Due to the end-of-sale (EoS) for pay-by-specification Classic Load Balancer (CLB) instances, Alibaba Cloud Container Compute Service (ACS) now uses Network Load Balancer (NLB) instances by default when you create SLB-type Services through the console. Creating CLB instances through the console will only be available to whitelisted users and when created, will default to the pay-by-LCU billing method.
Impact scope
This change affects ACS clusters meeting the add-on version criteria specified below. Otherwise, you are not affected by this change.
Existing CLB or NLB Services are not affected and continue to operate normally.
