The Edge Stack API gateway enables organizations to streamline application development and management in a Kubernetes ecosystem by providing cost-effective solutions for continuous delivery testing. It allows for traffic shadowing, where real user traffic is directed at a new service or version of a service, while hiding the responses from users, enabling acceptance and nonfunctional tests on the cloaked service. Additionally, it supports traffic shifting, which directs part of its global traffic to systems under test, allowing for stress testing and gradual rollouts. The gateway also enables chaos engineering, where failure scenarios are simulated to learn how a system will perform under realistic use cases, load, and failure scenarios. This allows teams to enhance their continuous delivery testing strategies and improve the quality and reliability of their cloud-native applications.
