Immediately, nothing. Within reason, AX will allow occasional spikes in usage beyond our guidelines, and we will not apply unnecessary limits.
Repeated spikes or high continued usage will prompt a dialogue: we'll reach out to learn more about your application and offer you a step up. Barring abuse or attack, we will not impose limits for any application without contacting the customer.
Customers whose usage claims a disproportionate percentage of resources for their current plan level may be asked to upgrade to the plan level that matches their needs.
