>> Trusted remote app execution: An alternative to carving out a separate business environment on personal devices is to simply move app execution off the device entirely, a technique that's been used in various forms -- VDI, terminal services, application streaming, browser apps -- on PCs for years. As with containerized apps, the advantage is that business apps appear in the personal workspace. Application streaming products like Citrix Receiver use a locally installed native client (the receiver) that provides faster app performance and a somewhat better user experience compared with a browser.
There are downsides, however. First, apps generally can't be used offline on mobile devices (though some products do offer caching on Windows devices). This shouldn't be much of an issue in the age of ubiquitous 3G/LTE connectivity. Second, the user experience may suffer if remote applications were developed for a PC with keyboard and mouse, not a touch-sensitive device.
While mobile device virtualization and compartmentalization technologies are still in flux, they make sense now for users accessing sensitive information or in regulated industries.
