Tom is the CEO and co-founder of Centrify Corporation, a software and cloud security provider that delivers unified identity services across datacenter, cloud and mobile.
While the mainframe was safely locked away in a glass box or an off-site datacenter, iPads and mobile phones often end up on the sofa or floor at home, with kids using them.
Larger storage capacity for a mobile device can rely on capacity in the cloud from a remote datacenter or on-board storage, such as in a 128 GB tablet.
When you add to this mix the explosion of mobile devices and app stores with a new generation of empowered applications, the locked down datacenter becomes a much smaller part of what IT has to manage.
