It is generally good practice to move your systems as close to users as possible. (As mentioned previously, this does not always directly correlate to physical location but to closest in network hops.)

The monitoring systems defined previously, combined with the discussed performance and cost-optimization metrics, will allow you to determine when it is appropriate to consider moving to multiple cloud providers.
