 ## How is resizing different from autoscaling ?
 Autoscaling is the idea of launching new clusters for jobs in the queue. 
 Resizing a cluster is changing the size of a cluster. In some case growing your cluster may be a better idea, be aware that this may lead to capacity errors. Because Oracle CLoud RDMA is non virtualized, you get much better performance but it also means that we had to build HPC islands and split our capacity across different network blocks.
