“These chatty applications traverse a much longer path, and latency issues that might take place or congestion issues that might take place at the user will create corruptions in the database,” according to Parente. “With virtual desktop, the actual desktop environment is colocated in the same datacenter with that database, so the user is interacting not with the database directly but instead the presentation data is just being exchanged, so congestion will not impact the transaction of the application. It might impact performance a little bit for the user in terms of just their overall user experience, but it’s not going to cause data corruptions.”
Security issues must be considered when evaluating whether or not virtual desktop infrastructure is the appropriate choice for a company. Many security considerations related to virtual desktops are similar to that of cloud computing, says J.D. Sherry, vice president of Technology and Solutions at TrendMicro.
“The virtual desktop infrastructure allows IT to centrally manage [desktops], [and] incorporate a one-to-many security and patch-management process,” which is better from a security standpoint. It’s also cost effective “because they don’t have to spend a lot of capital expenditures to go buy a laptop, provision it, and give it to an end user,” notes Sherry.
But the virtual desktop infrastructure is vulnerable to the same threats that apply to the normal PC environment, so the traditional security measures must be in place, like best practices for password management and password delivery, notes Sherry.
Trend Micro’s product, DeepSecurity, enables companies with virtualization technologies to provide a tailored security solution for the virtual desktop environment at the level where the virtual machine is running, called the hypervisor level. And that “streamlines how you manage and protect those virtual desktop instances,” he says.
