Which AWS service or tool can the company use to launch the number of EC2 instances that will be needed to handle the workload?

Explanations:

Elastic Load Balancing (ELB) distributes incoming application traffic across multiple targets, such as EC2 instances. While it helps manage traffic to EC2 instances, it does not automatically launch new instances in response to workload changes.

Amazon EC2 Auto Scaling is designed specifically to automatically launch or terminate EC2 instances based on the defined policies, ensuring that the application has the appropriate number of instances running to handle workload fluctuations.

AWS App2Container (A2C) is a tool that simplifies the process of containerizing applications and deploying them to Amazon ECS or EKS. It does not manage EC2 instance scaling or launching.

AWS Systems Manager is a management service that helps automate tasks across AWS resources but does not directly handle scaling EC2 instances. It provides operational data, but not automatic instance launching based on workload.
