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: Choose an availability zone within the selected region. Supports selecting a random availability zone, and the system will assign it randomly.
Instance Architecture: Supports single-node and two-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 a two-node architecture is chosen, the storage type supports selecting Enhanced SSD, Balanced SSD, and Premium Local SSD.
For a detailed understanding of each storage type's descriptions and use cases, see Storage Types.
Database Version: Supports SQL Server 2008 R2, SQL Server 2012, SQL Server 2014, SQL Server 2016, SQL Server 2017, SQL Server 2019 Enterprise and Standard Editions. Supports SQL Server 2022 Enterprise.
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.
Multiple Availability Zones Deployment: This option appears when selecting the two-node instance architecture. Choosing Yes indicates setting up deployment in multiple availability zones, and the next step involves selecting a standby availability zone. Choosing No indicates not proceeding with multiple availability zone deployment. Currently, only regions of Shanghai, Beijing, Guangzhou, and Hong Kong (China), support selecting multiple availability zones. Multiple availability zones combine several single availability zones within the same region into a physical zone. This can protect the database from instances of failure or availability zone interruptions.
Replica Availability Zone: After choosing multiple availability zones deployment, a standby availability zone must be selected. Specifics are subject to actual available resources.
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 or a two-node cloud disk instance, no application is needed. You can modify it directly.
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 or a two-node cloud disk instance, no application is needed. You can modify it directly.
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: When checked, and if your account balance is sufficient, based on the selected purchase duration, the device will monthly auto-renew after expiration.
Terms of Service: Read and agree to the corresponding terms of service.
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.
Yes
No
