How can users manage access control on Alibaba Cloud?

Managing access control on Alibaba Cloud is predominantly achieved through Resource Access Management (RAM). RAM is a key feature that enables users to create and manage access rights for their cloud resources efficiently. With RAM, administrators can define roles, user accounts, and policies that specify what actions users can perform on which resources. This granular approach to access control enhances security by ensuring that only authorized individuals have access to sensitive data and resource configurations.

In contrast, using Virtual Private Networks (VPN) focuses primarily on securing network connections rather than controlling who can access specific resources. Simple password protection lacks the sophistication needed for comprehensive access management, as it does not allow for varied permissions or roles and can pose security risks if passwords are weak or compromised. Data backup solutions are essential for data recovery and integrity, but they do not play a role in managing user permissions or access to resources. Thus, RAM is the most suitable and effective tool for access control on Alibaba Cloud.
