When it comes to apps, Cisco's Ng advised companies to think thoroughly about the types of apps--native-to-device, browser-based, and virtual apps--they want to build and support. "In most cases, companies have a mix of these, depending on the complexity of functionalities needed and how sensitive their data is," he said.

Native apps are the most user-friendly but IT will need to do extra development work for the different OSs, he pointed out. Despite less flexibility offered to users, browser-based apps are highly portable and pose less security risks because data reside in the backend infrastructure rather than on the devices, said Ng.

Virtual apps--with both apps and data located inside a datacenter--are the easiest to support, but offers the least flexibility among the three types of apps, he said.
