This topic describes the billable items of Simple Application Server and provides billing examples of the service.
Billable items
Simple application server
The prices in this topic are provided only for reference. The prices that are displayed on the buy page of simple application servers take precedence.
Billable item | Description | Billing method | Billing rule |
Plan specifications | The combination of computing resources, storage resources, and network resources. For more information about plans, see Pricing of resource plans. | Subscription | Price of plan specifications × Subscription duration |
Data disks (optional) | If you attach a data disk to your simple application server, you must pay for the data disk based on the capacity of the disk. If you do not attach a data disk to your simple application server, you are not charged the disk capacity fee. The prices of disks of the same category may vary based on the region. You can go to the Pricing tab of the Elastic Compute Service (ECS) product page and click the Storage tab to view the prices of disks in different regions. | Subscription | Unit price of data disks × Capacity of the data disk × Subscription duration |
Excess data transfers (optional) | After the data transfer quota in your plan is exhausted, you are charged for excess data transfers on a pay-as-you-go basis.
The unit price for excess data transfers:
Note
| Pay-as-you-go | Unit price of data transfers × Excess data transfers |
Snapshots | A snapshot is a point-in-time backup of a disk. Snapshots can be used to back up data, recover data after accidental operations on servers, recover data after network attacks, and create custom images. Note You are not charged for creating snapshots. The maximum number of snapshots that can be retained in an Alibaba Cloud account is triple the number of simple application servers that you have. The value cannot be greater than 15. | Free of charge | None |
Custom images | A custom image is created based on a snapshot of a simple application server. You can use a custom image to create multiple simple application servers that have the same configurations. You can also share custom images with ECS and use the shared images to create ECS instances or replace the OSs of existing ECS instances. Important You are not charged for creating custom images. The maximum number of custom images that can be retained in an Alibaba Cloud account is triple the number of simple application servers that you have. The value cannot be greater than 15. | Free of charge | None |
Shared images | You can share a custom image created in Simple Application Server with ECS. If a shared image is created based on an application image, the billing method of ECS instances created by using the shared image determines whether you are charged for using the shared image.
| Subscription | Image price = Unit price of the image × Subscription duration.
|
Service interconnection | By default, simple application servers that belong to the same Alibaba Cloud account and region are deployed in the same virtual private cloud (VPC). The servers can communicate with each other over the VPC free of charge. Important If you want simple application servers that belong to different Alibaba Cloud accounts or regions to be interconnected, go to the Cloud Enterprise Network (CEN) console to configure relevant settings. You are charged for service interconnection across Alibaba Cloud accounts or regions. For more information, see Billing rules. | Free of charge | None |
Billing examples
The following table describes how to calculate the price of using a simple application server in different scenarios.
Example | Scenario | Price |
Example 1: Plan price + Data disk price | You select the following region and resources to create a simple application server:
| Total price = Plan price × Subscription duration + Data disk price × Subscription duration Data disk price = Unit price of data disks × Data disk capacity (GB) In this example, the total configuration price of the simple application server is USD 21.72, which is calculated by using the following formula: |
Example 2: Price of excess data transfers | A simple application server that is deployed in the China (Hong Kong) region transfers additional 8 GB of data over the Internet after the data transfer quota in the plan is exhausted.
| Price of excess data transfers = Unit price of data transfers × Excess data transfers. In this example, the price of excess data transfers is USD 1.224, which is calculated by using the following formula: |
