Batch Compute service sends notification messages based on the topics offered by MNS. You can create, manage, and subscribe to topics, and specify topic configuration when using Batch Compute to create a cluster or submit a job. Batch Compute then pushes messages to the specified topics based on the configuration. You can set four notification methods in the MNS console: URL, MNS queue, email, and SMS. Currently, Batch Compute supports two types of message events: cluster events and job events.
Create an MNS topic
Create an MNS topic subscription

Log on to the console to complete one-key authorization. If you have not completed the authorization, the console displays the following message:
Skip this step if you have completed the authorization.
2. Billing
