Prerequisites
To purchase instances, you need to verify your identity first. For more information, see Identity Verification Guide.
Purchasing at the Official Website
1. Go to the TencentDB for SQL Server purchase page, complete the following steps in sequence, including choose basic configuration , set network and database , confirm configuration information, read and indicate your consent to the Terms of Service, confirm that everything is correct, and click Buy Now.
Step 1: Choose basic configuration
In the step of choosing the basic configuration, you can set the basic and specification configuration items of the instance. The specific settings are as follows.
Basic Configuration
Billing Mode: Supports monthly subscription and pay-as-you-go.
Region: Choose the region for instance deployment. To minimize access latency and improve download speed, we recommend selecting the region closest to your customers.
Availability Zone: Select an AZ within the selected region.
Instance Architecture: Support single-node, two-node, and multi-node.
Storage Type:
When a single-node architecture is chosen, the storage type supports selecting Premium Cloud Disk, SSD, Balanced SSD, and Enhanced SSD.
Note:
In domestic regions, for single node instances that require SSD CBS disk types, Submit Ticket for application.
When the two-node architecture is selected, the storage type supports Enhanced SSD, Balanced SSD, and High-Performance Local SSD.
When the multi-node architecture is selected, the storage type supports Enhanced SSD and Balanced SSD.
For details of each storage type and use cases, see Storage Types.
Database Versions: Support SQL Server 2008 R2, SQL Server 2012, SQL Server 2014, SQL Server 2016, SQL Server 2017, SQL Server 2019 Enterprise/Standard, and SQL Server 2022 Enterprise. You can view database versions supported for different instance architectures on the purchase page.
Disk encryption: For instances located in Shanghai, with storage type of Cloud Block Storage (CBS) and database version of SQL Server 2019/2022 Enterprise, the disk encryption feature can be used after applying for whitelisting. This feature is not supported in other regions or for other versions. If you need to use this feature, submit a ticket for application. The disk encryption field will only be displayed after you apply for disk encryption.
Key source: This item is displayed when disk encryption is enabled. Currently, the default key source is provided by Tencent Cloud.
Number of replica nodes: If the multi-node architecture is selected, you need to specify the number of replica nodes with the number range from 2 to 5. The settings are not required for single-node or two-node architecture.
Multi-AZ deployment: This option is available when a two-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.
Secondary AZ: If multi-AZ deployment is enabled, select the secondary AZs based on the available resources.
Specification Configuration
Type: Supports dedicated type.
Filter: Quickly filter the needed CPU and memory for the instance. All CPU and memory selected by default.
Selected Instances: Displays the specification information of selected instances, including specification type and specifications.
Instance Specification: Displays the instance's specification type, CPU, and memory. Supports availability zone, and specification reference fees.
Storage Space: Selects the required disk capacity.
Step 2: Set network and database
Network: Supports VPC. For connectivity testing, see Network Environment. VPC networks and subnets support fuzzy search.
Note:
We recommend having cloud services and TencentDB in the same account, and within the same VPC (ensuring the same region, without limiting the availability zone).
A subnet is a network space within a VPC and is a logical concept. In the same VPC, you can create subnets in different availability zones. Subnets in different availability zones of the same VPC can communicate with each other over the private network by default. Even if you choose a subnet in a different availability zone but in the same region, the actual business connection access follows a nearby logic and will not increase network latency.
Security Group: A stateful virtual firewall that includes a filtering feature, used for setting network access control for single or multiple TencentDB instances. It is an important means of network security isolation provided by Tencent Cloud.
Note:
Supports creating a new security group or selecting an existing one. Supports for multiple selection and fuzzy search.
Instance Name: Supports immediate naming of the instance or renaming after creation.
System Time Zone: Supports for China Standard Time (Beijing Time) by default.
If you purchase a two-node local disk instance and want to modify the system time zone, you must first Submit Ticket for application.
If you purchase a single-node cloud disk, a two-node cloud disk, or a multi-node cloud disk instance, you can directly modify the system time zone on the purchase page with no need for an application.
Character Set Sorting Rules: The instance character set provides sorting rules for system data, i.e., case sensitivity and accent attributes. Default support is provided for Chinese_PRC_CI_AS.
If you purchase a two-node local disk instance and want to modify the character set rules, you must first Submit Ticket for application.
If you purchase a single-node cloud disk, two-node cloud disk, or multi-node cloud disk instance, you can directly modify the character set collation on the purchase page with no need for application.
Belonging Project: TencentDB for SQL Server supports assigning instances to different projects for management. Supports fuzzy search for project names to quickly select projects.
Tag: Facilitates categorization and management of instance resources. Supports adding multiple tags.
Maintenance Cycle and Maintenance Time: To ensure the stability of your TencentDB for SQL Server instance, the backend system performs maintenance operations on the instance during maintenance time from time to time. It is recommended to set an acceptable maintenance time for your business instance. To minimize the impact on your business, it is typically scheduled during off-peak hours. The maintenance cycle supports choosing up to 7 periods.
Step 3: Confirm configuration information
Display the configuration details of Step 1 and Step 2. If modifications are needed, you can directly click Edit . After confirming the details are correct, complete setting up auto-renewal. Read and check the service terms, and then click Buy 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.
Terms of service: Cloud database service terms, Service level agreement, and Refund instruction.
2. After the purchase is made, return to the instance list and view the created instance. When the instance status becomes Running, the instance is successfully created.
