Dear Alibaba Cloud Customer,
In May 2017, guaranteed-performance instances of Server Load Balancer were available for beta trial. The beta phase will end on March 31, 2018. Starting from April 1, 2018, Alibaba Cloud will charge capacity fees for guaranteed-performance instances of Server Load Balancer. Capacity fees will be included in bills for Server Load Balancer. To avoid service disruptions that may occur as a result of failed payments, please make sure that your payment method is valid and can cover the capacity fees incurred. Shared-performance instances of Server Load Balancer will remain available and will not incur capacity fees.
Guaranteed-performance instances will be charged on a Pay-As-You-Go basis. This billing method offers you better cost-effectiveness, where capacity fees are charged only for the actual used capacity, regardless of the specification purchased. In addition, the lowest specification (slb.s1.small)guaranteed-performance instances will continue to be free from capacity fees.
