Case Study: one of India's leading payment gateway companies achieves real-time monitoring at 1.4B events/day with Elastic

one of India's leading online payment gateway companies monitors 1.4 billion events a day with Elastic

The customer, one of India's leading online payment gateway companies, faced significant observability challenges due to its platform built on over 25 microservices. When transactions failed, engineers could not trace them across services, lacked per-service latency monitoring, and had no alerts for service restarts. This lack of visibility meant troubleshooting was slow and reactive. The company partnered with vendor Elastic to implement a central log management solution using the Elastic Stack to gain real-time insights.

Elastic deployed a dedicated log monitoring environment sized for the customer's massive production load, which processes 1.4 billion events (500 GB) daily. The solution enabled engineers to trace any failed transaction end-to-end using a trace ID and monitor each microservice's health. As a result, troubleshooting time was reduced from hours to minutes, critical alerts were established, and the platform's reliability earned the team's trust, allowing them to confidently move more critical workloads onto Elastic.
