Benchmarking de Infraestruturas de Virtualização para a Cloud

Abstract

Cloud computing has witnessed a tantalizing growth in recent years, with more and more companies migrating their previously in-house sys- tems to the Cloud, and Cloud Providers racing to match this growth by building newer and bigger datacenters. Nonetheless, this migration is still seen with dubious eyes by some companies, rightfully reticent in con d- ing their systems to external entities, over whom they possess little to no control. One of the reasons of this distrust has to do with the resilience of their systems. This dilemma set the foundation for this thesis. Our work sets the foundation for the development of a resilience benchmark for Cloud Computing systems, presents a watchdog mechanism capable of detecting problems and recovering the service of virtualized cloud systems and reports the results of various campaigns. The most important asset produced from this thesis are the 3 Fault Injection tools that we developed and from now on can support future research projects.
