Which user repository can be utilized in a managed cluster?

In a managed cluster setup within Dynatrace, the internal user database is specifically designed to maintain and manage user information efficiently. This repository is integrated into the architecture of Dynatrace and enables seamless synchronization and management of user identities and roles across the cluster nodes.

Utilizing the internal user database offers various advantages, such as simplified user management and reduced latency since the data is readily accessible within the system. It ensures consistent user experience and security policies across different instances of the Dynatrace managed cluster.

The other options, while potentially useful for different scenarios, do not match the requirements for a managed cluster. The external user database might introduce complexity in terms of integration and synchronization. Cloud-based storage is typically not optimized for real-time user authentication and could face latency issues. Similarly, a network file system is not suited for dynamic user management in a cluster environment, as it can lead to inconsistencies and performance bottlenecks. Thus, the internal user database is the most appropriate and efficient choice for maintaining user data in a managed cluster setup.
