Abstract
Conference Title: 2015 International Conference on Big Data and Smart Computing (BigComp) Conference Start Date: 2015, Feb. 9 Conference End Date: 2015, Feb. 11 Conference Location: Jeju, South Korea With large elastic and scalable infrastructures, the Cloud is the ideal storage repository for Big Data applications. Big Data is typically characterized by three V's: Volume, Variety and Velocity. Supporting these properties raises significant challenges in a cloud setting, including partitioning for scale out; replication across data centers for fault-tolerance; significant latency overheads due to consistency requirements; efficient traversal needs due to high update and velocity; and continuous maintenance in the presence of large variety of data representations. Last but not least, the storage of private data necessitates the ability to efficiently execute queries in a privacy preserving manner (P), without revealing user access patterns. In this paper we highlight these challenges and illustrate sample state of the art solutions.
