Configuration Item | Description |
Region | The physical data center where the instance is deployed. Each region is an independent data center, and the private networks of cloud services are not interconnected across different regions. Note: The region cannot be changed after the instance is created. Please choose carefully. For supported regions available for purchase, see Billing Overview. |
Instance Name | Set an instance name to distinguish between instances for different purposes. |
Billing Mode | Supports pay-as-you-go and yearly/monthly subscription billing modes. |
Instance Network | Select a virtual private cloud (VPC) in the corresponding region. If none exists, click Create VPC to create one. |
Availability Zone and Subnet | Select the availability zone and subnet for instance deployment. Note: The availability zone cannot be changed after the instance is created. Please choose carefully. |
Service Access Settings | Private network LB access: After it is enabled, a private network CLB is automatically created to provide a private network access endpoint, which can be accessed by other resources in the VPC where the cluster resides. The TCP/UDP protocols are supported. Services that need to be accessed by other clusters, CVMs, and other resources within the same VPC can use VPC private network access. Public network LB access: After it is enabled, a public network CLB is automatically created to provide an Internet access endpoint. The TCP/UDP protocols are supported. For example, you can enable public network access for TCBase WebUI access. After it is enabled, the risk of security group port intrusion increases. Enable it with caution. |
Security Group | Security groups feature firewall capabilities to configure network access controls for Cloud Virtual Machines (CVMs). If the number of security groups has reached the upper limit and new ones cannot be created, you can delete unused security groups. |
Computing Unit Architecture | Select the computing unit architecture. The default is primary/replica mode. |
Instance Specifications | Select the appropriate instance specifications. |
Storage Type | Select the storage type. Standard cloud storage and performance cloud storage are supported. |
Storage Space | The storage space per node is 100 GB by default and can be adjusted in multiples of 100 GB. |
User Information | Set the username and password for TCBase WebUI and database login. You can modify the password in the console after the instance is created. |
Tag | Tencent Cloud tags can be used to distinguish between different instance uses or for cost allocation by tag. |
Purchase Duration | Select the duration for purchasing a monthly subscription instance. |
Auto-renewal | Optional. The system will check daily whether the available balance in the user account is sufficient 7 days before the cluster expires and renew the cluster resources with automatic renewal enabled. For yearly/monthly subscription clusters, automatic renewal is selected by default, and users can manually deselect it. |
