Google Cloud IAM
Google Cloud IAM (Identity and Access Management) is a service that provides centralized control over access to Google Cloud resources. It allows administrators to define who (users, groups, service accounts) has what access (roles and permissions) to which resources, enabling fine-grained security management across Google Cloud projects and services. IAM helps enforce the principle of least privilege by granting only necessary permissions to users and applications.
Developers should learn Google Cloud IAM when building or managing applications on Google Cloud Platform to secure resources, control access for teams, and comply with security policies. It is essential for use cases like multi-tenant applications, automated deployments with service accounts, and auditing access logs for compliance, as it integrates with other Google Cloud services like Compute Engine, Cloud Storage, and BigQuery.
