Explain the difference between vertical scaling and horizontal scaling in AWS.
Vertical Scaling: Increasing instance size (e.g., t2.micro → m5.4xlarge).
Horizontal Scaling: Adding more instances behind a load balancer (scaling out).
Example:
Vertical = upgrading to a bigger RDS DB.
Horizontal = adding more EC2s in an Auto Scaling Group.
Horizontal Scaling: Adding more instances behind a load balancer (scaling out).
Example:
Vertical = upgrading to a bigger RDS DB.
Horizontal = adding more EC2s in an Auto Scaling Group.
