    Resource management for applications in large-scale systems.
    (2011-06) Cardosa, Michael David
    Recent years have seen increasing use of large-scale distributed systems such as Grids, Clouds, planetary-scale wide-area systems, large-scale enterprise clusters, and peer-to-peer systems. Such platforms attract applications such as scientific computing, data sharing and dissemination, data analysis and mining, and streaming multimedia. While these platforms scale well and their deployment cost is low, they present several challenges such as heterogeneous machine configurations and workloads, dynamism due to load fluctuations, and varying levels of connectivity based on the network topology. Users who submit distributed applications to be deployed in volunteer grids or looselycoupled systems desire a reliable deployment. Unfortunately, in these environments there exists uncertainty about the future state of system resources. Nodes chosen for deployment may become overloaded, causing resource requirements to be violated; resource requirements were originally established in applications to ensure high quality of service. Further, the emergence of MapReduce applications in cloud environments has presented several challenges. Managing the allocation of resources in the cloud for virtualized MapReduce clusters in order to optimize for energy savings and performance goals are difficult problems. In this dissertation, we present novel techniques for resource discovery in large-scale systems to facilitate the successful deployment of distributed applications, providing statistical guarantees to applications for their resource requirements. Further, we present novel techniques for the deployment of MapReduce applications in non-traditional environments, optimizing for energy-savings and performance goals.
