1. Overview
To ensure sufficient capacity and performance, the recommended minimum configuration for the cluster is to have:
-
3 worker nodes with a combined total of:
-
at least 24 CPUs and 48GB of RAM.
-
Each worker node needs to provide:
-
a minimum of 100GB local storage (temporary data)
-
an external volume capacity (EBS or similar) of 500GB that is necessary for data persistence.
-
Please note that the resources allocated to the master nodes should be separate from the ones mentioned above.
