Alibaba Cloud ACP-Cloud1 - ACP Cloud Computing Certification

Alibaba Cloud SLB can distribute user requests to backend ECS instances, but these ECS instances do not have to have the same specification (CPU, Memory). SLB virtualizes the added group of ECS instances in the same region into an application pool, and you can manage backend servers through either the default server group, a primary server group, or VServer groups. You can add ECS instances of different specifications to the same server group or VServer group according to your needs. SLB supports weighted round-robin (WRR) and weighted least connections (WLC) algorithms to balance the load among backend servers with different weights. References:

In Alibaba Cloud Object Storage Service (OSS), once a bucket is created, its name cannot be changed. This rule aligns with OSS's design to ensure global uniqueness and consistency in bucket naming across regions. Users can create multiple buckets, and each bucket can store an unlimited number of objects, provided the bucket name remains unique and immutable after creation.
