Techniques are provided for maintaining snapshots of state information for a plurality of resource entities, within a distributed cloud service. A first snapshot of state information for the plurality of resource entities is maintained at an endpoint in persistent storage. A request to modify resources allocated to resource entities is received. A virtual lock on the state information reflected in the first snapshot is obtained. Upon obtaining the virtual lock, a service determines, based on the first snapshot, that there are available resources to perform the request to modify resources. A second snapshot of the state information, reflecting the modification of resources allocated to resource entities, is then generated and stored at the endpoint in persistent storage. The virtual lock on the state information is released and the resources allocated to the resource entities are modified according to the request.
