What is the function of Alibaba Cloud Invitation Codes?

Alibaba Cloud Invitation Codes primarily serve to provide discounts and promotions for new users. By using an invitation code, new customers can receive incentives such as service credits or price reductions on their initial purchases. This encourages users to try Alibaba's cloud services, effectively aiding both customer acquisition and retention.

In contrast, access to restricted services may require different types of permissions or subscriptions that are not related to the use of invitation codes. While codes can be involved in user authentication to some extent, that is not their primary function. Scheduling service maintenance typically involves different processes and tools, rather than being managed through invitation codes. Thus, the primary role of invitation codes is to attract new users with financial benefits.
