13. PROACTIVE LOAD PREDICTION & CODE PROFILING Challenge What will be the peak load on the portal? When exactly will the load on the portal be highest? What are the code optimization opportunities? Situation An HR communication and benefits content provider is signing up large-sized customers A large company wants access to the benefits portal for its 80,000 employees Harbinger Solution Historical usage analysis to predict the hour and date of peak load Writing test scripts and preparing test data to simulate load Server and SQL code profiling to identify bottlenecks and optimization opportunities Technologies & Tools Microsoft SQL Server 2005 Analysis Service Microsoft Visual Studio Team System 2008 (VSTS) Statistical spreadsheet modeling using time series and decision tree prediction theories Benefits Usage trend predicted accurately Web farm of eight load-balanced servers serving up to 9000 users per hour Only three years of data, and spreadsheet modeling had an error margin of just 10% Company tackling shorter employee enrollment period of 2 to 3 weeks instead of 2 months BOTTOM LINE Company adding large-sized customers and proactively planning for load in coming years www.harbinger-systems.com HSTC602
