You can use Alibaba Cloud Container Service for Kubernetes to release application versions in batches, achieving fast version verification and rapid iteration of applications.

What to do next

You can use batch release to quickly verify your application version without traffic consumption. Batch release is more resource-saving than blue-green release. Currently, batch release can be performed on only web pages. The yaml file editing is to be opened later to support more complex operations.
