Resource-based Service Roles
Overview
A role is a virtual identity with an array of permissions. It serves to grant permissions of access to services, operations, and resources within Tencent Cloud to a role carrier. You can associate roles with cloud resources, allowing them to access other cloud product APIs based on Tencent Cloud Security Credential Service STS temporary keys (which can be periodically updated). Compared with direct control via persistent keys, this method further ensures the security of persistent keys under the account and allows more refined control and permission management via role association policies.
Advantages
After a CAM role is bound to cloud resources, the following features and advantages are bestowed:
Access Tencent Cloud's other cloud services through STS temporary keys. For more details, please refer to AssumeRole.
Assign roles with varying access policies to different resources, enabling differentiated access privileges across different cloud services, hence advocating precision granularity in permission control.
Be free from manually saving persistent keys within instances. Access rights can be swiftly altered and maintained by modifying the role's authorization.
