5. Issues Facing Developers 70% of Web Development Effort is Muck: Data Centers Bandwidth / Power / Cooling Operations Staffing Scaling is Difficult and Expensive: Large Up-Front Investment Invest Ahead of Demand Load is Unpredictable

6. Dream or Nightmare? Slashdot/Digg/TechCrunch Effect Rapid, unexpected customer demand/growth

7. Seasonal Spikes

8. More Seasonal Spikes Every year, we take the busiest minute of the busiest hour of the busiest day and build capacity on that, we built our systems to (handle that load) and we went above and beyond that. * -- Scott Gulbransen Intuit Spokesman * http://news.com.com/2100-1038_3-6177341.htmlhttp://news.com.com/2100-1038_3-6177341.html

9. Solution: Web-Scale Computing Scale capacity on demand Turn fixed costs into variable costs Always available Rock-solid reliability Simple APIs and conceptual models Cost-effective Reduced time to market Focus on product & core competencies

32. Sample Web-Scale Architecture GigaVox Media

33. Web-Scale Architecture

34. GigaVox Economics Implemented Amazon S3, Amazon EC2 and Amazon SQS in November 2006 Created an infinitely scalable infrastructure for less than $100 - building the same infrastructure themselves would have cost thousands of dollars Reduced staffing requirements - far less responsibility for 24x7 operations
