Confirm the configuration info. Then, read and indicate your consent to the Terms of Service, confirm that everything is correct, and click Buy Now.
Step 1. Select a basic configuration
In this step, you can set the basic configuration and specification options for the instance. The specific settings are as follows:
Basic Configuration
Billing Mode: Pay-as-you-go.
Region: We recommend that you choose the region closest to your end users to minimize access latency and improve download speed.
AZ: Select an AZ in the selected region. You can also use the AZ that is randomly allocated by the system.
Instance architecture: Support single-node, dual-node, and multi-node.
Storage Type:
When single-node architecture is selected, you can choose from premium cloud disk, SSD, balanced SSD, and enhanced SSD.
Note:
In the Chinese mainland, if you need SSD for your basic edition instances, submit a ticket for application.
When two-node architecture is selected, you can choose from enhanced SSD, balanced SSD, and high-performance local SSD.
For multi-node architecture, available storage types include Enhanced SSD and Balanced SSD.
For a detailed description of each storage type and applicable scenarios, see Storage Types.
Database Version: supports SQL Server 2008 R2, SQL Server 2012, SQL Server 2014, SQL Server 2016, SQL Server 2017 and SQL Server 2019 Enterprise and Standard version as well as SQL 2022 Enterprise version. The supported database versions vary by instance architecture. See the purchase page for details.
Number of Replica Nodes: If multi-node architecture is selected, you need to specify the number of replica nodes from 2 to 5. The settings is not required for single-node or dual-node architectures.
Multi-AZ Deployment: This option is available when a dual-node or multi-node architecture is selected. For multi-node architecture, it can only be set to enabled.
Enabled: Multi-AZ Deployment is enabled, requiring the selection of secondary AZs in the next step. Each secondary node can be assigned a secondary AZ. Note: If all secondary nodes are deployed in the same AZ, the AZ-level disaster recovery is not supported. Please choose different secondary AZs.
Disabled: Multi-AZ Deployment is not enabled. Currently, only Shanghai, Beijing, Guangzhou, and Hong Kong (China) support multi-AZ deployment. Multi-AZ is a physical zone that combines multiple single AZs in the same region, which is used to protect databases in case of instance faults or AZ interruptions.
Replica AZ: If multi-AZ deployment is enabled, select the replica AZ based on the available resources.
Specs Configuration
Type: The Dedicated type is supported.
Filter: You can quickly filter the needed CPU and memory specifications for the instance. By default, all CPU and memory specifications are selected.
Selected instances: The specification information of the selected instances are displayed, including specification type and specification.
Instance Specifications: The detailed specification information is displayed, including the specification type, CPU, memory, maximum IOPS, supported AZs, and reference fees.
Storage Space: Select the required disk capacity.
Step 2. Set network and database
Network: VPC is supported. For connectivity testing, see Network Environment. Both VPCs and subnets support fuzzy search.
Note:
We recommend that you place the CVM and TencentDB instances under the same account in the same VPC in the same region.
A subnet is a logical network space in a VPC. You can create subnets in different AZs in the same VPC, which communicate with each other over the private network by default. Even if you select a subnet in another AZ in the same region, the network latency will not be increased because the actual business connection adopts nearby access.
Security Group: A security group is a stateful virtual firewall capable of filtering. As an important means for network security isolation provided by Tencent Cloud, it can be used to set network access controls for one or more TencentDB instances.
Note:
You can either create new security groups or choose from existing ones. You can also locate the target group by fuzzy search.
Instance Name: Select Set After Creation or Set Now.
System Time Zone: China Standard Time (Beijing Time) is supported by default.
For the purchase of the two-node local disk instances, submit a ticket to apply for the modification of the system time zone.
If you purchase a single-node, dual-node, or multi-node cloud disk instance, modification can be performed directly.
Sorting Rules of Character Set: The instance character set provides sorting rules for system data, namely, distinguishing between case-sensitive attributes and accent attributes. The Chinese_PRC_CI_AS is supported by default.
If a two-node local disk instance is purchased, submit a ticket to apply for the modification of the rules for the character set.
If you purchase a single-node, dual-node, or multi-node cloud disk instance, modification can be performed directly.
Project: TencentDB for SQL Server supports assigning instances to different projects for management. You can perform fuzzy search for projects by name.
Tag: You can use tags to easily categorize and manage resources. You are allowed to add multiple tags.
Maintenance Window/Maintenance Time: The backend system performs maintenance operations on your TencentDB for SQL Server instance from time to time to ensure its stability. To minimize the potential impact on your business, we recommend that you set an acceptable maintenance period for your business instance, usually during off-peak hours. You can select up to all the seven options for the maintenance windows.
Step 3. Confirm the configuration info
Display the configuration details of instances in step one and step two. If modifications are needed, click Edit. After all settings are confirmed, enable auto-renewal, read and agree to terms of the service, and click Purchase Now.
Auto-renewal (for monthly subscription billing mode): If auto-renewal is enabled and the account balance is sufficient, the instance will be automatically renewed upon expiration based on the selected purchase duration: monthly or annually.
Purchase duration of 1 to 11 months: The auto-renewal period is one month, and the instance will be automatically renewed on a monthly basis upon expiration.
Purchase duration of 1 to 5 years: The auto-renewal period is one year, and the instance will be automatically renewed on a yearly basis upon expiration, with an auto-renewal discount applied.
After the purchase is completed, return to the Instance List and view the created instance. Once the status changes to Running, the instance is created successfully.
Creating an account
1. In the instance list, click an instance ID or Manage in the Operation column to enter the instance management page.
2. On the instance management page, select Account Management > Create Account and enter relevant information in the pop-up window. After confirming that everything is correct, click OK.
Note:
The created account name and password will be used when connecting to TencentDB for SQL Server. Store them properly.
Creating a database
1. In the instance list, click an instance ID or Manage in the Operation column to enter the instance management page.
2. On the Instance Management page, select Database Management > Create Database, set configuration items in the pop-up window, confirm that everything is correct, and click OK.
Database Name: It can contain up to 32 letters, digits, and underscores and must start with a letter.
Character Set: Select the character set to be used by the database. Currently, most native character sets are supported.
