AutoScaling has two components: Launch Configurations and Auto Scaling Groups.

  • Launch Configurations hold the instructions for the creation of new instances. …
  • Scaling Groups, on the other hand, manage the scaling rules and logic, which are defined in policies.

Which of the following are elements of an Auto Scaling group?

An Auto Scaling group must have a minimum size and a launch configuration defined in order to be created. Health checks and a desired capacity are optional.

Which components should be configured for enabling Auto Scaling?

With metric-based autoscaling, you can use CPU or memory utilization to trigger autoscaling events. You then define scale-out and scale-in rules. These rules take a threshold percentage and a number of instances that you want to add (scale-out) or remove (scale-in) from the pool.

Which are the two types of compute autoscaling?

You can apply the following types of autoscaling to an instance pool:

  • Metric-based autoscaling: An autoscaling action is triggered when a performance metric meets or exceeds a threshold.
  • Schedule-based autoscaling: Autoscaling events take place at the specific times that you schedule.

What can users use to configure autoscaling?

You can configure autoscaling by using PowerShell, the Azure CLI, an Azure Resource Manager template, or the Azure portal. For more detailed control, use the Azure Resource Manager REST API.
