ReplicaSets

ReplicaSets ensure a specified number of identical pod replicas are running at any given time. They maintain high availability and scalability by automatically replacing failed pods and balancing workloads across nodes in a Kubernetes cluster.

When the user goes to the ReplicaSets tab the list of ReplicaSets will be shown.

From here users can select the ReplicaSets and review all the details, status, configuration of the replicasets.

Use Case of ReplicaSets -

• High Availability
• Scaling Applications
• Load Balancing
• Self-healing
