  1. 1. Performance problem diagnosis in cloud infrastructures

    Detta är en avhandling från Umeå : Department of Computing Science, Umeå University

    Författare :Olumuyiwa Ibidunmoye; Umeå universitet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Systems Performance; Performance anomalies; Performance bottlenecks; Cloud infrastructures; Cloud Computing; Cloud Services; Cloud Computing Performance; Performance problems; Performance anomaly detection; Performance bottleneck identification; Performance Root-cause Analysis; Computer Systems; datorteknik; Computer Science; datalogi;

    Sammanfattning : Cloud datacenters comprise hundreds or thousands of disparate application services, each having stringent performance and availability requirements, sharing a finite set of heterogeneous hardware and software resources. The implication of such complex environment is that the occurrence of performance problems, such as slow application response and unplanned downtimes, has become a norm rather than exception resulting in decreased revenue, damaged reputation, and huge human-effort in diagnosis.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Digital Forensics; Machine Learning; Computer Forensics; Network Forensics; Predictive Modelling; Distributed Systems; Mobile Devices; Mobile Forensics; Memory Forensics; Android; Semantic Web; Hypervisors; Virtualization; Remote Acquisition; Evidence Analysis; Correlation; P2P; Bittorrent; data- och systemvetenskap; Computer and Systems Sciences;

    Sammanfattning : Digital Forensics is used to aid traditional preventive security mechanisms when they fail to curtail sophisticated and stealthy cybercrime events. The Digital Forensic Investigation process is largely manual in nature, or at best quasi-automated, requiring a highly skilled labour force and involving a sizeable time investment. LÄS MER

    Sammanfattning : We are increasingly dependent on Internet as a large aspect of our daily life is now handled via online applications. Recent years we have seen several large-scale crises. This has made crisis-related research on Internet applications important. LÄS MER

  4. 4. Efficient Memory Modeling During Simulation and Native Execution

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Nikos Nikoleris; Uppsala universitet.; Uppsala universitet.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; performance analysis; cache performance; multicore performance; memory system; memory bandwidth; memory contention; performance prediction; multi-threading; multiprocessing systems; program diagnostics; commodity multicores; multithreaded program resource requirements; performance counters; scalability bottleneck; scalability improvement; Computer Science; Datavetenskap;

    Sammanfattning : Application performance on computer processors depends on a number of complex architectural and microarchitectural design decisions. Consequently, computer architects rely on performance modeling to improve future processors without building prototypes. LÄS MER

  5. 5. Performance anomaly detection and resolution for autonomous clouds

    Detta är en avhandling från Umeå : Umeå University

    Författare :Olumuyiwa Ibidunmoye; Umeå universitet.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud Computing; Distributed Systems; Performance Management; Anomaly Detection; Quality of Service; Performance Analytics; Machine Learning; Computer Systems; datorteknik; administrativ databehandling; Computing Science; Computer Science; datalogi;

    Sammanfattning : Fundamental properties of cloud computing such as resource sharing and on-demand self-servicing is driving a growing adoption of the cloud for hosting both legacy and new application services. A consequence of this growth is that the increasing scale and complexity of the underlying cloud infrastructure as well as the fluctuating service workloads is inducing performance incidents at a higher frequency than ever before with far-reaching impact on revenue, reliability, and reputation.
