Billing Items

The price of an MRS cluster consists of two parts:

• MRS management fee
• Fees of IaaS infrastructure resources, including Elastic Cloud Server (ECS), Elastic Volume Service (EVS), elastic IP (EIP), and bandwidth

For details about the MRS management fee, see Product Pricing Details. You can use the price calculator of MRS to quickly obtain an estimate price of a cluster with the specifications you select.

The terminated or unsubscribed MRS cluster is no longer billed.

Billing Modes

Before using MRS, you must purchase an MRS cluster. Currently, MRS provides two billing modes:

• Yearly/Monthly: You can pay for clusters by year or month. The minimum duration is 1 month and the maximum duration is 1 year.
• Pay-per-use: Nodes are billed by actual duration of use, with a billing cycle of one hour.

Changing Billing Mode

Before subscribing to MRS, choose Master and Core node instances that best fit your needs. MRS provides the following methods for you to change cluster configuration after a cluster is started.

• Configure Task Node: Add Task nodes. For details, see Related Operations in Manually Scaling Out a Cluster.
• Scale Out: Manually add Core or Task nodes. For details, see Manually Scaling Out a Cluster.
• Scale Up Specifications: Upgrade the instance specifications of the Master node. For details, see Scaling Up Master Node Specifications.
• Auto Scaling: The number of nodes in a cluster can be automatically adjusted based on the service data volume to increase or decrease resources. For details, see Using Auto Scaling in a Cluster.

If the configuration change methods provided by MRS do not meet your requirements, you can create a cluster again and migrate data to the cluster to realize cluster configuration change.

Renewal

To renew the subscription, go to the Renewals page.

Overdue Payment

Overdue payment does not apply to yearly or monthly subscribed clusters.

In pay-per-use mode, cluster fees are deducted every hour. If your account balance is insufficient to pay for the expense occurred in the last hour, your account will be in arrears, and MRS clusters have a retention period. If the clusters are renewed within the retention period, they will be available and charged from the original expiration date.

Expiration

• Expiration does not apply to pay-per-use clusters.
• If your yearly or monthly subscription expires, the cluster will enter into a retention period. During the grace period and retention period, you cannot perform operations on the cluster on the MRS management console, related APIs cannot be called, and O&M operations such as automatic monitoring and alarm reporting will be stopped. If your subscription is not renewed at the end of the retention period, services in the cluster will be terminated and data in the system will be deleted permanently.
