Permissions

ELB Permissions

New IAM users do not have any permissions assigned by default. You need to first add them to one or more groups and attach policies or roles to these groups. The users then inherit permissions from the groups and can perform specified operations on cloud services based on the permissions they have been assigned.

ELB is a project-level service deployed for specific regions. To assign ELB permissions to a user group, specify the scope as region-specific projects and select projects for which you want the permissions to take effect. If you select All projects, the permissions will take effect for the user group in all region-specific projects. When accessing ELB, users need to switch to the authorized region.

You can grant permissions by using roles and policies.

• Roles: A coarse-grained authorization strategy provided by IAM to assign permissions based on users' job responsibilities. Only a limited number of service-level roles are available for authorization. When you grant permissions using roles, you also need to attach any existing role dependencies. Roles are not ideal for fine-grained authorization and least privilege access.
• Policies: A fine-grained authorization strategy provided by IAM to assign permissions required to perform operations on specific cloud resources under certain conditions. This type of authorization is more flexible and is ideal for least privilege access. For example, you can grant ELB users only permissions to manage a certain type of resources. A majority of fine-grained policies contain permissions for specific APIs, and permissions are defined using API actions. For the API actions supported by ELB, see Elastic Load Balance API Reference.

Table 2 describes common operations supported by each system policy of ELB.
