| Data-backed web applications have stringent availability, performance and partition tolerance requirements that are difficult, sometimes even impossible, to meet using conventional database management systems. On the other hand, they typically are able to trade off consistency to achieve their goals. This has led to the development of specialized key-value stores, which are now used widely in virtually every large-scale web service. On the other hand, most web services also require capabilities such as indexing provided by a DBMS. We are witnessing an evolution of data serving as systems builders seek to balance these trade-offs. In this talk, I will survey some of the solutions that have been developed, including Amazon's S3 and SimpleDB and Yahoo!'s PNUTS, and discuss the challenges in building such systems as "cloud services", providing elastic data serving capacity to developers, along with appropriately balanced consistency, availability, performance and partition tolerance. |

Raghu Ramakrishnan is Chief Scientist for Audience and Cloud Computing at Yahoo!, and is a Research Fellow, heading the Web Information Management group. His work has influenced query optimization in commercial database systems and the design of window functions in SQL:1999. His paper on the Birch clustering algorithm received the SIGMOD 10-Year Test-of-Time award, and he has written the widely-used text "Database Management Systems" (with Johannes Gehrke). Ramakrishnan is a Fellow of the ACM and IEEE, and has received several awards, including the ACM SIGKDD Innovations Award, the ACM SIGMOD Contributions Award, a Distinguished Alumnus Award from IIT Madras, a Packard Foundation Fellowship in Science and Engineering, and an NSF Presidential Young Investigator Award. He is Chair of ACM SIGMOD, on the Board of Directors of ACM SIGKDD and the Board of Trustees of the VLDB Endowment. Ramakrishnan was Professor of Computer Sciences at the University of Wisconsin-Madison, and founder and CTO of QUIQ, a company that pioneered question-answering communities, powering Ask Jeeves' AnswerPoint as well as customer-support for companies such as Compaq. |
