A very real problem
If CIOs or other leaders haven't experienced this, it probably isn't easy to remember that connectivity in the US not only lags other highly connected nations, but is still fairly well limited to major population areas and transportation avenues. When you work with folks in very rural parts of this nation, this problem is very real. When you travel to less developed countries on a regular basis, this problem is very real. Herein lies the dilemma around VDI and not storing data on the mobile device. If your employee doesn't have network access, they are not able to work if there's nothing cached locally. When building a mobile strategy, security of the device must be balanced so that productivity isn't completely hampered in the quest to keep data safe and secure on the server.
