Cloud IAM
Cloud IAM is a Google Cloud Platform service designed for fine-grained access control and visibility. It allows administrators to centrally manage permissions for cloud resources, ensuring that only authorized users and services can interact with specific assets. This tool is essential for maintaining security and compliance by defining exactly who can do what within your infrastructure.
You should choose this solution when you need centralized management of access policies across your Google Cloud environment. Be aware that there is no free tier available for this service. Instead, it operates on a pay-as-you-go pricing model, meaning you will incur costs based on actual usage rather than a fixed monthly fee or a complimentary allowance.
