How Performance Testing Reveals Hidden Bottlenecks in Microservices

from Software Testing with Fexingo: QA, Automation, and Reliable Software Engineering Hosted by Fexingo

Lucas and Luna explore a real-world case from a major e-commerce platform that discovered a 300-millisecond latency bottleneck in its checkout microservice during Black Friday load testing. They explain how the team used distributed tracing to pinpoint the issue, why traditional end-to-end tests missed it, and why every team should run performance tests with production-like traffic patterns. This episode gives you a concrete framework for diagnosing slowdowns before they hit users. #Microservices #PerformanceTesting #Latency #DistributedTracing #LoadTesting #BlackFriday #Ecommerce #Checkout #Bottleneck #QA #SoftwareTesting #Technology #FexingoBusiness #BusinessPodcast #LucasAndLuna #TestingInsights #DevOps #SRE Keep every episode free: buymeacoffee.com/fexingo
