PROJECT SUMMARY

A leading e-learning platform faced significant performance and scalability challenges due to a surge in user traffic, resulting in slow response times and system crashes. To address these issues, a comprehensive solution was implemented, including performance analysis and load testing using Apache JMeter, infrastructure upgrades with Docker and Kubernetes, and database optimization with SolarWinds and dbWatch. Continuous testing and monitoring were integrated into the CI pipeline using Jenkins and GitHub Actions. These measures led to a 40% reduction in response times, a 60% increase in user capacity, an 80% decrease in system crashes, and a 25% boost in user satisfaction.

CHALLENGES

Performance Bottlenecks: The system struggled to cope with the increased load, resulting in delays and disruptions during user interactions.
Scalability Concerns: The platform's infrastructure was not adequately equipped to handle the escalating number of concurrent users, leading to performance degradation.
Code Optimization Needs: The existing codebase required optimization to enhance efficiency and reduce response times.
4. Database Performance: Accessing and managing data efficiently was a challenge, impacting overall system responsiveness.
