Product Type

Scenario

Community-compatible Edition Subscription

Create a Community-compatible Edition cluster that uses the subscription billing method.

The subscription billing method allows you to use resources only after you pay for them. You complete the payment when you purchase a cluster. For long-term usage, this billing method is more cost-effective than the pay-as-you-go billing method. You are charged lower prices for longer subscription periods.

Enterprise Edition Serverless & Community-compatible Edition Pay-as-you-go

Create a Community-compatible Edition cluster or an Enterprise Edition cluster that uses the pay-as-you-go billing method.

The pay-as-you-go billing method allows you to use resources before you pay for them. The system generates a bill per hour and deducts the fee from the balance of your Alibaba Cloud account based on the cluster specifications. This billing method is cost-effective for business scenarios that require access to resources for short periods of time, such as testing. You can release a cluster based on your business requirements to save costs. When you can estimate the amount of resources that you need each month or each year, you can change the billing method from pay-as-you-go to subscription.
