  • 1. IISWC 2007 Panel Benchmarking in the Web 2.0 Era Prashant Shenoy UMass Amherst
  • 2. Questions for Position Statement
    • What do you see as the key emerging workloads?
    • What are the most important hardware and software challenges for these applications?
    • What are the benchmarking challenges for these workloads/systems?
    • How can university researchers contribute?
  • 3. Data Center Workloads
    • Different types of data centers
      • Internet data center
        • Youtube, Facebook, webmail
      • Enterprise data centers
        • Business, financial apps
      • Hosting platforms
        • 3rd party applications
          • Web, ecommerce, Amazon EC2
    • Workloads depends on type of data center
  • 4. Technology Trends
    • Virtualization
      • Data center apps run inside virtual servers
      • One or more VM mapped to a physical server
    • Why?
      • Flexible mapping of virtual to physical resources
      • Isolation
      • Vary resources allocations dynamically
      • Live migration
  • 5. Key Question
    • How does a data center workload impact a virtualized server and vice versa?
    • Scenario:
      • App running on physical server
      • Needs to move to a virtual server
      • What is the performance impact?
      • How do two VMs interact?
        • Memory, I/O not fully isolated.
        • CPU: impact on shared caches on multi-core cpus
  • 6. Hurdle
    • Many research ideas
    • But…
    • Few good workloads
      • SPECWEb, TPCW,
      • Rubis, Pet store
      • E-commerce centric, what about other types of data centers?
  • 7. Research Opportunity
    • Business apps
      • Apache openforbiz
    • Traces
      • Youtube
    • VM workloads / traces
    • Need workloads for “large” environments
      • Representative of tens or hundreds of machines
