Which of the following are characteristics of the Auto Scaling service on AWS?

The characteristics of the Auto Scaling service on AWS include enforcing a minimum number of running EC2 instances, launching instances from a specified Amazon Machine Image (AMI), and responding dynamically to changing conditions.

Enforcing a minimum number of running EC2 instances ensures that your application has the desired level of availability and performance even during peak loads. This feature allows organizations to maintain a baseline of resources that can handle expected workloads without interruption.

Launching instances from a specified AMI enables users to quickly and easily deploy scaling groups with consistent configurations, ensuring that all instances share the same software setup. This contributes to a reliable cloud application environment where instances can be automatically replaced or scaled without additional manual configuration.

The ability to respond to changing conditions is fundamental to the Auto Scaling service. It allows the scaling process to react to real-time metrics and application demands, such as CPU usage or request counts, ensuring that resources are utilized efficiently while minimizing costs during lower demand periods.

This dynamic adjustment capability is crucial for maintaining application performance and cost-effectiveness in a cloud environment.
