Virtual Distributed Computing Systems and Their Applications

Abstract

This dissertation thesis deals with the architecture, benchmarking, optimization and implementation of virtual distributed computing systems. Large distributed systems rep- resenting the performance background of all modern cloud computing architectures have become a very hot topic at present. This dissertation thesis o ers an introduction into modern technologies showing a rapid impact on the system performance. One of them is virtualization technology, whose real e ciency was a standalone part of the research. Large distributed systems consume a huge amount of electric power, therefore their optimization was also discussed. New ideas originated from the research were incorporated into the pro- posal of a new distributed system called Centr aln mozek univerzity (CMU). This system is able to manage and automatically optimize large virtualization infrastructures. It is also accessible to the end-users. This system is currently used in teaching many subjects and became a prototype of an educational system of new generation. In particular, the main contributions of the dissertation thesis are as follows: 1. Methodology, design and implementation of a new software benchmark utility able to measure virtualization e ciency of the distributed architecture. 2. New approach in a possible migration of the entire distributed systems between various data centres. 3. New distributed algorithm for virtual machines consolidation, rapidly reducing the energy consumption. 4. Design, description and implementation of the distributed virtualization system CMU.
