   Sammanfattning : Modern virtualized Data Centers (DCs) require efficient management techniques to guarantee high quality services while reducing their economical cost. The ability to live migrate virtual instances, e.g. LÄS MER

3. 2. Traffic Management in Software-Defined Data Center Networks

   Författare :Cristian Hernandez Benet; Andreas Kassler; Boris Koldehofe; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SDN; data center; load-balancing; traffic management; EVPN; big data; programmable data plane; Computer Science; Datavetenskap;

   Sammanfattning : Traffic management in data centers is paramount to improving network and application performance, thereby improving the quality of service by reducing network congestion, packet loss, and latency. However, the deployment and configuration of traffic management techniques are challenging due to diverse data-center traffic characteristics, large data center topologies, and the interplay of different protocols at the routing, transport, and link layer.

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Data Center; Data Center Interconnection; EVPN; SDN; VM Migration; Computer Science; Datavetenskap;

   Sammanfattning : Live migration of Virtual Machines (VMs) has significantly improved the flexibility of modern Data Centers (DCs). Ideally, live migration ought to be seamless which in turn raises challenges on how to minimize service disruption and avoid performance degradation. LÄS MER

5. 4. 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

7. 5. 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.
