CLB Instance Upgrade and Price Adjustment

Last updated: 2021-11-09 11:40:00

    Tencent Cloud plans to upgrade the architecture of all CLB instances staring from 00:00:00, November 2, 2021 (UTC +8). After the upgrade, the guaranteed performance of each shared CLB instance will be increased to 50,000 concurrent connections, 5,000 new connections per second and 5,000 QPS

    The performance is guaranteed for each CLB instance.


    • Before the upgrade, shared CLB instances share resources of one cluster, which may affect the performance in case of resource contention.
    • After the upgrade, the basic performance for every individual shared CLB instance is guaranteed. When the required performance exceeds the guaranteed value, resource contention may occur.

    Price Adjustment

    The price adjustment covers all CLB instances (former "Application Load Balancer instances") and Classic CLB instances.

    • A private network CLB instance is priced as 0.686 USD per day (1.029 USD per day for some regions).
    • A public network CLB instance is priced as 0.686 USD per day (1.029 USD per day for some regions).

    See below for the new instance prices:

    How do I optimize my bill?
