"Simulation Techniques for Knowledge Management in Clouds & programs for advancement of women at TU Vienna";
Talk: Minisymposium "Women in Simulation Technology and Science" at SimTech 2011,
Stuttgart, Germany (invited);
The first part of the talk will focus on application of simulation technologies for the knowledge management in Clouds. The emergence of Cloud Computing raises the question of dynamically allocating resources of physical (PM) and virtual machines (VM) in an on-demand and autonomic way. For the efficient use of Cloud Computing infrastructures following - partly contradicting goals - have to be fulfilled: first, achieving low violation rates of Service Level Agreements (SLA) that define non-functional goals between the Cloud provider and the customer; second, achieving high resource utilization; and third achieving the first two issues by as few time- and energy consuming reallocation actions as possible. To achieve these goals we evaluated two knowledge management techniques, namely Case Based Reasoning (CBR) and rule based approach. Thereby, we considered reactive actions ranging from changing the configuration of VMs, over migrating them to other PMs, to outsourcing applications to other Cloud providers. For the evaluation of both approaches we developed a novel simulation engine. Simulated results reveals major improvements as compared to recent related work considering SLA violations, resource utilization and action efficiency, as well as time performance.
Second part of the talk will discuss recent programs for advancement of women at TU Vienna. In particular we will address recent challenges as well as first success stories.
