In Dynatrace Managed installations, how many nodes can a cluster contain?

In Dynatrace Managed installations, a cluster can indeed contain two or more nodes, which is vital for achieving high availability and load balancing. When you have multiple nodes in a cluster, it allows the workload to be distributed effectively amongst them. This setup also provides redundancy; if one node fails, the others can continue to operate, ensuring that monitoring capabilities are maintained without interruption.

Having multiple nodes helps in scaling the performance of the Dynatrace Managed environment. As the demand on resources increases, additional nodes can be added to the cluster to meet this demand while maintaining system stability and responsiveness. A minimum of two nodes is necessary to form a cluster, but adding more nodes brings additional benefits in terms of resilience and processing capacity.

On the other hand, a single node installation doesn't leverage the benefits of clustering, such as redundancy and load distribution, which are essential for enterprise-grade monitoring solutions. Therefore, while having at least two nodes is the foundational requirement for a cluster, setting up a configuration that includes three or more nodes is common practice for larger, more complex environments.
