Challenges
- Legacy Core-Java scripts were used to apply load on the application, increasing complexity.
- Faced multiple challenges while scripting for various smart devices supported by the application.
- Required strict success and availability criteria of 99.9%.
- Auto-scalable AWS cloud-based architecture with multiple vendors and monitoring tools further added to the complexity.
Solution
- Developed complex scripts using JMeter to dynamically emulate an online video player, replacing the legacy Core-Java scripts.
- Used various network sniffing tools like Fiddler and Wireshark across different platforms to capture API calls from smart devices.
- Conducted over 30 peak tests and several endurance tests lasting 120 hours each over a span of 12 months.
Value Delivered
- Achieved peak concurrency of 15,000 users while maintaining the stringent SLAs of 99.9% success and availability.
- Collaborated with the application architect to implement an all-in-one monitoring solution using Instana and Splunk, which provided a consolidated and in-depth view of all solution components, improving monitoring reach.
- The exhaustive endurance tests revealed data storage limitations in the application, which would reach maximum utilization in just 48 hours.
- Raised more than 100 performance defects in Jira, highlighting critical issues such as cache memory management problems, data integrity issues, and server-side errors caused by sticky sessions.
