Node autoscaling is enabled and resizes the number of nodes based on cluster load..
What is step scaling in AWS?

What is the purpose of auto scaling?
What is Auto Scaling in Cloud Computing? Autoscaling is a cloud computing feature that enables organizations to scale cloud services such as server capacities or virtual machines up or down automatically, based on defined situations such as traffic ir utilization levels.
What is the difference between auto scaling and load balancing?
Load balancing evenly distributes load to application instances in all availability zones in a region while auto scaling makes sure instances scale up or down depending on the load.
What is auto scaling in Kubernetes?
Advertisements. Autoscaling is one of the key features in Kubernetes cluster. It is a feature in which the cluster is capable of increasing the number of nodes as the demand for service response increases and decrease the number of nodes as the requirement decreases.
What is ReplicaSet in Kubernetes?
A ReplicaSet is defined with fields, including a selector that specifies how to identify Pods it can acquire, a number of replicas indicating how many Pods it should be maintaining, and a pod template specifying the data of new Pods it should create to meet the number of replicas criteria.
How does Kubernetes know to scale?
Cluster autoscaler is used in Kubernetes to scale cluster i.e. nodes dynamically. It watches the pods continuously and if it finds that a pod cannot be scheduled, then based on the PodCondition , it chooses to scale up. This is far more effective than looking at the CPU percentage of nodes in aggregate.
What is an AWS Auto Scaling group?
An Amazon EC2 Auto Scaling group (ASG) contains a collection of EC2 instances that share similar characteristics and are treated as a logical grouping for the purposes of fleet management and dynamic scaling.
