These are baselines and the optimal varies based on specific environment needs.  This section gives summary of the nodes considerations that we have discussed in the  previous section. GLYPH<SM590000> Boot node considerations: – Externalizing your boot node alleviates some resource constraints during cluster  installation. GLYPH<SM590000> Master node considerations: – At least 3 nodes ensures a quorum can be reached upon failure. – Additional nodes help ensure the ability to recovery from failure. – Consider minimum recommendations to be applicable to only non-production  environments. – Can Load Balance masters, but only one is the primary master. – Only one master node is active at any point in time: 38  IBM Cloud Private System Administrator’s Guide
