## Introduction
Kruise Rollouts is a **Bypass** component that offers **Advanced Progressive Delivery Features**. Its support for canary, multi-batch, and A/B testing delivery modes can be helpful in achieving smooth and controlled rollouts of changes to your application, while its compatibility with Gateway API and various Ingress implementations makes it easier to integrate with your existing infrastructure. Overall, Kruise Rollouts is a valuable tool for Kubernetes users looking to optimize their deployment processes!
