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
