horizontal and vertical scaling cluster difference in hadoop

Expert Contributor

Hi,


Suppose i have a server having 128 GB RAM and 32 cores. I am creating 4 VMs on this server each having 32 GB RAM and 8 cores. Will each VM works as worker node ? does it gives parallel data processing performance ?

what will be the performance difference between 4 VMs as worker nodes on single server and 4 physical servers as worker nodes having same capacity(32 GB RAM and 8 cores) ?

Can anyone help me to clear this doubts ?


Thanks,

Heta
