This document describes how to create a TDSQL Boundless Serverless instance through the console.

Prerequisites

A Tencent Cloud account has been registered with identity verification completed.
To register a Tencent Cloud account: click Sign up for a Tencent Cloud account.

Steps

Step 1: Go to the Purchase Page

Log in to the TDSQL Boundless console. On the Instance List page, click Create Instance to go to the purchase page.

Step 2: Select Basic Configurations

Basic Configuration
Configuration Item
Description
Instance Form
Select Serverless, which is billed based on the actual computing power (CCU) and storage space used, without the need to reserve resources with fixed specifications. It is suitable for scenarios with significant business load fluctuations, intermittent usage, or unpredictable capacity requirements.
Billing Mode
Serverless instances only support the Pay as You Go billing mode, which charges based on the actual computing power (CCU) and storage space used.
Region
Select the region where your business needs to be deployed. It is recommended to select the same region as your CVM. Cloud products in different regions cannot communicate via the private network, and the region cannot be changed after purchase.
Database Mode
Compatible with MySQL 8.0: It is compatible with the MySQL 8.0 protocol.
Compatible with HBase: It is compatible with HBase data types and APIs.
Kernel Version
Select the required kernel version.
Deployment Mode
Currently, only Single-AZ deployment is supported, meaning all resources are located in the same AZ, resulting in the lowest network latency. Single-AZ deployment carries disaster recovery risks. It is recommended to choose multi-AZ deployment for production environments.
AZ
Select the AZ for instance deployment.
Cloud products in different AZs under the same VPC can communicate via the private network. For example, a CVM in Guangzhou Zone 2 can access TDSQL Boundless in Guangzhou Zone 3 via the private network within the same VPC.
Peer Node Specification Configuration
Configuration Item
Description
Compute Configuration
CCU (Cloud Computing Unit) is the computing power metering unit for TDSQL Boundless. The specification of one CCU is one CPU core and 2 GB of memory.
Set the minimum and maximum computing power (CCU) for a single node. The Serverless instance automatically scales between the minimum computing power and maximum computing power based on the business load.
The default value range is 1 CCU - 16 CCU.
Number of Nodes
Defaults to 2, meeting the requirements for high-availability deployment.
Storage Billing Mode
The storage space of Serverless instances uses the Pay as You Go billing mode, which is settled based on the actual storage capacity occupied, and does not require pre-specifying a storage specification.

Step 3: Configure Network and Database

Network and Other Settings
Configuration Item
Description
Network
Supports VPC environments, allowing you to select the network and subnet for the instance. If the existing network is unsuitable, you can create a VPC or create a subnet.
Note:
A subnet is a network space that is logical within a VPC. You can create subnets in different AZs under the same VPC. Subnets in different AZs under the same VPC can interconnect via the private network by default.
After you select a network, the subnet is displayed by default as the subnet IP address in the same AZ as the selected instance. You can also manually select a subnet IP address from other AZs within the same region. Actual business connections follow the nearest principle, which does not increase network latency.
It is recommended that you select a VPC in the same region as your CVM. Otherwise, you cannot connect to the CVM and the database via the private network. The default setting is Default-VPC (default).
Custom Port
The database access port, which defaults to 3306, has a valid range: 1024 - 65535.
Tag
Add Tags to instances for categorized management of instance resources.
Database Settings
Configuration Item
Description
Instance Name
Name It Later: Set the instance name after the instance is created.
Name It Now: Set the instance name directly during creation.
Parameter templates
Select the required parameter template from the drop-down list. This applies only to instances with kernel version ≥ 21.6.x.
Read/Write Balanced (Default): Suitable for general business scenarios.
Write Optimized: Suitable for write-intensive workloads.
Read Optimized: Suitable for read-intensive workloads.
Character Set
Applies only to MySQL compatibility mode. The default value is UTF8MB4. Common optional values include UTF8, LATIN1, GBK, UTF8MB4, GB18030, and others.
Table Name Case Sensitivity
Applies only to MySQL compatibility mode. Specifies whether table names are case-sensitive. In MySQL compatibility mode, the case sensitivity setting for table names cannot be changed after configuration. Please configure with caution.

Step 4: Confirm Configuration Information

1. In the Confirm Configuration Information step, verify all configuration items.
2. Carefully read the Terms of Service at the bottom of the page and select I have read and agree to the Terms of Service.
3. Click Buy Now at the bottom right corner of the page.
After a successful purchase, you will be returned to the Instance List page. You will see the instance status displayed as "Delivering" (this typically takes 3 to 5 minutes, please wait patiently). Once the instance status changes to "Running", you can perform normal operations.
