Title: Cloud based Active Archiving Solution for Databases


Cloud computing offers an exciting opportunity to bring on-demand 
applications to customers and is being used for delivering hosted 
services over the Internet and/or processing massive amount of data for 
business intelligence. In this talk, we will discuss the architecture of 
cloud computing, MapReduce, and Hadoop. We will then discuss how the 
cloud infrastructure can be used for data management services, how the 
massive amount of data can be processed over cloud for various business 
intelligence applications, and how the cloud can be used for 'Active' 
Data Archival for near real-time data access. We discuss various issues 
concerning the active archive system including schema modification, 
query federation, query optimization, access control and data 
provenance. Using TPC-DS benchmark data, we present evaluation results 
that shows the ability of our system to seamlessly query archive data 
along with data stored in the warehouse in order of minutes compared to 
hours required to move the data into the warehouse from traditional 
archival systems.
