HCL's End-to-End Performance Engineering Solutions help a leading Telecom Giant Improve its System Performance

The client is one of the world's leading Telecom giants in mobile handsets and GSM network technologies.

Complex and clustered system architecture with multiple participating elements involving external systems
Need to handle performance simulation for more than 1500 handsets across more than 120 global sites
Dependency of multiple global teams on performance data and simulation activities

Application support and maintenance services for a specific set of retail platform applications:

Used Agile Methodology to handle massive performance engineering activities
Devised base lining & subsequent benchmarking strategy to isolate the potential performance bottlenecks and generate the best configuration for system scalability
Created work-load with historical data analysis to simulate production system usage regarding usage pattern and scenarios, with user distribution server per minute
Completed scripting to simulate the application behavior with a variety of mobile handsets and new as well as legacy devices through the browser strings

Implemented Orthogonal Array approach to reduce the number of scripts and increase the coverage for 100 different countries and 1000+ products which includes new and old Products. In this way we simulated 20000+ unique requests as observed in production logs. Scripts count has reduced from 55 to 7 scripts with same Load model. Which ease us to maintain the scripts and achieve the desired goal. Also with this implementation we are able to achieve the 20000+ unique requests on target server.
Analyzed real production logs of 6 months which helps us to formulate the real end user behavior load on the target application system.
