  1. 6. May the power be with you : managing power-performance tradeoffs in cloud data centers

    Författare :Jakub Krzywda; Erik Elmroth; Per-Olov Östberg; Ahmed Ali-Eldin; Tarek F. Abdelzaher; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cloud computing; data centers; power efficiency; power budgeting; application performance;

    Sammanfattning : The overall goal of the work presented in this thesis was to find ways of managing power-performance tradeoffs in cloud data centers. To this end, the relationships between the power consumption of data center servers and the performance of applications hosted in data centers are analyzed, models that capture these relationships are developed, and controllers to optimize the use of data center infrastructures are proposed.

  2. 7. Toward Next-generation Data Centers : Principles of Software-Defined “Hardware” Infrastructures and Resource Disaggregation

    Författare :Amir Roozbeh; Dejan Kostic; Gerald Q. Maguire Jr.; Fetahi Wuhib; Boris Grot; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cloud computing; next-generation data centers; resource disaggregation; TCO; last level cache; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : The cloud is evolving due to additional demands introduced by new technological advancements and the wide movement toward digitalization. Therefore, next-generation data centers (DCs) and clouds are expected (and need) to become cheaper, more efficient, and capable of offering more predictable services. LÄS MER

    Författare :Irvin Homem; Theo Kanter; Panagiotis Papapetrou; Rahim Rahmani; Fredrik Björck; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer forensics; network forensics; mobile devices; mobile forensics; cloud computing; semantic web; hypervisors; virtualization; remote acquisition; automation; evidence analysis; correlation; P2P; bittorrent; datalogi; Computer Science; informationssäkerhet; Information Systems Security;

    Sammanfattning : Cybercrime and related malicious activity in our increasingly digital world has become more prevalent and sophisticated, evading traditional security mechanisms. Digital forensics has been proposed to help investigate, understand and eventually mitigate such attacks. LÄS MER

  4. 9. Workload characterization, controller design and performance evaluation for cloud capacity autoscaling

    Författare :Ahmed Ali-Eldin Hassan; Erik Elmroth; Johan Tordsson; Prashant Shenoy; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cloud computing; autoscaling; workloads; performance modeling; controller design;

    Sammanfattning : This thesis studies cloud capacity auto-scaling, or how to provision and release re-sources to a service running in the cloud based on its actual demand using an auto-matic controller. As the performance of server systems depends on the system design,the system implementation, and the workloads the system is subjected to, we focuson these aspects with respect to designing auto-scaling algorithms.

  5. 10. Managing Applications and Data in Distributed Computing Infrastructures

    Författare :Salman Zubair Toor; Sverker Holmgren; Dirk Düllmann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distributed Computing Infrastructures; Grids; Clouds; Application Management; Distributed Storage; Resource Allocation; Beräkningsvetenskap; Scientific Computing;

    Sammanfattning : During the last decades the demand for large-scale computational and storage resources in science has increased dramatically. New computational infrastructures enable scientists to enter a new mode of science, e-science, which complements traditional theory and experiments. LÄS MER
