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 period |
Data disks (optional) | If you mount a data disk to your simple application server, you must pay for the data disk based on its capacity. If you do not mount a data disk to your simple application server, this fee does not occur. Note Only enhanced SSDs (ESSDs) of performance level 0 (PL0) and standard SSDs can be used as data disks of simple application servers. The prices of disks of the same category may vary with regions. You can view the prices of disks in different regions on the Elastic Block Storage Price tab of the Elastic Block Storage Pricing page. The prices of disks of the same category may vary with regions. You can go to the Pricing tab of the Elastic Compute Service 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 period |
Excess data transfers (optional) | A plan contains a monthly data transfer quota. After the data transfer quota is used up, you are charged for the excess data transfers based on the pay-as-you-go billing method. For information about the unit price of excess data transfers, see Simple Application Server Pricing. 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 instances, 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 of 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 from a snapshot of a simple application server. You can use custom images 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 of 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 to ECS. If a shared image is created from an application image, whether you are charged for using the shared image depends on the billing method of ECS instances created by 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). These 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. 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 | Description | Price |
Example 1: Plan price + Data disk price | The following resources are used to create a simple application server in the following region:
| 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 based on 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 to the Internet after the data transfer quota in the plan is used up.
| 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 based on the following formula: |
