Tencent Cloud allows you to create 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.

Bill-by-CVM accounts

Private network CLB instances are free of charge, while public network CLB instances charge instance fees on an hourly pay-as-you-go basis. You can purchase public network on CVM. For more information on the network billing modes, please see Public Network Billing.
To purchase a CLB instance on the official website, perform the following:

1. Log in to the Tencent Cloud console and go to the CLB purchase page.
2. For the Instance type, Cloud Load Balancer is recommended.
3. Select attributes as needed, including the network type and project. For attribute details, please see Product Attribute Selection.
   
4. Confirm and pay for the selected CLB instance.
5. CLB service will be activated once the payment completes. You can now configure and use the CLB instance.

Bill-by-IP accounts

Private network CLB instances are free of charge. Public network CLB instances charge instance fees and public network fees on a monthly subscription or pay-as-you-go basis. The monthly-subscribed public network can only be billed by bandwidth, while the pay-as-you-go public network can be billed by bandwidth, traffic, and shared bandwidth package.
