Purchasing at the Official Website
1. Go to the TencentDB for SQL Server purchase page, select the desired database configuration, read and indicate your consent to the Terms of Service, confirm that everything is correct, and click Buy Now.
Network: VPC (recommended) and the classic network are supported. For more information on their differences and connectivity testing, see Network Environment. Both VPCs and subnets support fuzzy search.
Note:
We recommend 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.
As the classic network resources become increasingly scarce and cannot be expanded, Tencent Cloud accounts registered after June 13, 2017 can create instances (including CVM and TencentDB) only in a VPC rather than the classic network.
Instance Type: Dual-Server High-Availability Edition, Cluster Edition, and Basic Edition are supported.
Note:
The Cluster Edition currently supports SQL Server 2017 Enterprise and SQL Server 2019 Enterprise, which use the Always On technology to build SQL Server clusters with high performance, availability, reliability, and ease of maintenance.
Disk Type: High-performance local SSD, high-performance cloud disk, and SSD cloud disk are supported.
Note:
In the Chinese mainland, if you need SSD cloud disks for your Basic Edition instances, submit a ticket for application.
Disk Type
Description
Suitable Database Architecture
Applicable Scenario
High-performance local SSD
High-I/O local disk storage type.
High-Availability Edition/Cluster Edition
Business scenarios that have extremely high requirements for storage I/O performance and high-availability architecture at the application layer, such as online games, ecommerce, ERP software services, video live streaming, and media.
Premium cloud disk
Hybrid storage type. It provides high-performance storage capabilities close to SSD through the cache mechanism and adopts a three-copy distributed mechanism to ensure the data reliability.
Basic Edition
Small and medium application scenarios that require high data reliability and moderate performance, such as web/app servers, business logic processing, and small and medium websites.
SSD cloud disk
All-flash cloud disk storage type with NVMe SSD as the storage media. It adopts a three-copy distributed storage mechanism to provide low-latency and high-throughput I/O capabilities with a high random IOPS and 99.9999999% (nine nines) data security.
Basic Edition
Application scenarios such as I/O-intensive applications and small and medium relational databases.
Database Version: The Enterprise and Standard Editions of SQL Server 2008 R2, SQL Server 2012, SQL Server 2016, SQL Server 2017, and SQL Server 2019 are supported. Each AZ supports different database versions.
Select an instance specification and required disk capacity.
Multi-AZ: Currently, only Shanghai, Beijing, Guangzhou, and Hong Kong (China) regions support selecting multi-AZ. By combining multiple AZs into a single "multi-AZ", the multi-AZ deployment mode protects databases from database instance failures and AZ outage.
Maintenance Window and Maintenance Time: To ensure the stability of your TencentDB for SQL Server instance, the backend system performs maintenance operations on the instance during the maintenance window from time to time. We highly recommend you set an acceptable maintenance time for your business instance, usually during off-peak hours, so as to minimize the potential impact on your business.
Project List: TencentDB for SQL Server supports assigning instances to different projects for management. You can fuzzy search for projects by name.
Security Group: It serves as a stateful virtual firewall with filtering feature for configuring network access control for one or more TencentDB instances. It is an important network security isolation tool provided by Tencent Cloud.
Tag: Categorize and manage resources with tags.
System Time Zone: By default, only China Standard Time is supported. To change it, submit a ticket for assistance.
Character Set Collation: The instance's character set provides a collation for system data, i.e., the case sensitivity and accent sensitivity attributes. By default, only Chinese_PRC_CI_AS is supported. To adjust it, submit a ticket for assistance.
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.
