Process

• A user sends comments to Alibaba Cloud Kafka through the web service

• The Kafka Source monitors comments from the event source and sends the comments to the comment processing service.

• The processing service receives the comments, scales the instance to process comments automatically, and sends the processed comments to the bullet-screen comments service.

• Finally, the bullet-screen comments are displayed to users through the web service interface.

Summary

Some capabilities brought by Knative on Alibaba Cloud are listed below:

• Easy service deployment

• Serverless-based, on-demand resource usage

• Seamless integration of Eventing with Alibaba Cloud products for message delivery

• Native integration with Alibaba Cloud Kubernetes ecosystem

• Integration with Alibaba Cloud's products

Hopefully, these capabilities can bring real on-demand use experience to users and reduce the cost of O&M and resource use, which is also the goal pursued by Serverless.
