Case Study: Jack Henry drives innovation and saves costs with LaunchDarkly

Jack Henry drives innovation in financial services

Jack Henry, a financial services company, wanted to modernize its development and testing processes while improving scalability and rollout control. Using LaunchDarkly, the team added feature flags to support a phased migration of its email program from a single-threaded Windows service to a .NET Core application in Kubernetes.

LaunchDarkly helped Jack Henry adopt trunk-based development, improve testing, and roll out changes one email type at a time. The vendor’s solution also contributed to consolidating 102 virtual servers, generating savings of up to about $4,000 per month, while giving teams a framework to improve additional systems.
