Document Summary

Eight hardware trends: the mobile digital platform. Cell phones and smartphones have assumed data transmission, web sur ng, e-mail, and. Smartphones and tablets are increasingly used for business: consumerization of it and byod. Technology emerges in the consumer market and then spreads into business organizations. New challenges for the it department: security, software availability, ownership: grid computing. Involves connecting geographically remote computers into a single network capable of working in parallel on business problems that require short term access to large computational capacity. Rather than purchase huge mainframes or super computers, rms can chain together thousands of smaller desktops clients into a single computing grid: virualization. Presents computing resources so that they can be accessed in ways that are not restricted by con guration. Allows multiple operating systems to run on one machine. Increases server utilization rates from 10-15 to 70 percent of capacity: cloud computing.
