What is the maximum number of nodes supported in an ArcGIS Enterprise deployment?

The correct answer is that there is no hard limit on the number of nodes supported in an ArcGIS Enterprise deployment, but performance can degrade with an increasing number of nodes. This reflects the scalability of ArcGIS Enterprise, which is designed to handle various deployment scenarios from small to large organizations.

In practical terms, while the architecture can scale to a large number of nodes, as the number of nodes increases, so does the complexity of managing the deployment. Factors such as network latency, data synchronization, and load balancing between those nodes can impact overall performance. Therefore, while it's technically feasible to add many nodes to the system, there is a balance to be maintained for optimal performance.

The other answers suggest specific numerical limits, which do not account for the flexible scalability of the system or the consideration of performance metrics. This underscores the importance of understanding system capabilities and operational constraints in planning for an effective ArcGIS Enterprise deployment.
