Create security-enhanced instances

Create a security-enhanced instance in the ECS console

The procedure for creating a security-enhanced instance in the ECS console is similar to that for creating a non-security-enhanced instance. However, you must pay attention to specific options when you create a security-enhanced instance. This procedure describes the specific configurations to make when you create a security-enhanced instance. For information about other general configurations, see Create an instance by using the wizard.

1. Log on to the ECS console.
2. In the left-side navigation pane, choose Instances & Images > Instances.
3. Click Create Instance.
4. Configure the settings in the Basic Configurations step.
   Take note of the following parameters:

   • Instance Type: Select a security-enhanced instance type. For more information about security-enhanced instance types, see Instance families.
     Note The g7t, c7t, and r7t instance families support Software Guard Extensions (SGX) encrypted computing. When you create a g7t, c7t, or r7t instance in the ECS console, the Alibaba Cloud SGX runtime is automatically installed. For information about how to build an SGX encrypted computing environment on a g7t, c7t, or r7t instance, see Build an SGX encrypted computing environment.
   • Image: Select an image version based on the instance family. The following table describes the available image versions.

     Instance family	Image version
     g6t, c6t, and r6t	Alibaba Cloud Linux 2.1903 64-bit (Trusted) CentOS 7.8 64-bit (Trusted)
     g7t, c7t, and r7t	Alibaba Cloud Linux 2.1903 LTS 64-bit (UEFI) CentOS 8.4 64-bit (UEFI) CentOS 8.3 64-bit (UEFI) Ubuntu 20.04 64-bit (UEFI) Ubuntu 18.04 64-bit (UEFI)

     Note If you select Trusted System when you create an instance, the Alibaba Cloud trusted system is used for the instance. The Alibaba Cloud trusted system verifies the instance when the instance starts. If you want to use a self-managed trusted service system, do not select Trusted System.
5. Click Next: Networking. If the Enable Key Management Service (KMS) dialog box appears, click Enable.
   KMS must be activated. Otherwise, the security-enhanced instance cannot be created. If you have activated KMS, the dialog box does not appear. Proceed with the Networking step.
6. Click Next: System Configurations.
   If Trusted System is selected, you must specify a RAM role for the instance. The RAM role must be granted permissions to access the trusted services. Alibaba Cloud provides you with the corresponding AliyunECSInstanceForYundunSysTrustRole service-linked role. We recommend that you configure and select this role by performing the following steps.

   Note If you need more precise or customized configurations, create a role and grant it permissions based on your needs. When you create a RAM role, you must take some precautions. For more information, see Precautions on granting permissions to RAM roles.
   1. Click here to authorize.
      
   2. In the Cloud Resource Access Authorization dialog box, click Confirm Authorization.
   3. In the dialog box that appears, click Confirm Authorization Policy.
   4. Click Authorized.
      
   5. Select AliyunECSInstanceForYundunSysTrustRole as the RAM role.
      
   Note You can also skip the authorization step and grant permissions after the instance is created. For more information, see Bind an instance RAM role.
7. Follow the steps in the wizard to create the instance.
