RBAC vs. LBAC: Which Scales for Multi-Tenant Dashboards?
- Multi-tenancy in observability platforms like Grafana often challenges traditional RBAC, leading to the adoption of LBAC.
- RBAC assigns permissions based on roles, while LBAC filters data dynamically based on labels, enabling fine-grained data isolation.
- RBAC simplicity suits single-tenant setups, but struggles at scale due to limited granularity and role explosion.
- LBAC offers scalable data isolation with dynamic policies, overcoming RBAC limitations in multi-tenant environments.
- RBAC alone presents challenges like role explosion, security risks, and operational overhead in multi-tenant Grafana setups.
- LBAC resolves challenges by simplifying management, enhancing security, and providing greater flexibility for multi-tenancy.
- Combining RBAC roles with label-based policies is recommended for effective multi-tenant dashboards in Grafana.
- Implementing LBAC with tools like Giam offers centralized management, granular data isolation, audit trails, and zero operational overhead.
- The future trend leans towards hybrid RBAC+LBAC models, backed by external enforcement tools, for secure multi-tenancy.
- RBAC and LBAC complement each other, with RBAC providing the base and LBAC offering granular control for secure multi-tenancy.
- Tools like Giam integrate RBAC and LBAC efficiently, simplifying secure multi-tenancy and empowering teams to focus on value delivery.
