12. How I'll Spend Seven Minutes
• Engineering decisions require data
• Good decisions require good data
• In the cloud, that means multiple measurements
13. Importance of Perf Benchmarks
• Validate design assumptions
• Evaluate alternatives
• Capacity planning / load tests
15. What Are You Measuring?
• Behavior of an application
• With a particular tuning
• Under some workload
• On a specific server type
• And system configuration
• From a particular hosting provider
• In a particular data center
• On a specific machine
• At a point in time
• Under some state of the network and supporting services
17. Test Many, Trust None
• Run each test many times
o On different instances
o At different times
• Aggregating across instances eliminates instance variability
• Comparing instances measures instance variability
