Question
Which of the following is a way to use Amazon EC2 Auto Scaling groups to scale capacity in the AWS Cloud?a.Scale the size of EC2 instances up or down automatically, based on demand.b.Scale the number of EC2 instances in or out automatically, based on demand.c.Transfer unused CPU resources between EC2 instances.d.Use serverless EC2 instances.
Solution
The correct answer is b. Scale the number of EC2 instances in or out automatically, based on demand.
Amazon EC2 Auto Scaling helps you ensure that you have the correct number of Amazon EC2 instances available to handle the load for your application. You create collections of EC2 instances, called Auto Scaling groups. You can specify the minimum number of instances in each Auto Scaling group, and Amazon EC2 Auto Scaling ensures that your group never goes below this size. You can specify the maximum number of instances in each Auto Scaling group, and Amazon EC2 Auto Scaling ensures that your group never goes above this size. If you specify the desired capacity, either when you create the group or at any time thereafter, Amazon EC2 Auto Scaling ensures that your group has this many instances.
If you specify scaling policies, then Amazon EC2 Auto Scaling can launch or terminate instances as demand on your application increases or decreases. For example, the following Auto Scaling group has a minimum size of 1 instance, a desired capacity of 2 instances, and a maximum size of 4 instances. The scaling policies increase the capacity of the group when the load on the instances is high, and decrease the capacity when the load is low.
