Why VDI is here to stay

VDI has led an up-and-down existence. Once heralded as the next great evolution in virtualization when it hit the scene more than a decade ago, VDI was eventually labeled a failure by many. In reality, the future of VDI is still very much alive.

To find out just how viable VDI is at this point, it’s important to look at the reasons many people cited in saying the technology was doomed to fail and see what, if anything, has changed.

VDI is cost-prohibitive

In the early days, the overall cost of a virtual desktop could be as much as five times higher than that of a comparable physical desktop, according to some estimates. In fact, virtual desktops were once so ridiculously expensive that they were something of a status symbol for the few organizations that chose to use them in production.

Today, the debate over whether it is less expensive to deploy physical or virtual desktops rages on. VDI vendors are quick to tell potential customers that virtual desktops cost less than physical desktops, while others claim the opposite.

Regardless of whether virtual desktops or physical desktops have a lower total cost of ownership, one thing is certain: The fact that people are even debating which desktop type is less expensive serves as proof that the cost of VDI has dropped tremendously.

The overall cost reduction can be attributed to three main factors:

  • Friendlier licensing terms
  • Moore’s Law: In the context of VDI, Moore’s Law means IT can add more virtual desktops per host server as the technology matures.
  • Purpose-built hyper-converged infrastructure: HCI lowers the cost of long-term operational tasks by combining compute, storage and networking in one piece of hardware.

Enterprise desktops are complex

There is far more to an enterprise desktop — physical or virtual — than just the OS. There are many other components IT must consider. Some of these components include applications, device drivers and user profiles.

At one time, making a change to any one of these or other desktop components could have meant building and deploying a brand-new desktop image. As such, many people considered virtual desktop management to be far too labor-intensive for the technology to ever be practical.

It is increasingly common for IT to break down virtual desktops into a series of virtualized subcomponents.

Today, however, there is no reason IT has to base virtual desktops on a single, monolithic and frequently updated image. It is increasingly common for IT to break down virtual desktops into a series of virtualized subcomponents. This approach works similarly to containerization.

For example, IT might virtualize applications so it can maintain them without having to worry about the OS image. Likewise, IT can break off the user profile into a virtualized layer, making it possible to achieve the illusion of persistence without affecting the desktop OS. In any case, layering addresses the challenges of enterprise desktop complexity.

Performance

An early VDI implementation might work fine for lightweight apps, such as word processors and spreadsheets, but it would likely have trouble coping with anything graphically or computationally intensive. Even the simple act of playing a YouTube video could bring a VDI deployment to its knees.

Today, VDI performance is generally far better. Yes, Moore’s Law plays into this, but there are also some other factors. For instance, VDI has existed for long enough that vendors have gotten a lot better at performance-tuning their VDI software. Likewise, vendors such as VMware and Microsoft added features designed to ensure performance and stability.

For example, IT can throttle virtual desktops to prevent a user from generating a workload that affects other virtual desktops. In addition, IT can map virtual desktops running graphically intensive workloads to physical graphics processing units to provide graphical performance that is nearly as good as what users would expect on a physical desktop.

Had this case for around 6 months now, haven’t used once and only unboxed it. Was going to be doing a hard line build in this but decided to do a traditional build due to limited mATX and ITX ryzen boards.

DoD exposed data stored in massive AWS buckets

Once again, Department of Defense data was found publicly exposed in cloud storage, but it is unclear how sensitive the data may be.

Chris Vickery, cyber risk analyst at UpGuard, based in Mountain View, Calif., found the exposed data in publicly accessible Amazon Web Services (AWS) S3 buckets. This is the second time Vickery found exposed data from the Department of Defense (DoD) on AWS. The previous exposure was blamed on government contractor Booz Allen Hamilton; UpGuard said a now defunct private-sector government contractor named VendorX appeared to be responsible for building this database. However, it is unclear if VendorX was responsible for exposing the data. Vickery also previously found exposed data in AWS buckets from the Republican National Committee, World Wrestling Entertainment, Verizon and Dow Jones & Co.

According to Dan O’Sullivan, cyber resilience analyst at UpGuard, Vickery found three publicly accessible DoD buckets on Sept. 6, 2017.

“The buckets’ AWS subdomain names — ‘centcom-backup,’ ‘centcom-archive’ and ‘pacom-archive’ — provide an immediate indication of the data repositories’ significance,” O’Sullivan wrote in a blog post. “CENTCOM refers to the U.S. Central Command, based in Tampa, Fla. and responsible for U.S. military operations from East Africa to Central Asia, including the Iraq and Afghan Wars. PACOM is the U.S. Pacific Command, headquartered in Aiea, Hawaii and covering East, South and Southeast Asia, as well as Australia and Pacific Oceania.”

UpGuard estimated the total exposed data in the AWS buckets amounted to “at least 1.8 billion posts of scraped internet content over the past eight years.” The exposed data was all scraped from public sources including news sites, comment sections, web forums and social media.

“While a cursory examination of the data reveals loose correlations of some of the scraped data to regional U.S. security concerns, such as with posts concerning Iraqi and Pakistani politics, the apparently benign nature of the vast number of captured global posts, as well as the origination of many of them from within the U.S., raises serious concerns about the extent and legality of known Pentagon surveillance against U.S. citizens,” O’Sullivan wrote. “In addition, it remains unclear why and for what reasons the data was accumulated, presenting the overwhelming likelihood that the majority of posts captured originate from law-abiding civilians across the world.”

Importance of the exposed DoD data

Vickery found references in the exposed data to the U.S. Army “Coral Reef” intelligence analysis program, which is designed “to better understand relationships between persons of interest,” but UpGuard ultimately would not speculate on why the DoD gathered the data.

Ben Johnson, CTO at Obsidian Security, said such a massive data store could be very valuable if processed properly.

“Data often provides more intelligence that initially accessed, so while this information was previously publicly available, adversaries may be able to ascertain various insights they didn’t previously had,” Johnson told SearchSecurity. “What’s more of a problem than the data itself in this case is that this is occurring at all — showcasing that there’s plenty of work to do in safeguarding our information.”

Rebecca Herold, president of Privacy Professor, noted that just because the DoD collected public data doesn’t necessarily mean the exposed data includes accurate information.

“Sources of, and reliability for, the information matters greatly. Ease of modifying even a few small details within a large amount of data can completely change the reality of the topic being discussed. Those finding this information need to take great caution to not simply assume the information is all valid and accurate,” Herold told SearchSecurity. “Much of this data could have been manufactured and used for testing, and much of it may have been used to lure attention, as a type of honeypot, and may contain a great amount of false information.”

Herold added that the exposed data had worrying privacy implications.

“Just because the information was publicly available does not mean that it should have been publicly available. Perhaps some of this information also ended up being mistakenly being made publicly available because of errors in configurations of storage servers, or of website errors,” Herold said. “When we have organizations purposefully taking actions to collect and inappropriately (though legally in many instances) use, share and sell personal information, and then that information is combined with all this freely available huge repositories of data, it can provide deep insights and revelations for specific groups and individuals that could dramatically harm a wide range of aspects within their lives.”
