  1. 1. Performance problem diagnosis in cloud infrastructures

    Författare :Olumuyiwa Ibidunmoye; Erik Elmroth; Guilliano Casale; Viktoria Fodor; Henrik Björklund; Umeå universitet; []
    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; Cloud Computing; OpenStack; Robust Optimization; Latency; Tabu Search; Resource Management; Resource Contention; QoS; Computer Science; Datavetenskap;

    Sammanfattning : High availability, cost effectiveness and ease of application deployment have accelerated the adoption rate of cloud computing. This fast proliferation of cloud computing promotes the rapid development of large-scale infrastructures. LÄS MER

  5. 4. Algorithms and Systems for Virtual Machine Scheduling in Cloud Infrastructures

    Författare :Wubin Li; Erik Elmroth; Johan Tordsson; Guillaume Pierre; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cloud computing; virtual machine; scheduling; systems; algorithms;

    Sammanfattning : With the emergence of cloud computing, computing resources (i.e., networks, servers, storage, applications, etc.) are provisioned as metered on-demand services over net- works, and can be rapidly allocated and released with minimal management effort. LÄS MER

  7. 5. Enabling Technologies for Management of Distributed Computing Infrastructures

    Författare :Daniel Espling; Erik Elmroth; Rizos Sakellariou; Umeå universitet; []
