Are the Flows executed on the same server as my Dynamics CE online server?
Can a use of huge amount of flows (for e.g. creating, updating, deleting records in Dynamics CE) affect the performance for the end users in Dynamics CE?
Flows are stored and executed in your tenant, but in any case, It shouldn't affect the performance of any other products (Dynamics, SharePoint, Planner, etc.). Request limits and allocation depends on the user plan: https://docs.microsoft.com/es-es/power-platform/admin/api-request-limits-allocations
Apart from that, there are some limits and configurations on Flow to avoid some problems (time outs, recursive calls, etc.): https://docs.microsoft.com/en-us/flow/limits-and-config#looping-and-debatching-limits
Hope it helps!
