Limits

• The use of OOS extensions is subject to the following limits. The ECS instance status, Cloud Assistant client, and operating system must meet specific conditions:

  • The ECS instance must be in the Running state.

  • The Cloud Assistant agent is installed on the ECS instance and has a status of Normal.

  • Supported operating systems include Alibaba Cloud Linux, CentOS, Ubuntu, Debian, Fedora, and Windows Server. The operating systems that are supported by a specific extension are displayed in the console.

  • You can install or uninstall application performance acceleration only on the product pages of Yitian instances (g8y, c8y, and r8y).

• Permissions

  To use the OOS extension feature, you must have the AliyunECSExtensionsFullAccess system policy. An Alibaba Cloud account has this permission by default. If you are using a Resource Access Management (RAM) user, contact the Alibaba Cloud account owner to grant this permission to the RAM user. For more information about how to grant permissions, see Manage RAM user permissions.
