DESCRIPTION:Prashant SHENOY\, University of Massachusetts\nModern distribu
 ted applications are built using the implicit assumption that the underlyi
 ng data center servers will be stable and normally available\, barring for
  occasional faults.  In many emerging scenarios\, however\, data centers 
 and clouds only provide transient\, rather than continuous\, availability 
 of their servers. Transiency in modern distributed systems arises in many 
 contexts\, such as green data centers powered using renewable intermittent
  sources  cloud platforms that provide lower-cost spot server instances w
 hich can be revoked from their users\, or smart data centers that voluntar
 ily curtail their energy usage when signaled by the smart electric grid.\n
 In this talk\, I will argue for treating  transiency as a first-class des
 ign concern when  building modern distributed systems and applications. 
  I will present bounded virtual machine  migration as a general mechanism
  for handling transiency in a broad class of systems and discuss how such 
 a mechanism can be employed to design higher-level techniques to handle tr
 ansiency in data centers and cloud systems. I will end with some prelimina
 ry results that demonstrate the benefits and feasibility of our approach.
