Using Cloud IAM (Identity and Access Management) is essential for controlling access to users and resources within Google Cloud. This service allows organizations to set specific permissions, roles, and policies associated with who can access their resources, ensuring that only authorized users can perform certain actions.

With Cloud IAM, administrators can define and manage roles that align with the principle of least privilege, which minimizes access rights for users to only what is necessary for their job roles. Additionally, IAM provides the ability to audit access activities, facilitating compliance and security monitoring.

The other services listed serve different purposes that do not directly relate to access control for users and resources. Hardware-based encryption focuses on securing data at rest or in transit rather than managing user permissions. Cloud VPN is utilized for securely connecting hybrid environments over the internet but does not control user access within Google Cloud resources. Cloud Interconnect deals with connecting on-premises networks to Google Cloud offerings at high bandwidth, which is also unrelated to user access management. Thus, utilizing Cloud IAM is the most relevant choice for effectively managing access control in Google Cloud.
