If you purchase an Alibaba Cloud Elasticsearch cluster and other personnel (such as O&M, development, or data analytics personnel) in your organization want to use RAM users to access the cluster, you can attach policies to the RAM users based on the features that are required by the personnel. This improves system security and availability. You can also create multiple user groups and attach different policies to the user groups. This way, you can manage user permissions by user group.

Background information

RAM is a resource access control service provided by Alibaba Cloud. For more information, see What is RAM?

Policy description

Policies are categorized into system policies and custom policies.
  • System policies
    System policy Description
    AliyunElasticsearchReadOnlyAccess The read-only permissions on Elasticsearch or Logstash clusters. You can attach this policy to users to whom you want to grant only read-only permissions.
    AliyunElasticsearchFullAccess The management permissions on Elasticsearch clusters, Logstash clusters, or Beats shippers. After you attach this policy to a user, the user becomes an administrator.
  • Custom policies

    If system policies do not meet your business requirements, you can create custom policies. For more information, see Create a custom policy.

Prerequisites
