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

Client Information

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

Business Objective

• 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

HCL Solution

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

Business Benefits

• 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.
