This talk is part of the System Research Seminar series
Abstract: This talk will present techniques for improving performance and availability of transaction-based applications which typically have Web front ends. While static Web content can generally be served at high rates, many of the real challenges occur in serving dynamic data requiring considerable back-end processing. The most significant bottleneck is often due to I/O and not to CPU limitations. While database management systems are commonly used, the overhead for many commonly used databases is significant. This talk will examine why this is the case and suggest methods for alleviating the problem.
For many commercial transaction processing systems, high availability is critically important. The talk will discuss techniques for achieving high availability and reducing recovery times after failures. Having multiple geographically distributed sites is one technique for achieving ability. This introduces problems in maintaining consistency between the various sites. The talk will present techniques for maintaining consistency among geographically distributed sites.
