Tencent Cloud allows you to create a CLB instance on the official purchase page or via API. The two methods are detailed below:

Creating a CLB instance on the official purchase page

You can purchase a CLB instance on Tencent Cloud official website. Private network CLB is free of charge, while public network CLB only charges instance fees on an hourly pay-as-you-go basis.
