Grafana's access management system can be streamlined by using teams to manage user permissions and access effectively, with the blog post explaining how to implement such a system by integrating with identity providers like Entra ID, Okta, and Keycloak. By adopting a team-based structure over organizations or custom roles, Grafana encourages collaboration and transparency while maintaining controlled isolation and data security. Users are guided through the setup process, involving synchronization of external user directories, mapping teams to resources, and configuring permissions for data sources and dashboards. The post highlights the benefits of using Terraform for consistent and scalable configuration management, ensuring version-controlled and reproducible setups. Future improvements in Grafana are anticipated to enhance resource management, team permissions, and identity provider integration. Grafana Cloud offers these features across all its plans, including a free tier, making it accessible for various use cases.
