Billing You can use AS for free, but ECS instances automatically created in an AS group are billed on a pay-per-use basis. For pricing details, see ECS Billing. EIPs used by the instances are also billed. For pricing details, see EIP Billing.
Data Protection User encryption allows you to use the encryption feature provided on the cloud platform to encrypt ECS resources, improving data security. If you use an encrypted ECS to create an AS configuration, the AS configuration is encrypted as the ECS.
Managing Lifecycle Hooks Lifecycle hooks enable you to flexibly control addition and removal of ECS instances in AS groups and manage the lifecycle of ECS instances in AS groups. Figure 1 shows the instance lifecycle when no lifecycle hook is added to an AS group.
AS Introduction Auto Scaling (AS) helps you automatically scale Elastic Cloud Server (ECS) and bandwidth resources to keep up with changes in demand based on pre-configured AS policies.

Currently, AS can automatically scale up or down bandwidths, and scale in or out ECS instances in an AS group. Parent topic: General

The expected number of instances refers to the number of ECS instances that are expected to run in an AS group. It is between the minimum number of instances and the maximum number of instances.

AS Configuration An AS configuration is a template specifying specifications for the ECS instances to be added to an AS group. The specifications include the ECS type, vCPUs, memory, image, login mode, and disk.
Then, all ECS instances are removed from the AS group and the AS group is deleted. Note that the manually added ECS instances will be removed from the AS group and the ECS instances automatically created by AS will be automatically deleted.
Setting Monitoring Alarm Rules Scenarios Setting alarm rules allows you to customize the monitored objects and notification policies and determine the running status of your ECS instances at any time. Procedure Log in to the management console.
ECS instances in an AS group can be released automatically by AS, so they cannot be used to save application status information (such as session statuses) or related data (such as database data and logs).

On the Copy AS Configuration page, modify parameter settings, such as Name, Specifications, and Image, and configure the ECS login mode (key pair) based on service requirements. Click OK. Parent topic: AS Configuration
An instance is an ECS in an AS group.
Possible cause: The ECS type in the AS configuration does not match the image, leading to the ECS creation failure. Handling method: Change the AS configuration for the AS group and then enable the AS group.

Viewing Monitoring Metrics Scenarios The cloud platform provides Cloud Eye to help you obtain the running status of your ECS instances. This section describes how to view details of AS group metrics to obtain information about the status of the ECS instances in the AS group.
Changing the AS Configuration for an AS Group Scenarios If you need to change the specifications of ECS instances in an AS group, changing the AS configuration used by the AS group is an easy way to help you get there.
