App Runner is a service in AWS that allows you to quickly deploy web applications and API’s. No deep knowledge on infrastructure or docker is needed, you simply provide a docker image / source code and define the amount of resources you’d like to use, whether you want autoscaling, and health checks. The site is then automatically connected to a load balancer, encryption is provided, and you can connect it to your VPC to connect it to any databases, queues, etc. App Runner is a good way to simplify deployment or even perform rapid deployment. You can also get images from the public ECR as well and deploy them in App Runner.
