Question

what is the best method to resize a pool to increase number of nodes in azure batch account that's running in production ?

Answer 1

The Azure portal for sure, it will ask you what to do about running and queued tasks. You can also issue Azure CLI commands, see az batch pool resize.

The absolute best way IMHO is to have an auto-scale formula, e.g.:

$NodeDeallocationOption = taskcompletion;

minNodes = 1;
maxNodes = 10;

activeTasks = $ActiveTasks.GetSample(1);
runningTasks = $RunningTasks.GetSample(1);

totalTasks = activeTasks + runningTasks;


nodes = min(max(minNodes, totalTasks), maxNodes);
$TargetDedicated = nodes;

Update min and max nodes, evaluate the formula (optional) and save it and the pool will rescale.
