Billing Items
1. Instance Type
The billing of Elastic Compute Service (ECS) instance types refers to the billing of computing resources (vCPUs and memory). Instances are billed based on instance type, including vCPUs and memory. Prices of an instance type may vary with specification.
| Billing Method | Description |
|---|---|
| Subscription | Price = Unit price of an instance type × Subscription duration. |
| Pay-as-you-go | Price = Unit price of an instance type × Billing duration. |
2. System Disk
The system disk type includes Ultra Disk and Standard SSD.
You are charged for system disks based on their unit price, capacity, and use duration.
| Billing Method | Description |
|---|---|
| Subscription | Price = Cloud disk capacity × Unit price of a disk × Subscription duration |
| Pay-as-you-go | Price = Cloud disk capacity × Unit price of a disk × Billing duration |
The billing methods of system disks depend on how the disks are created.
- System disks that are created along with an Elastic Compute Service (ECS) instance use the same billing method as the ECS instance.
- System disk cannot be separately created.
- System disk needs to be created, renewed, and released with ECS instance.
3. Snapshot
A snapshot is a backup file that captures the point-in-time status of disks. Snapshots are used for disaster recovery and environment cloning.
You are charged based on the size and storage duration of all snapshots. By default, the pay-as-you-go billing method is used. You are charged for a snapshot from the time when it is created to the time when it is released.
Snapshots have disaster recovery capabilities and are stored in Object Storage Service (OSS) buckets that are in the same region as the snapshots.
4. Data Disk
The data disk type includes Ultra Disk and Standard SSD.
You are charged for cloud disks based on their unit price, capacity, and use duration.
| Billing Method | Description |
|---|---|
| Subscription | Price = Cloud disk capacity × Unit price of a disk × Subscription duration |
| Pay-as-you-go | Price = Cloud disk capacity × Unit price of a disk × Billing duration |
The billing methods of cloud disks depend on how the disks are created.
- Data disks that are created along with an Elastic Compute Service (ECS) instance use the same billing method as the ECS instance.
- Data disk can be separately created.
