Billing Scenario

Assume that a user purchased a pay-per-use MRS analysis cluster of the normal edition at 15:30:00 on March 18, 2023 and the configurations were as follows:

• master_node_default_group node group (Master node group for short)
  • Number of nodes: 3
  • Node specifications: c6.2xlarge.2 (8 vCPUs and 16 GB)
  • System disk: ultra-high I/O and 480 GB
  • Data disk: ultra-high I/O and 600 GB
• core_node_analysis_group node group (Core node group for short)
  • Number of nodes: 3
  • Node specifications: c6.xlarge.4 (4 vCPUs and 16 GB)
  • System disk: general-purpose SSD and 480 GB
  • Data disk: general-purpose SSD and 600 GB

After a period of time, the user found that the current specifications of the MRS cluster could not meet service requirements and added a node to the core_node_analysis_group node group at 09:00:00 on March 20, 2023. However, the memory of the master_node_default_group node group was insufficient for supporting the sustainable growth of services. At 10:00:00 on March 20, 2023, the user upgraded the specifications of the Master node to c6.2xlarge.4 (8 vCPUs and 32 GB). Since the cluster was intended for long-term use, the billing mode was switched to yearly/monthly on March 20, 2023, 11:00:00, and the billing period is for one month. How much is the total fee of the MRS instance in March and April?

Billing Analysis

The usage of the MRS instance can be divided into two phases based on the billing mode: pay-per-use from March 18, 2023, 15:30:00 to March 20, 2023, 11:00:00, and yearly/monthly from March 20, 2023, 11:00:00 to April 20, 2023, 23:59:59.

Pay-per-use billing

From March 18, 2023, 15:30:00 to March 20, 2023, 09:00:00, the billing is based on the cluster specifications used during cluster creation for 41.5 hours. The fees are calculated as follows.

If one node is added to the Core node group from 9:00:00 to 10:00:00 on March 20, 2023 for one hour, the fee is calculated as follows.

If the specifications of the Master node group are upgraded to c6.2xlarge.4 (8 vCPUs and 32 GB) for one hour from 10:00:00 to 11:00:00 on March 20, 2023. The fee is calculated as follows.

Yearly/Monthly billing

From March 20, 2023, 11:00:00 to April 20, 2023, 23:59:59, the billing mode is yearly/monthly, and the billing period is for one month. The fees are calculated as follows.

From March to April, the total price of this ECS is $2903.6 USD (176.25 + 4.83 + 5.08 + 2717.44).
