About Our Client
The client is a rapidly growing SaaS company based in North America, offering a cloud-based video conferencing solution tailored for webinars, enterprise meetings, and hybrid events. With a surge in demand during remote work transitions, the platform needed to ensure seamless performance during large-scale virtual events.
Challenge
As the client onboarded enterprise customers and event organizers, they encountered critical scalability and performance challenges:
- Unstable Video Streams: High participant load caused random lags, dropped frames, and disconnects.
- API Bottlenecks: REST APIs handling meeting creation, authentication, and streaming controls showed latency spikes under load.
- Unpredictable Server Load Handling: Backend microservices failed to auto-scale effectively under concurrent access.
- Lack of Load Testing Infrastructure: No prior test simulations for 10,000+ concurrent participants.
- Security Concerns: API endpoints lacked proper rate-limiting and response validation for edge-case behaviors.
Solution
Celestial Infosoft delivered a complete QA initiative focused on scalability, real-time stress testing, and robust API assurance.
Key Features Delivered:
- API Performance Testing: Simulated high-concurrency usage via Postman and JMeter to identify API rate thresholds and latency.
- Video Stream Stress Testing: Custom scripts validated WebRTC stability across varied bandwidth and browser conditions.
- Load Simulation: Deployed cloud-based test agents to mimic thousands of real users joining sessions simultaneously.
- Backend Profiling: Monitored system behavior via New Relic to trace memory leaks, response time spikes, and service bottlenecks.
- Security QA: Conducted fuzz testing, authentication tests, and rate-limit verification for exposed APIs.
Project Highlights
- Simulated 25K+ Users joining multiple concurrent sessions using AWS-powered test orchestration.
- WebRTC Streams Validated across Chrome, Firefox, Safari, and Edge with bandwidth throttling.
- Service Auto-Scaling Optimized to handle load bursts without downtime.
- Secured API Gateways with intelligent throttling, improved input validation, and error handling.
Results
- 65% Latency Reduction across key APIs by restructuring endpoints and eliminating payload bloat.
- 95% Stream Uptime during test scenarios exceeding expected peak loads.
- Enabled 99.99% Uptime SLA for enterprise webinars and live events.
- Reduced Post-Release Defects with a regression-ready automated test suite.
