Elastic Compute Service:Create a Super Computing Cluster (SCC) instance

Procedure

1. Go to the instance buy page.

2. Configure parameters such as the billing method, instance type, and image.

   Parameter	Description
   Billing Method	Defines how you pay for an instance. This choice also affects the instance lifecycle rules. Valid values: Subscription pay-as-you-go Spot Instance
   Region	A region is a geographical area where data centers are located. Selecting a region close to your users reduces network latency. You cannot change the region of an instance after it is created. For more information, see Regions and zones.
   Network and Zone	Use a Virtual Private Cloud (VPC). VPCs are logically isolated from each other to improve security. They also support features such as elastic IP addresses (EIPs), elastic network interfaces (ENIs), and IPv6. A zone is a physical area within a region with independent power and network infrastructure. Instances in the same zone have lower network latency, which provides faster access for users.
   Instance	In the Architecture row, select High-performance Computing and then Super Computing Clusters. Then, select an SCC instance type. The available instance types vary based on factors such as the region. To check instance availability, see Available ECS instance types by region. For more information about SCC instance types, see instance families. After you select an SCC instance type, in the Super Computing Clusters section, do one of the following: On the Existing Cluster tab, select an existing Super Computing Cluster to scale it out, or on the New Cluster tab, enter a name and description to create a new cluster. Important Instances in different clusters cannot communicate with each other. Choose the cluster ID carefully. If you are unsure which cluster to use, go to the Super Computing Cluster page, select a cluster, and then add instances to scale it out.
   Images	An image provides the information required to run an instance. Alibaba Cloud provides multiple image sources. Available images are displayed on the page.

3. Configure other parameters for storage, bandwidth, security groups, and management settings.

   For detailed descriptions of the parameters, see Parameter description.

4. Before you create the instance, review the overall configuration in the pane on the right, configure options such as the subscription duration, and verify your settings.

5. Read and select ECS Service Terms and Refund Policies and Procedure, and then click Confirm Order.

   Note

   You need to read and confirm the Refund Policies and Procedure only when you purchase subscription instances.

   Instance creation takes 3 to 5 minutes. Go to the instance list page in the ECS console to view the instance status. The instance is successfully created when its status changes to Running.
