 ### Cause
 
-When you request to start or allocate the first VM in a proximity placement group, the data center is selected automatically. If the required VM size is unavailable in that data center, the request fails. In scenarios with elastic workloads where VM instances are added or removed dynamically, enforcing a proximity placement group constraint can lead to an allocation failure, indicating that the allocation request could not be completed.

 ### Why allocation failures happen
 
-When an allocation has a large number of restrictions, there's a higher chance of failing to find free resources since the available resource pool is smaller. Furthermore, if your allocation request is restricted, such as when using proximity placement groups but the type of resource you requested isn’t supported by the set of clusters and nearby ones, your request fails even if the cluster has free resources. The following Diagram 2 illustrates the case where an allocation fails because the candidate clusters associated with the proximity placement group don't have free resources. Diagram 3 illustrates the case where an allocation fails because the candidate clusters associated with the  proximity placement group don’t support the requested VM size, even though the clusters have free resources.
