Dynamic execution platforms over federated clouds

摘要: The increasing needs for computing power have led to parallel and distributed computing, which harness the of large infrastructures in a concurrent manner. Recently, virtualization technologies increased popularity, thanks hypervisors improvements, shift multi-core architectures, spread Internet services. This has emergence cloud paradigm offering resources an elastic, on-demand approach while charging only consumed resources. In this context, thesis proposes four contributions leverage multiple clouds. They follow two directions: creation elastic execution platforms on top federated clouds, inter-cloud live migration using them dynamic We propose mechanisms efficiently build clouds sky federation approach. Resilin is system creating managing MapReduce allowing easily execute computations without interacting with low level interfaces. reconfigure virtual network presence migration, implemented ViNe from University Florida. Finally, Shrinker protocol improving clusters over wide area networks by eliminating duplicated data between machines.
