- Amazon EC2 Auto Scaling is a service that automatically scales your EC2 instances based on demand. It can be used to scale your ecommerce application up or down based on the number of customers visiting your website. It also supports automatic OS updates.
Therefore, Amazon EC2 Auto Scaling is the best choice for this scenario. It offers automatic scaling and OS updates, which will help the company meet its requirements.
