  1. 1. Capacity Scaling for Elastic Compute Clouds

    Författare :Ahmed Ali-Eldin; Erik Elmroth; Johan Tordsson; Alexandru Iosup; Umeå universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datalogi; Computer Systems; datorteknik;

    Sammanfattning : AbstractCloud computing is a computing model that allows better management, higher utiliza-tion and reduced operating costs for datacenters while providing on demand resourceprovisioning for different customers. Data centers are often enormous in size andcomplexity. LÄS MER

  3. 2. 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 :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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.

  4. 3. Enabling Technologies for Management of Distributed Computing Infrastructures

    Författare :Daniel Espling; Erik Elmroth; Rizos Sakellariou; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; grid computing; cloud computing; accounting; billing; contextualization; monitoring; structure; fairshare; scheduling; federated; Computer Science; datalogi;

    Sammanfattning : Computing infrastructures offer remote access to computing power that can be employed, e.g., to solve complex mathematical problems or to host computational services that need to be online and accessible at all times. LÄS MER

  5. 4. Metadata Management in Multi-Grids and Multi-Clouds

    Författare :Daniel Espling; Erik Elmroth; Erwin Laure; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; grid computing; cloud computing; accounting; billing; metadata; monitoring; structure; fairshare; scheduling; federated; Computer Science; datalogi;

    Sammanfattning : Grid computing and cloud computing are two related paradigms used to access and use vast amounts of computational resources. The resources are often owned and managed by a third party, relieving the users from the costs and burdens of acquiring and managing a considerably large infrastructure themselves. LÄS MER

  7. 5. Capacity allocation mechanisms for grid environments

    Författare :Peter Gardfjäll; Erik Elmroth; Bo Kågström; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Grid computing; capacity allocation; allocation enforcement; accounting; Grid-wide fairshare scheduling; Web services; Computer science; Datavetenskap;

    Sammanfattning : During the past decade, Grid computing has gained popularity as a means to build powerful computing infrastructures by aggregating distributed computing capacity. Grid technology allows computing resources that belong to different organizations to be integrated into a single unified system image – a Grid. LÄS MER
