He points out that adding too many firewalls and other endpoint protections that aren’t specifically designed for virtual desktop infrastructure can cause latency issues. “When you don’t put the right security solutions in place, it could impact performance, which makes end users unsatisfied and increases IT helpdesk tickets, people calling in and saying ‘I can’t get access to my computer or it’s slow,’ and [that] creates a lot of strain on the folks who are running the infrastructure because they’re constantly dealing with problems and solutions that don’t work cohesively together,” notes Sherry.
Of course, virtual desktop users are unable to complete work offline, which could be viewed as a drawback. Sherry says that it’s up to a company to decide whether that architecture works for them.
Another issue is one of persistent versus nonpersistent desktop. With the persistent state, when users log in, they go back to where they left off. This requires more server storage space and backup on the part of the company.
“The persistent side is usually the route that organizations are going. They’re connected, the profile, the settings are persistent from what I would call login to login, and there isn’t a new instance of that virtual machine every single time. It’s already running; it stays running; it doesn’t shut down,” he states. “Persistent desktops themselves are a more natural experience for users who are accustomed to using a laptop or desktop.”
