Resource Provisioning In Large-Scale Self-Organizing Distributed Systems, M. Brent Reynolds
Theses and Dissertations
This dissertation researches the mathematical translation of resource provisioning policy into mathematical terms and parameters to solve the on-line service placement problem. A norm called the Provisioning Norm is introduced. Theorems presented in the work show the Provisioning Norm utility function and greedy, random, local search effectively and efficiently solve the on-line problem. Caching of placements is shown to reduce the cost of change but does not improve response time performance. The use of feedback control theory is shown to be effective at significantly improving performance but increases the cost of change. The theoretical results are verified using a decentralized, …

Theses and Dissertations
Cloud computing is one of the hottest topics in Information Technology accounting for growth in IT spending with global revenues surging to over $130 billion in 2013. According to the Federal CIO, the U. S. Government is considered the world’s largest purchaser of information technology with spending more than $76 billion per year. Since the commercial industry uses cloud computing to reduce costs, optimize business functions and collaborate on real-time data for decision making, should the Department of Defense implement cloud computing? Research examined the possibility that cloud computing is not seen as a viable technology and if the IT …
