Fundamental information
| Product | Abbreviation in CAM | Console | Authorization by Tag | Authorization Granularity | IP Restriction |
|---|---|---|---|---|---|
| Auto Scaling | as | Supported | Supported | Resource level | Partially supported |
Note：
The authorization granularity of cloud products is divided into three levels: service level, operation level, and resource level, based on the degree of granularity.
- Service level: It defines whether a user has the permission to access the service as a whole. A user can have either full access or no access to the service. For the authorization granularity of cloud products at service level, the authorization of specific APIs are not supported.
- Operation level: It defines whether a user has the permission to call a specific API of the service. For example, granting an account read-only access to the CVM service is an authorization at the operation level.
- Resource level: It is the finest authorization granularity which defines whether a user has the permission to access specific resources. For example, granting an account read/write access to a specific CVM instance is an authorization at the resource level.
API authorization granularity
Two authorization granularity levels of API are supported: resource level, and operation level.
- Resource level: It supports the authorization of a specific resource.
- Operation level: It does not support the authorization of a specific resource. If the policy syntax restricts a specific resource during authorization, CAM will determine that this API is not within the scope of authorization, and deem it as unauthorized.
