VMware vSphere environments are typically managed with the VMware vSphere® Client or the VMware vSphere Web Services SDK.
Large numbers of connected vSphere Clients and vSphere Web Services SDK Clients can affect the performance of a vCenter Server. Exceeding the supported maximums, even if it seems to work, is even more likely to affect vCenter Server performance.
Note:
For supported maximums, see VMware Configuration Maximums, then select VMware Cloud on AWS for Product, and appropriate choices for Version and Categories.
