  1. Rethinking Cost and Performance of Database Systems David Redding 4/6/11

  2. Introduction • Why I picked this article • What users want • Factors in building a Web Application • Old Database Architecture • New Proposed Database Architecture • Available Services 

  3. Why I picked this article • Internship with T. Rowe Price Storage Team • Learned about cost and optimizations being done on the hardware side • Managing disk arrays and various storage devices

  4. What users want • Zero Cost • Zero response time • Infinite throughput  • Infinite scalability • Users supported • Number of Machines added • 100% predictability • Cost • Performance • Availability for read and write • Flexibility

  5. Factors in building a database • Cost • No longer a one-time purchase • More hardware = More pay & Performance • Performance • Faster is better • Sustain a particular peak workload • Scalability • Step function • Predictability • Cost  • Performance • Consistency • Flexibility

  6. "Given a set of hardware resources and guaranteeing full data consistency, minimize the response time of requests and maximize the throughput of requests" Old Database Architecture

  7. "Given performance requirements of an application (peak throughput; maximum tolerable response times), minimize the required hardware resources and maximize the data consistency" New Proposed Database Architecture

  8. Available Services • Amazon Elastic Compute Cloud • Amazon Simple Storage Service • Sausalito
