AWS EC2 Scaling Part-2 Video

W3schools.com collaborates with Amazon Web Services to deliver digital training content to our students.

EC2 Auto Scaling can be added as a buffer on top of your instances.

It can add new instances to the application when necessary and terminate them when no longer needed.

You can set up a group of instances.

Here you can set a minimum capacity of instances that will always be running. The rest will operate when necessary.

You can set the desired number of AWS EC2 instances in the scaling group.

However, the desired capacity defaults to your minimum capacity if not specified.

The last configuration is Maximum capacity.

Here you set the maximum capacity of instances to be used.

The Auto Scaling groups allow you to have a dynamic environment.

You set the minimum capacity, the desired number, and the maximum capacity.

The group will operate within the config and give you a predictable and cost-effective architecture.
