         • relies on the host machine's preexisting OS for resources.
         • unavoidable latency
   • Challenges
     • Performance
     • Security
     • Capacity Planning
   • cloud virtualization
     • more Security features
     • Fast computing
     • cost effective
     • backup of files
     • more storage
   • USES
