LaunchDarkly has integrated with AWS PrivateLink, allowing mutual customers to reduce data transfer costs and improve security by keeping their traffic within the AWS network. This integration is particularly beneficial for users of LaunchDarkly's data-intensive product offerings, as it can significantly lower event data egress costs and enforce stricter firewalls. The integration works by providing an endpoint service that enables direct data transfer from AWS to LaunchDarkly without using a regular internet connection.
