Today, AWS App Runner launched improvements for managing Auto-Scaling Configuration (ASC). App Runner makes it easier for developers to quickly deploy containerized web applications and APIs to the cloud, at scale, and without managing infrastructure. With App Runner, you do not have to manage load balancer for your service(s). App Runner automatically scales compute resources, specifically instances, up or down for your App Runner service. Automatic scaling provides adequate request handling when traffic is heavy, and reduces your cost when traffic slows down. You can control auto scaling settings through a sharable resource called AutoScalingConfiguration.
