Scale-up in AWS is increasing the hardware configuration of the specific instance
-----------------------------------------------------------------------------------------------------------

Let's take a look at Scale-up in AWS.
How do we increase the hardware configuration such as Harddrive/RAM/CPU?

Harddrive - We can increase from the Volumes - Actions - Modify volume - Specify new size - Confirmation to modify.
For this, we don't have to stop the instance.

RAM&CPU - We must stop the instance from making any changes as this is changing the instance type from one instance to another instance
Please note that the changes to RAM&CPU go together as we need to use the existing instances given by AWS.
Select the instance - Actions - Instance settings - Change instance type - Select the new instance correctly - Apply.

Scale-out - Without making any changes to existing EC2, and launching a new instance is nothing but Scale-out.

Scale in - Without making any changes to existing EC2, and removing an instance is nothing but Scale in

Example of Horizontal scaling: Autoscaling
