IT professionals worldwide face an enormous problem.

One potential answer is Virtual Desktop Infrastructure (VDI), which connects customers by way of net browser right into a digital machine occasion operating on a server someplace, be it inside an organization’s information facilities in Citrix or VMware, or supplied by a cloud platform equivalent to AWS or Azure.

Of course, the idea of distant entry to a pre-configured digital desktop shouldn’t be new. I can keep in mind how on one in all my first analyst assignments, some 20 years in the past, I used to be tasked to find out the whole price of possession (TCO) of thin-client methods towards their native, rich-client desktop equivalents. Twenty years later, I return to this abruptly pressing matter to ask a few of our analysts what’s new about VDI and the way it may handle our present problem.

First off, VDI continues to be very a lot a factor, with know-how that continues to evolve and leverage hosted, cloud fashions.

“Every firm I’ve labored with within the final 15 years has began some type of VDI atmosphere – particularly now that groups are upgrading or changing legacy Citrix environments,” says Iben Rodriguez, whose day job crosses quite a lot of enterprise purchasers within the monetary and authorities sectors. “We had an organization come to us for an growth of their 1000-user AWS Workspaces answer, and one other buyer is shifting 3000 customers to a Microsoft VDI answer away from Citrix.”

He says {that a} 2009 person deployment on VMware Horizon VDI nonetheless runs on Cisco and EMC {hardware}.

And Iben contends that there’s nonetheless loads of TCO to be present in VDI deployments. Even if endpoint {hardware} costs have dropped, price overhead can nonetheless be vital in an unmanaged atmosphere. The decrease prices enabled by centralized management seems to be the compelling motive to maneuver to a VDI strategy. Add to that the safety and administration advantages throughout each the distant desktop and the communications hyperlink, and the advantages add up. Control permits simplicity, which reduces threat —all good causes to undertake a virtualized mannequin.

However, centralized management may cause conflicts with the person base, which is after all of the group being served. And that battle, says Andrew Brust, is all about finish customers wanting management.

“While VDI from old fashioned Citrix and Remote Desktop to newer cloud-hosted platforms are cool, individuals discover that desktop-on-desktop will get complicated and no person loves it. Just as individuals like apps on their telephones, individuals like to put in software program on their laptops and don’t love delegating management of that away — even when IT does.”

There’s one other difficulty: Today’s ”excellent” desktop configuration is probably not fairly so excellent in six, 12 or 18 months. Management methods have a decay curve, which must be factored into the preliminary enterprise case and strategy.

“The gold picture downside is actual, and an actual headache, says Ned Bellavance, who additionally warns that correct {hardware} wanted to assist good VDI might be pricey. “And it doesn’t assist with overwhelmed VPNs or disconnected eventualities.”

The reply, partially, lies in deciding what’s value fixing, and what ought to stay exterior of centralized management. “When you issue stuff out that’s transportable, it scales properly,” says Brust. “When you attempt to replicate the complete stack together with the non-public OS and atmosphere, not a lot.

He provides: “In basic, centralizing and templatizing for large-scale deployment of issues which can be primarily based on private [computing] environments can hit glitches.”

If this appears like a compromise, that’s as a result of it’s — no less than within the quick time period. Looking additional out, we are able to be taught from one other area — Mobile Device Management (MDM) – which has advanced to assist organizations management and safe smartphones and handheld gadgets.

“Many conventional MDM options moved to a cellular software administration paradigm, as a result of controlling the gadget is a ache,” says Bellavance. Core to the brand new MDM strategy is using containers.

Containers, basically stand-alone software modules that may run wherever, are having an affect throughout the know-how area — not least in massively scalable, cloud-based software architectures. Netflix, for instance, is the poster little one for containerization.

As it seems, containers are additionally very helpful on the subject of balancing management with person flexibility.

“It’s simpler to regulate the app as a container on cellular gadgets,” Ned continues. “Ideally we’d convey an identical container strategy to desktop working methods, and also you wouldn’t must mess about with native gadget administration.”

Microsoft is an adopter of this mannequin, with its InTune app safety product, and the corporate has leveraged containers to allow Windows to run on ARM processors.

“The container strategy (broadly talking) has been liberating in plenty of methods. It’s made issues work that appeared totally insoluble for a really very long time,” says Brust.

So, how can organizations undertake VDI in the present day, whereas on the identical time planning for the longer term? The reply is to be life like on price planning within the quick time period, notably by way of administration and assist overhead created by the large improve in distant work. At the identical time, IT organizations ought to look ahead to advances round containerization and the way it can allow an optimum mix of end-user flexibility and centralized management.
