Title: "Performance and Dependability Evaluation of Cloud Computing Systems"

by

Mr. Subrota Kumar Mondal


Abstract:
 
Cloud computing systems are inherently large scale, highly distributed, 
virtualized and operate in automated shared enviromments.  Thus, 
performance and dependability of cloud is affected by a large number of 
parameters.  Cloud resources need to be agile and reconfigurable in order 
to respond quickly to ever changing application demands and service 
requirements.  Significant research work has been done on designing cloud 
computing infrastructures in order to improve performance of cloud 
computing systems.

This work surveys the literature of various performance and dependability 
evaluation techniques and metrics of cloud computing systems.  We talk 
about the modeling of evaluation techniques and metrics in different 
fashions in order to highlight factors that affect the performance and 
dependability.  A good understanding of state-of-the art cloud 
infrastructures is necessary in order to provide better performance and 
depend- ability in the design of future cloud architectures.  Existing 
cloud computing systems consume a vast amount of energy and have a 
substantial impact on the environments, consequently we discuss how 
sustainable cloud reduces the environmental impact.  We discuss different 
proposals of sustainable cloud computing systems, and finally propose our 
own research on the evaluation of trade-offs amongst performance, 
dependability and sustainability.
