A company wants to ensure their application has the right amount of Amazon EC2 compute capacity at all times to handle variable traffic loads. Which AWS service or feature should they use to automatically add or remove EC2 instances based on demand?
AWS Auto Scaling
Elastic Load Balancing
AWS CloudFormation
Amazon S3
The correct answer is AWS Auto Scaling. AWS Auto Scaling monitors your applications and automatically adjusts capacity to maintain steady, predictable performance at the lowest possible cost. It can automatically add EC2 instances during demand spikes to maintain performance and remove them when traffic is low to reduce costs. Elastic Load Balancing works with Auto Scaling to distribute traffic to the instances, but it does not add or remove the instances itself. AWS CloudFormation is an infrastructure as code (IaC) service used to provision and manage resources, but it does not dynamically scale them based on live traffic metrics. Amazon S3 is an object storage service and is not used for compute scaling.
