  1. 1. Reducing Long Tail Latencies in Geo-Distributed Systems

    Författare :Kirill Bogdanov; Dejan Kostic; Gerald Q. Maguire Jr.; Marc Shapiro; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud Computing; Geo-Distributed Systems; Replica Selection Algorithms; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Computing services are highly integrated into modern society. Millions of people rely on these services daily for communication, coordination, trading, and accessing to information. To meet high demands, many popular services are implemented and deployed as geo-distributed applications on top of third party virtualized cloud providers. LÄS MER

  3. 2. Enabling Fast and Accurate Run-Time Decisions in Geo-Distributed Systems : Better Achieving Service Level Objectives

    Författare :Kirill Bogdanov; Dejan Kostic; Gerald Q. Maguire Jr.; Bill Yoshimi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud Computing; Geo-Distributed Systems; Replica Selection Algorithms.; Molntjänster; Geodistribuerade system; Valalgoritmer för replikas; Computer Science; Datalogi;

    Sammanfattning : Computing services are highly integrated into modern society and used  by millions of people daily. To meet these high demands, many popular  services are implemented and deployed as geo-distributed applications on  top of third-party virtualized cloud providers. However, the nature of  such a deployment leads to variable performance. LÄS MER

  4. 3. Towards Elastic High-Performance Geo-Distributed Storage in the Cloud

    Författare :Ying Liu; Vladimir Vlassov; Peter Van Roy; Jim Dowling; Seif Haridi; Gregory Chockler; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : In this thesis, we have presented techniques and algorithms to reduce request latency of distributed storage services that are deployed geographically. In addition, we have proposed and designed elasticity controllers to maintain predictable performance of distributed storage systems under dynamic workloads and platform uncertainties. LÄS MER

  5. 4. Towards Unifying Stream Processing over Central and Near-the-Edge Data Centers

    Författare :Hooman Peiro Sajjad; Vladimir Vlassov; Johan Tordsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geo-distributed stream processing; geo-distributed infrastructure; edge computing; edge-based analytics; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : In this thesis, our goal is to enable and achieve effective and efficient real-time stream processing in a geo-distributed infrastructure, by combining the power of central data centers and micro data centers. Our research focus is to address the challenges of distributing the stream processing applications and placing them closer to data sources and sinks. LÄS MER

  7. 5. Methods and Algorithms for Data-Intensive Computing : Streams, Graphs, and Geo-Distribution

    Författare :Hooman Peiro Sajjad; Vladimir Vlassov; Keijo Heljanko; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stream processing; geo-distributed infrastructure; edge computing; streaming graph; dynamic graph; Informations- och kommunikationsteknik; Information and Communication Technology; Datalogi; Computer Science;

    Sammanfattning : Struggling with the volume and velocity of Big Data has attracted lots of interest towards stream processing paradigm, a paradigm in the area of data-intensive computing that provides methods and solutions to process data in motion. Today's Big Data includes geo-distributed data sources. LÄS MER
