PagesJaunes

Yellow Pages - Top 10 French Website

In 2014, PagesJaunes began rolling out a redesigned application architecture. When traffic to the new site reached 30%, most system components failed within seconds. With only four weeks to migrate all traffic to the new site, they needed a way to quickly identify and fix the issues that traditional JMeter tests couldn't detect.

Successfully debugged critical system failures within one day
Consolidated multiple testing environments into a single production replica
Automated performance validation in CI/CD pipeline
Reduced production incidents through early detection
Enabled rapid debugging with 10-day traffic history
Eliminated complex JMeter scripting overhead
Streamlined development workflow and deployment process
"Today we keep 10 days of traffic in case of problems. We are one of the top 10 French websites which means a lot of traffic! GoReplay saved our life more than once! It was the only way to find very specific issues."

ResDiary

Restaurant Booking & Management Platform

Moving from RackSpace to Azure meant dealing with different hardware and infrastructure components like load-balancers, databases, and caches. The team needed to accurately plan capacity to avoid costly over-provisioning while ensuring the complex application with many integration points would function correctly under load.

Successfully migrated both Australian and UK infrastructure with zero downtime
Accurately estimated infrastructure requirements without over-provisioning
Automated testing process ran unsupervised for multiple days
Custom middleware enabled realistic testing while preventing external service issues
"When the time came to flip the switch, we had confidence that we wouldn't encounter any major catastrophes as we had caught them in our load tests. We were confident enough to run GoReplay totally unsupervised for days on end during the UK migration."

Zenika

Leading French agency

The team needed to replace a critical backend component that handled user communication credits and call authorizations. The functionality was complex, poorly understood, and the existing code was inadequately tested, holding back implementation of new business features.

Successfully replaced major legacy component with only 30 minutes downtime
Only one minor administrative bug detected in two weeks after deployment
Maintained full transparency for customers during migration
Validated new component against real production traffic patterns
Identified and fixed garbage collector issues during technical validation
Successfully migrated complex user credit and authorization system
"Apart from the 30 minutes of downtime required for data migration, we have been able to replace a major legacy component of our IS in full transparency for our customers. Only one minor bug was detected two weeks after experimental version was put into production. This was an administrative operation which had never been carried out in the double-run phases."

"Gor is really a nice tool and we use it to capture traffic. The traffic is then redirected to 2 versions so that we can compare their performance behavior under real-time production load mix conditions."

Stefan Friese

Test Framework team lead at here.com

"We've been using Gor to test our Content API at The Guardian and it's been great! Our API serves tens of millions of requests a day so being able to test changes with real traffic has been great. Thanks for the great library!"

Nicolas Long

Tech lead at theguardian.com

"Videology has been using Gor for at least a few months now. Traffic from our production load balancers stream a small slice of traffic to Gor which then streams it to multiple QA environments. We soak test our new and old versions of our web service and the compare their metrics to discover bugs. Great stuff!"

"Using GoReplay has transformed our testing process. The ability to test with real production traffic has given us unprecedented confidence in our deployments and system changes."
