Title: Cost-effective big data management in clouds

Abstract:

In this talk, I will first give an overview of my research in the areas of cloud computing, data management and workflow technologies, etc. Then I will talk about a more specific topic of the cost-effectiveness with regard to data management in clouds and share some of my experience in doing research.

Based on the pay-as-you-go model in cloud computing, large generated application data can be flexibly stored, re-computed and transferred with multiple cloud service providers. In this talk, I will present a novel algorithm that can calculate the minimum cost for storing and regenerating data in multiple clouds, i.e. whether data should be stored or deleted, and furthermore where to store or to regenerate whenever they are reused. It also achieves the best trade-off among computation, storage and bandwidth costs in clouds, which are three key factors for the cost of cloud resources.
