eHarmony.com uses AppDynamics to keep their Node.js applications running healthy with zero outages
eHarmony is the #1 trusted online dating site for relationship-minded singles. Since launching in 2000, eHarmony uses patented algorithms and mathematical models to find that perfect match among their members that are most likely to enjoy a healthy long-term relationship. With an average of 438 eHarmony members being married every day, eHarmony looks to AppDynamics to help deliver mission-critical performance for their consumer-facing applications.
Having a disconnect among the distributed teams became risky in tracking latency and errors among a distributed transaction. Baal soon came to realize there were too many dashboards with decoupled monitoring solutions causing an inefficiency in productivity. “Before a product such as AppDynamics, it used to take several people looking at several different monitoring solutions, comparing numbers to find any problem with our system.”
AppDynamics gave Baal and his team the critical insight into the distributed nature of their transactions, starting with the public-facing Node.js layer, through the various databases and cache backends, and into the internal micro-services they consume. If a transaction suffered a bottleneck, they were given the insight to know exactly where to find the latency and which team was to blame. Now, “any on-call person has one place to look and can pinpoint where we are having an issue and contact the right person right away”, says Baal.
The new capabilities of AppDynamics gave Baal the confidence to complete their Node.js transition and successfully launch their new public cluster. “I can actually say we've had no outages in production on a Node.js cluster, since we've been porting over, and I can credit a large part of that due to the monitoring of AppDynamics.”
Enabling Baals' teams and providing support was an essential factor in his commitment to AppDynamics. Supporting the rollout of AppDynamics across their fleet of services allowed the eHarmony teams to focus on their primary responsibilities: building their core business and delivering an exceptional user experience to their customers.
