A Gremlin Case Study
Visa Cross-Border Solutions faced the challenge of ensuring high availability for its complex web of over 120 microservices that handle cross-border financial transactions. With no dedicated function for resilience testing, the company needed a way to proactively find and fix failures before they caused outages for its global clients. To address this, they turned to the chaos engineering platform from Gremlin.
By implementing Gremlin, Visa Cross-Border Solutions built a dedicated staging environment to run automated resilience tests and weekly GameDays. This solution enabled them to standardize testing, uncover potential failures before they reached production, and create a company-wide culture of reliability. The results were significant, including the prevention of major P1 outages, the establishment of a 90% minimum reliability score for critical services, and the successful completion of over 60 GameDays to build engineering preparedness.
