DESCRIPTION:Infrastructure-as-a-Service (IaaS) clouds have significant unt
 apped potential: The inherent diversity between different cloud providers 
 can be leveraged to improve reliability (via failure independence)\, secur
 ity (via different administrative domains)\, cost (via competition)\, and 
 performance (via geographic proximity). However\, exploiting cloud diversi
 ty faces challenges in interoperability\, control\, architectural support\
 , and resource management.\n\n\nIn this talk\, I will introduce the Librar
 y Cloud abstraction. Similar to the concept of a Library Operating System\
 , which links OS services into application’s address space\, a Library C
 loud encapsulates applications in a virtual cloud under users' full contro
 l\, and can incorporate one or more availability zones within the same or 
 across different providers. Users can perform privileged operations such a
 s live virtual machine (VM) migration and memory consolidation\, allowing 
 applications to manage geographically shifting workloads and handle VM con
 solidation transparently.  The Library Cloud abstraction allows transparen
 t and simultaneous control over a diverse set of cloud provider resources 
 such as Amazon EC2\, Google Compute Engine\, Microsoft Azure\, Rackspace\,
  VMWare vCloud Air\, HP Cloud\, and many private clouds.  I will present t
 he design and implementation of a prototype of a Library Cloud -- the Supe
 rcloud -- and demonstrate how applications can benefit from the Library Cl
 oud abstraction for several use cases.
