Last updated: 2024-01-04 09:44:16

Tencent Cloud allows you to purchase a CLB instance on the official purchase page or via API. The two methods are detailed below:
Purchasing a CLB Instance on the Official Purchase Page
You can purchase a CLB instance on Tencent Cloud official website. There are two types of Tencent Cloud accounts, namely the bill-by-IP account and bill-by-CVM account. The accounts created after 00:00:00 on June 17, 2020 are of the bill-by-IP type. If you have created your account before that time, you can check your account type in the console as instructed in Checking Account Type.
1. Log in to the Tencent Cloud console and go to the CLB purchase page.
2. Select the following CLB configuration items as needed:
Bill-by-IP account
Parameter
Description
Billing mode
Supports pay-as-you-go billing.
Region
Select a region. For more information on the regions supported by CLB, see Region List.
Instance type
Supports the CLB instance type only. Starting from October 20, 2021, classic CLB instances can no longer be purchased. For more information, see Classic CLB End-of-Sale Notice.
Network type
Supports two network types: public network and private network. For more information, see Network Types.
Public network: CLB is used to distribute requests from a public network.
Private network: CLB is used to distribute requests from the Tencent Cloud private network. A private network instance does not support the following configuration items, and therefore they are not displayed by default: EIP, IP version, ISP, instance specification, network billing mode, and bandwidth cap.
The supported network types vary by billing mode:
In pay-as-you-go billing mode, both the public and private network types are supported.
EIP
If EIP is not selected, Tencent Cloud will assign you a public network CLB instance whose public IP address cannot be changed.
If EIP is selected, Tencent Cloud will assign you an EIP and a private network CLB instance, which has the similar features of public network CLB. (Only pay-as-you-go public network CLB instances allow you to select an EIP.)
 This feature is currently in beta. To try it out, submit a ticket. For the use limits, see Use Limits.
IP version
Supports the following CLB IP versions: IPv4, IPv6, and IPv6 NAT64. Only pay-as-you-go instances support the IPv6 version. For more information about other restrictions, see IP Versions. IPv6 CLB is currently in beta. To try it out, submit a ticket.
Network
CLB supports classic network and VPC.
The classic network is a public network resource pool for all Tencent Cloud users. The private IPs of all CVMs are assigned by Tencent Cloud. You cannot customize IP ranges or IP addresses.
A VPC is a logically isolated network space in Tencent Cloud. In a VPC, you can customize IP ranges, IP addresses, and routing policies.
A VPC is more suitable for use cases requiring custom configurations. Besides, the overall classic network products were officially discontinued on December 31, 2022. For details, see Ending Support for Classic Network. We recommend you choose a VPC.
ISP
Supports the following ISP types: BGP (multi-line), China Mobile, China Telecom, and China Unicom.
In pay-as-you-go billing mode, all of the above four options are supported. Currently, the static single-line IP is supported only in Guangzhou, Shanghai, Nanjing, Jinan, Hangzhou, Fuzhou, Beijing, Shijiazhuang, Wuhan, Changsha, Chengdu, and Chongqing. For the support information in other regions, see the console. If you want to try it out, contact the sales rep for application. Once your application is approved, you can select an ISP (China Mobile, China Unicom, or China Telecom) on the purchase page.
Primary/Secondary availability zone
The primary availability zone (AZ) is an AZ that currently sustains the traffic. The secondary AZ does not sustain traffic by default and will be used only when the primary AZ is unavailable. Currently, only IPv4 CLB instances in the Guangzhou, Shanghai, Nanjing, Beijing, Chengdu, Shenzhen Finance, Hong Kong (China), Seoul, Frankfurt, Singapore regions support primary/secondary AZs.
Instance specification
Supports shared and LCU-supported instances.
Shared instances guarantee performance according to their specifications. A single instance can sustain up to 50,000 concurrent connections, 5,000 new connections per second, and 5,000 queries per second.
An LCU-supported instances provide guaranteed performance according to specifications. A single instance can sustain up to Ten million concurrent connections, 1 million new connections per second, and 300,000 queries per second.
Network billing mode
Supports the following network billing modes: bill-by-bandwidth (monthly subscription and hourly bandwidth), bill-by-traffic, and bandwidth package.
A pay-as-you-go instance supports three network billing modes: bill-by-bandwidth (hourly bandwidth), bill-by-traffic, and bandwidth package. 
Bandwidth cap
The public network bandwidth cap of a shared CLB is 2 Gbps. For the private network bandwidth cap, it's suggested to set ‍a value within 5 Gbps. 
The bandwidth cap of an LCU-supported CLB instance depends on the selected specification. For details, see Instance Specifications Comparison.
Project
Select a project.
Tag
Select a tag key and value. You can also create a tag as instructed in Creating Tags and Binding Resources.
Instance name
The name can contain up to 60 characters, including letters, numbers, hyphens, underscores, and dots. If it is not specified, a name will be automatically generated by default.
