Cluster Configuration Best Practices

[Sandy21]

I have a cluster with the configuration of 400 GB RAM, 160 Cores.

Which of the following would be the ideal configuration to use in case of one or more VM failures?

Cluster A: Total RAM 400 GB

      Total Cores 160

  Total VMs: 1

  400 GB/Exec & 160 cores/Exec

Cluster B: Total RAM 400 GB

      Total Cores 160

  Total VMs: 2

  200 GB/Exec & 80 cores/Exec

Cluster C: Total RAM 400 GB

      Total Cores 160

  Total VMs: 4

  100 GB/Exec & 40 cores/Exec

Cluster 😧 Total RAM 400 GB

      Total Cores 160

  Total VMs: 8

  50 GB/Exec & 20 cores/Exec

Cluster E: Total RAM 400 GB

      Total Cores 160

  Total VMs: 16

  25 GB/Exec & 10 cores/Exec

@Santhosh Raj​ can you please confirm cluster sizes you are taking are related to driver and worker node. how much you want to allocate to Driver and Worker?

once we are sure about type of driver and worker we would like to pick, we need to enable autoscaling to have workers to handle your load. best practices wise you need to

1. Initially check data size
2. how do you want to run (all purpose or job cluster)
3. Go from small cluster size and Increase based on performance that you are expecting
